Hi Erik,

There has been a recent thread of activity on the Aeropac list
regarding interop between The GPS Flight telemetry system and 
the ARTS2 GPS system. So far, we've concluded these systems may
not interoperate. 

Basically, there are 6 Telemetry system channels available in 
The ARTS DataAnalyzer (0-6) aka "Telemetry Channel". Using RadioRX,
The same 0-6 channels are configurable for the receiver.

I've used all of this functionality before with 3 GPS transmitters
And everything works great - thanks!

The Question is as follows: the 9XStream 900Mhz modem operates from 
902 - 928Mhz; what is the mapping algorithm between channel selection
Of 0-6 and this frequency range. Assuming (928-902)/7 = 3.714Mhz per channel
We can do some simple math but I am not sure if this is correct. 

So, if I use channel 0, is this 902Mhz - 905.714Mhz?
If I use Channel 1, is this 905.715- 909.429? 

Basically, I just need the correlation between channels 0-6 and 
The actual frequency ranges used. 


Thanks,
-James

Hi James,

My understanding is that both the ARTS and the GPS flight systems use OEM Maxstream (Now digi) Radio modem sets.

GPS flight uses a binary propritary data stream, and the ARTS can use a binary propritary data stream or stock NEMA.

Researching documentation on Interferance possibilities at the DIGI website might help. I think what your looking for is not interoperability but you are trying to avoid interferance. These are frequency hopping devices and it set up with the correct/different spreading codes on each should be able to operate with many units all runing at the same time.

James,

The MaxStream 9XStream radio modules actually use frequency hopping spread
spectrum, so your math does not apply here. The "channels" are actually
seven different hopping patterns over the same 25 frequencies. (ie, all
"channels" will use all 25 frequencies, but at different times so they will
not interfere with each other)

Thanks,
Erik

Thanks Art,

I read through the brief marketing sheet on the site.
We just need to know if it is possible to black-out a range in 900Mhz band
so as to allow for the GPS/Flight and ARTS2 to operate at the same time.

Hi Erik,

I guess we don't know how they allocate channels within a channel ID
Only that we have 7 channels and they are spread-spectrum so this means
We can't rely on anything other then 902-928Mhz is unusable while these
Devices are operating.

Our goal is to allow a GPS/Flight and ARTS2 telemetry transmitter to
Operate concurrently.

James,
There is no interference between the units if they are set to different
channels. Have tested with 3 GPS/Flight modules (1 in NMEA mode). Mike Brest
and I have moved our GPS/Flights to channel 4, Ron Rickwald has moved his
ARTS to channel 5 and we added a channel/slot column to our sign-up sheet
http://spreadsheets.google.com/ccc?key=rJ4e5z1noBubQ3xuCiifs3A
<http://spreadsheets.google.com/ccc?key=rJ4e5z1noBubQ3xuCiifs3A&inv=aeropac-
members at mylist.net> &inv=aeropac-members at mylist.net

Our suggestion is that the GPS/Flight units move to even channels and we
keep the ARTS units on the odd channels and the default 0. 

Thanks to all for the help. Seems us novices have been introduced to a
powerful product feature that we were unaware of.

Subject: ARTS GPS Receiver and Telemetry system

Hi Erik,

There has been a recent thread of activity on the Aeropac list
regarding interop between The GPS Flight telemetry system and 
the ARTS2 GPS system. So far, we've concluded these systems may
not interoperate. 

Basically, there are 6 Telemetry system channels available in 
The ARTS DataAnalyzer (0-6) aka "Telemetry Channel". Using RadioRX,
The same 0-6 channels are configurable for the receiver.

I've used all of this functionality before with 3 GPS transmitters
And everything works great - thanks!

The Question is as follows: the 9XStream 900Mhz modem operates from 
902 - 928Mhz; what is the mapping algorithm between channel selection
Of 0-6 and this frequency range. Assuming (928-902)/7 = 3.714Mhz per channel
We can do some simple math but I am not sure if this is correct. 

So, if I use channel 0, is this 902Mhz - 905.714Mhz?
If I use Channel 1, is this 905.715- 909.429? 

Basically, I just need the correlation between channels 0-6 and 
The actual frequency ranges used. 


Thanks,
-James

GPSFlight units used to use MaxStram radio modules, the same modules used in
the ART telem system. Do they still use those modules? If so, then you can
set them for a different channel and they will interoperate without
interference.

Thanks,
Erik

Hi Erik,

I guess we don't know how they allocate channels within a channel ID
Only that we have 7 channels and they are spread-spectrum so this means
We can't rely on anything other then 902-928Mhz is unusable while these
Devices are operating.

Our goal is to allow a GPS/Flight and ARTS2 telemetry transmitter to
Operate concurrently.

The MaxStream 9XStream radio modules actually use frequency hopping spread

More results after the launch.

Yup, It should be all working with even (GPS/Flight) and Odd (ARTS2) since
they use the
Same MaxStream base-stations. More on even/odd allocation after mudroc.

They probably meant that the software was not interoperable, as GPSFlight
uses a proprietary binary protocol. The ARTS telem system, in ARTS mode,
also uses a proprietary (but open!) protocol, and standard GPS NMEA data
when in GPS mode.

Erik

They do use the same module, Erik, although the folks at GPSFlight  
told me they were not interoperable.  They told me they were going to  
send me a unit to test, but never followed up.

By the way, do you know anyone who will build custom GPS antennae for  
the TX-900?  I'd like to get some with shorter leads.  I tried  
splicing two and did a terrible job...

GPSFlight units used to use MaxStram radio modules, the same modules used in
the ART telem system. Do they still use those modules? If so, then you can
set them for a different channel and they will interoperate without
interference.

Thanks,
Erik

Hi Erik,

I guess we don't know how they allocate channels within a channel ID
Only that we have 7 channels and they are spread-spectrum so this means
We can't rely on anything other then 902-928Mhz is unusable while these
Devices are operating.

Our goal is to allow a GPS/Flight and ARTS2 telemetry transmitter to
Operate concurrently.

Thanks,

James,

The MaxStream 9XStream radio modules actually use frequency hopping spread
spectrum, so your math does not apply here. The "channels" are actually
seven different hopping patterns over the same 25 frequencies. (ie, all
"channels" will use all 25 frequencies, but at different times so they will
not interfere with each other)

Thanks,
Erik

Hi Erik,

There has been a recent thread of activity on the Aeropac list
regarding interop between The GPS Flight telemetry system and 
the ARTS2 GPS system. So far, we've concluded these systems may
not interoperate. 

Basically, there are 6 Telemetry system channels available in 
The ARTS DataAnalyzer (0-6) aka "Telemetry Channel". Using RadioRX,
The same 0-6 channels are configurable for the receiver.

I've used all of this functionality before with 3 GPS transmitters
And everything works great - thanks!

The Question is as follows: the 9XStream 900Mhz modem operates from 
902 - 928Mhz; what is the mapping algorithm between channel selection
Of 0-6 and this frequency range. Assuming (928-902)/7 = 3.714Mhz per channel
We can do some simple math but I am not sure if this is correct. 

So, if I use channel 0, is this 902Mhz - 905.714Mhz?
If I use Channel 1, is this 905.715- 909.429? 

Basically, I just need the correlation between channels 0-6 and 
The actual frequency ranges used. 


Thanks,
-James

They probably meant that the software was not interoperable, as GPSFlight
uses a proprietary binary protocol. The ARTS telem system, in ARTS mode,
also uses a proprietary (but open!) protocol, and standard GPS NMEA data
when in GPS mode.

They do use the same module, Erik, although the folks at GPSFlight

By the way, do you know anyone who will build custom GPS antennae for

Tom,

We have it all sorted out. We just need to changed your channel number to 1.
The issue is that the default ARTS2 GPS comes up in Channel 0 which is the
same
As the default for GPS/Flight. What this means is that we need to configure
the
Device before we go to the playa, that's all. We can meet up at Brunos and
do
A bench test if you'd like.

	Request
Message-ID: <0KLG00LQWL56GP40@vms173019.mailsrvcs.net>

 
Hello ARTS List
 
I have an ARTS2 that was involved in a high impact crash last season.  Under
diagnostics, sensors, the Barometric is reading 932 and accelerometer is at
514.  Unfortunately, I never recorded the baseline readings prior to
crashing.  Can anyone tell me if these are good or bad compared to your unit
baseline sensor readings?  As I understand it from an electronics
engineering racketeer friend, an accelerometer of this design type can be
damaged with enough impact force.
 
Estimated 9,300 Lbs-f at impact.  A commercially sewn loop opened up on main
and free fall ensued - ugly.  Thank the rocket gods for G-10 though.

Hi Jody,
when in DIAG mode if you shake the unit left and right does the acel number 514 (about middle range) move left and right?

The Baro number will depend on your baro pressure when you read the readings. Can you apply presure and/or suction to the baro sensor gently and see the reading change?

Also, test fire some ematches after a crash in the test fire modes.

I've had an ARTS 1 fall from 7000 feet to the playa and it still works fine. But I had one other one in a playa crash that pulled a PCB trace off the e-match firing port and won't fire main anymore.

Thanks Art, Dennis and Jeff.  I also measured another brand new unit before
catching up to your e-mails and it is in that same range.  The sensors
respond to shaking also on the crashed unit.  I think it will be good to go
and I always fly with a low cost, non-logging, back-up too.

I am not having trouble understanding the telemetry system with an ARTS2
piggy back per se.  BUT, I have managed to confuse myself on the bigger
picture of using an  e-Trex Garmin to load the landing coordinates and go
find the vehicle.  I have not flown it yet, but the rocket it is intended
for is a 4" Talon type design with a 54mm mount.  That baby on a L1400 will
be out-a-site - hence the investment in tracking.
 
So my question is while using RadioRx in ARTS mode, what exactly do I do in
order actually find the rocket after she sets down if I loose visual?  What
is the rest of the process.
 
Can RadioRx write tracks/waypoints to a Garmin eTrex ?  How about transfer
to Google Earth, VisualGPS or ExpertGPS.  BTW users of ExpertGPS, how do you
get maps when you don't have internet on the laptop in the middle of a farm

tracking.
 
Help me see the BIG picture on how to use this cool system.   Maiden flight

Subject: [ARTS] Performance of ARTS Telemetry System
Message-ID: <1ED833C1BDA44115BCF6637012AEF451@BrianPC>

I am looking for people with practical experience with the telemetry system.

I have the ARTs Telemetry system and have sent it up in a rocket 3 times. I am preparing for my Level 3 and plan on sending it up must higher and faster. I am looking for some one that can tell me if using it as is will work best or should I look at improving the receiver antenna or use the current antenna but elevating it, and or if elevating it will improve my tracking with the GPS telemetry system.

So to date: I have only flown it to 4200 ft, Max acceleration of 350 ft / sec and Max velocity of 637 ft/sec. Of the 3 flights, the farthest it has gone down range is 1/2 mile

On my 3 flights - it has performed differently

All three flights at the same field, basically flat and no tree's or buildings to interfere with the signal. No hills either.

1) Lost connection at 2500 ft
2) Didn't lose connection at all - tracked all the way to the ground
3) Lost connection at 98 ft

The second flight I had the receiver elevated to about 6 ft, the 1 and 3rd I had at about 3 feet on a table.

1) Will I improve my reception if I elevate the receiver - say to 10 or 15 ft ?

My level 3 will altitude will be about 30,000ft, acceleration of 24,000 ft /sec/sec  and Velocity at 2,100 ft/ sec

2) would I improve my chances of keeping my signal between my transmitter  on the ARTs Telemetry system with a directional antenna ?

I hope I can find people that have flown it to heights similar, and similar velocities and acceleration to tell me how it worked for them. I will have a Waltson on board as well- but it sure is nice to have a GPS reading, plug it into my hand held GPS and walk straight to the rocket.

Hi Brian,
When you say lost connection do you mean the 900mhz radios lost connection or the GPS did?

for all my ARTS GPS telemetry work I used the GPS mouse mounted on the outside of the parachute cannon covered with duct tape to hold it on and got GPS data almost always in all parts of flight.

I have never had a failure of the 900mhz radio system or a loss of the 900mhz link, but you must not just set it on a table or tailgate. It needs good Line of sight.

I alway put mine on top of my truck roof or a trailer roof and use a long rs-232 cable to the laptop inside the truck or trialer.

You can also get 900mhz gain antennas for the receiver if you plan really really high flights. Unless your L3 is going beyound 3 miles, gain antennas really are not needed. Gain antennas need pointed at the device in flight.

Jody,

 

The "rest of the process" depends on what equipment you have.

 

If you just need to go find the rocket, that is you are just interested in
GPS tracking, then ExpertGPS is probably the best way to go. You can
pre-download, at home, all of the maps for the area you will be in. Then use
the Tx-900g in GPS mode and let ExpertGPS record the data, plot tracks and
waypoints, and download them to your eTrex. This is exactly the way I
typically use the system with my eTrex Vista.

 

ExpertGPS can also write .gpx files that can be directly loaded into Google
Earth for display.When loading a .gpx into Google Earth, don't forget to
uncheck the "Adjust altitudes to ground height" box, otherwise Google Earth
will make all of the waypoints on the ground.

 

Thanks,

Erik

When you say "Lost connection", what do you mean? Did the radio link go
away, or you lost GPS data?

 

We've flown the telem system to similar heights, and higher. You need a good
directional antenna, usually a good yagi will suffice, to get these ranges.

 

Also, using the system in GPS mode is best if all you want is GPS tracking.

 

Thanks,

Erik

Upon Further review - Thank god for instant replay!

I reviewed all 3 log files-

I believe that the flight that stopped recording at the 2500 ft, It most 
likely was a user errror which stopped the program? - Or Stopped the logging 
for sure. The telem and GPS light were still green

The flight that the last altitude reading was at 98 ft - still had Tel and 
GPS green lights - and the third flight logged all the way to the ground.... 
So with that said - probably worked just fine!

But this brings me back to the higher flights that I have planned for my 
Level 3.

Art, you talk of 3 miles- works just fine with no additional changes other 
than a good line of site - so getting it up in the air higher than the 
Table. Is that the experience of most?

My level 3 flight will be going closer to 6 miles. Any recommendations?

Hi Brian,
When you say lost connection do you mean the 900mhz radios lost connection 
or the GPS did?

for all my ARTS GPS telemetry work I used the GPS mouse mounted on the 
outside of the parachute cannon covered with duct tape to hold it on and got 
GPS data almost always in all parts of flight.

I have never had a failure of the 900mhz radio system or a loss of the 
900mhz link, but you must not just set it on a table or tailgate. It needs 
good Line of sight.

I alway put mine on top of my truck roof or a trailer roof and use a long 
rs-232 cable to the laptop inside the truck or trialer.

You can also get 900mhz gain antennas for the receiver if you plan really 
really high flights. Unless your L3 is going beyound 3 miles, gain antennas 
really are not needed. Gain antennas need pointed at the device in flight.

Brian,

If you are just looking for GPS tracking, I would recommend putting the
transmitter in the nosecone or somewhere far away from the rest of the
electronics and metal. This will also help with GPS reception, as the sky
will not be blocked by all of the recovery gear typically surrounding an
electronics bay in the center of a rocket.

I would recommend using GPS mode, since it is character based and not
packet-based (ie you can receive parts of messages and not lose the whole
message). This is especially useful for spotty reception, you can look at
the logs and see the partial messages with your eyes.

I would also recommend getting a directional antenna. For 6 miles you do not
need a really high gain antenna, but a directional one would surely help.

Thanks,
Erik

How would I use a directional or Yagi antenna:

Do you have any examples - How do you connect to the ARTs telemetry 
receiver - etc?

Any help you can provide would be greatly appreciated.

Thanks -

Hi Brian, for ~31,000 feet I would get a good 900mhz yagi antenna to point at the rocket.

I have two Arts 2 Flight Computers. Both came with Data Analyser 1.6.1.

The first one has been working fine for over one year (multiple successful
flights).

The latest, recently received will not communicate with two of my PCs using
DataAnalyser 1.6.1

This item is fresh out of the package.

It remains in flight mode no matter what I do.

However it appears to respond correctly using Profile 1 with all ematches
connected.

 

Troubleshooted as follows:

Tried with two PCs and with two separate connection cables

Tried Hyperterminal connection with both PCs at 9600 8N1 no flow control

Tried Hyperterminal connection with both PCs at 38.4K 8N1

But unable to signal it with "z" to come out of flight mode.

Used multiple carriage returns as described on your web site FAQs. Is it
safe to use in this condition? 

 

I am running out of time for a swap out and have worn myself ragged with
diagnostics.

Is it safe to use for rocket recovery in this condition?

Do you have any other suggestions?

Graydon,

 

The ARTS2 is safe to use even if it cannot communicate with a PC. It comes
pre-configured.

 

However, it should communicate, and should be replaced if you somehow
received a defective unit. Can you ship it to me to take a look at it?

 

Thanks,

Erik

When is the ARTS family of altimeters going to the USB route of connecting to a computer?  I have a new computer with no little gizmos on the back or front that would hook up to the connector supplied with the altimeter.  My last computer (bought in 2005) had no such gizmos either.  I purchased 4 different USB to gizmo adapters and none of them worked or could be made to work even after working very hard with Erik to configure the little devils [thanks Erik for trying so hard!].

I had an old computer in the attic that ran Windows 95 and had the correct gizmo on the back.  I took that computer to work (not enough room at home) and installed it under a bench near my lab.  After a launch I take the ARTs's to work and download the data there and bring it home.  There's got to be a better way!

I realize that my description of little 9-pin gizmos instead of the correct name, and the fact that I have no idea of what a com port is, marks me as computer illiterate, and that a convincing argument could be constructed that I am just not computer savvy enough to have a right to own an ARTS unit.  However, a counter-argument could be constructed that would state that a company offering a product to the general public should make an effort to make that product usable for most of the intended market.

Please don't tell me to buy another "USB to gizmo" adapter, I'm really very, very tired of that approach.

Actually, the gizmo (RS-232) is the best ever COM.  I hate to see them go
away.  USB has whole host of issues in my 8 years of dealing with it
(special drivers and stuff).  If I were flying to Mars, I would want my
systems communicating via RS-232.  USB was and is still flaky.  I spent two
hours this evening figuring out which pseudo-COM port (USB) would
communicate with my new ARTS Telemetry system.  It is USB.  Not the fault of
the ARTS system, my laptop was giving issues.  On the ARTS altimeter, I have
never had a connection issue with the RS-232.
 
Erik, et al., - Please leave us with both options in the future!
 
Alan you should hang on to that soon to be collectors or artifact item
computer.  
 
"They will pry my RS-232 from my cold, dead hands" - or something like that.
Yeah, I am old.

Hi Alan,

 

Sounds like a problem with your computer or an operator error. The little
gizmo you?re talking about is an RS-232 serial port which has been obsolete
on most new computers (general ones at least) for the last ? decade. 

>From a user perspective, adding USB to ARTS2 would  (most likely) still be a
serial connection, only with a  different connector.  So, really, adding a
USB connection to the ARTS2 would only save you the cost of a USB-to-serial
converter (about $20). If you look at what it would cost Eric to get a USB
device and vendor ID, develop the firmware, go through certification of a
USB compliant device to put the logo on the unit, and then add the cost of
the USB to the ARTS2, I doubt anyone would pay for the extra cost. Then, it
would take Eric a while to get the money back, and most users wouldn?t have
any new functionality other than a shorter length of cable.  How do I know?
I?ve developed USB Device Controller (UDC) firmware for a few chipsets.

 

 I am sorry you don?t like the idea of buying a USB-to-serial adapter, the
maker of which, should be a 

well known manufacturer like Belkin, IOPort, or the likes, but if you have
tried these or other units,

and you are sure that you installed the USB->Serial driver, selected a new
COM port from DataAnalyzer,

connected the the serial port to the ARTS2 BEFORE YOU TURN ON THE UNIT, and
you still can?t connect,

it?s likely your serial port suffered from Electrostatic Discharge (ESD)
damage, which happens if you

mishandle your hardware (e.g. shock it like you get a static shock when
wearing a wool sweater). 

 

Here?s what I would do:



- Goto Control Panel->System->Device Manager

                - Verify the USB->Serial connector is attached

                - Verify the COM port setting is one which you have used or
has shown up in DataAnalyzer

- Open DataAnalyzer

- Select that COM port

- Connect to ARTS2 serial cable adapter

- Turn on ARTS2

- Select Altimeter->Configuration

 

You should connect and be able to configure the unit.

 

Thanks, and let me know what you find out.

 

-James

I use this adapter on a Windows Vista 64 bit system to access my ARTS2. My friend used it with his Windows XP system this past weekend and it worked on that as well. 

Not sure why you're having a problem but my understanding about USB adapters are that the quality of the drivers makes the difference. The .ini file may also have to be changed to work with the altimeter as well. See previous posts to this forum for how to do it.

The HP dc5800 & dc5850 & Z400's have a serial port, and some either have
two, or the option to add a second one.

Also, Siig boards for adding a few ports to a PC.

Serial ports are not a common as they were in the past, but they haven't
been discontinued.

For Notebook PCs with only USB ports, it may also be possible to buy a PCMIA card with RS232 serial port features.

from the book "USB COMPLETE"....
The conventional RS232/485/422 9 and 25 pin interfaces could always
connect to simple circuits with very basic protocols. But with USB now,
applications can't just read and write to port addresses and devices
can't just present a series of inputs and outputs to read and write to
directly.

I myself would pay more for a ARTS that did have a USB FIRMWARE device ID and certified driver. 
?
I've used the belkin interface adapter and it's a crap shoot, my solution is to grab old laptops when work is recyling them.

I use this adapter on a Windows Vista 64 bit system to access my ARTS2. My friend used it with his Windows XP system this past weekend and it worked on that as well. 

Not sure why you're having a problem but my understanding about USB adapters are that the quality of the drivers makes the difference. The .ini file may also have to be changed to work with the altimeter as well. See previous posts to this forum for how to do it.

The PC world did the industrial working world a great disservice by dropping the conventional RS232 serial port from PCs.

Approximately 95% of the industrial devices we connect to the the electrical and oil and gas industry still use RS232 9pin connections. For a deeper understanding of what was lost when moving to the USB port please see the following.

Yes... I love the desktop PC because of the many legacy compatible options.
It's the Notebook PCs that are the challenge, e.g., RTU, PLC programmers and
others who must work at remote site locations with light equipment on
battery power. This includes those needing to dowload flight computer data
at the launch site.

In any case I just confirmed with our automation department that they are no
longer having as many problems when using their Netgear USB/RS232
converters.

Subject: [ARTS] Rocket in the Ocean ?
Message-ID: <0KLP003TWU2XVQN0@vms173015.mailsrvcs.net>

 
I have been walking around and driving around with the new telemetry system
(a kid with a new toy).  RadioRx is a good thing as it is easy to convert
the bin file to gpx for ExpertGPS or Google Earth.  However, when I convert
the bin file to gpx and open in ExpertGPS, the rocket is out in the middle
of the Atlantic.  The launch pad is my home office.  The 900 Mhz Xmitter /
receiver are impressive given a major lack of line-of-site in a crowded
residential area and through the walls of the house.
 
Of course I did not really fly and the RadioRx stays in "on pad" mode since
I can't really simulate a launch.  So the question if anyone can help is:
 
1. Does RadioRx need to see the flight completed before it stores a valid
waypoint at the final resting spot?  Or is operator error at play here?
 
2. My 30 day trial is almost over for ExpertGPS - Does anyone know of or use
a good alternate I should evaluate before buying?

Jody,

 

1 - RadioRx, before launch, is updating what it believes is the Launch Pad
location. Think turning on the telemetry system then walking out to the pad.
Once liftoff is detected, RadioRx will record the last position before
liftoff as the "LaunchPad" waypoint, and start recording the flight data was
a new track. I think you are seeing your house as the launch pad, then 0 deg
lat 0 deg lon (the middle of the Atlantic) as the rocket's final location,
since liftoff was never detected.

 

2 - ExpertGPS is one of the best programs, since it can download all of the
map images and store them locally on your computer for use in the field. No
constant connection required.

 

Thanks,

Erik

I agree with y'all. USB is nice for hard drives and such, but you can't beat
the simplicity and reliability of RS232 for dependable connections.

 

HyperTerminal makes an excellent debugger in these cases as well.

 

I'm afraid USB is here to stay, and I'll do my best to accommodate it, but
like on the new RX-900, RS232 is still an option!   I hate dealing with USB
drivers. And the USB-whatever adapters are a nightmare just due to the fact
that so many of them do not work well.

 

Oh well. Enough of that.

 

I'll always be here to help anyone with a communications problem.

 

Thanks,

Erik

Actually, the gizmo (RS-232) is the best ever COM.  I hate to see them go
away.  USB has whole host of issues in my 8 years of dealing with it
(special drivers and stuff).  If I were flying to Mars, I would want my
systems communicating via RS-232.  USB was and is still flaky.  I spent two
hours this evening figuring out which pseudo-COM port (USB) would
communicate with my new ARTS Telemetry system.  It is USB.  Not the fault of
the ARTS system, my laptop was giving issues.  On the ARTS altimeter, I have
never had a connection issue with the RS-232.

 

Erik, et al., - Please leave us with both options in the future!

 

Alan you should hang on to that soon to be collectors or artifact item

Yeah, I am old.

When is the ARTS family of altimeters going to the USB route of connecting
to a computer?  I have a new computer with no little gizmos on the back or
front that would hook up to the connector supplied with the altimeter.  My
last computer (bought in 2005) had no such gizmos either.  I purchased 4
different USB to gizmo adapters and none of them worked or could be made to
work even after working very hard with Erik to configure the little devils
[thanks Erik for trying so hard!].

 

I had an old computer in the attic that ran Windows 95 and had the correct
gizmo on the back.  I took that computer to work (not enough room at home)
and installed it under a bench near my lab.  After a launch I take the
ARTs's to work and download the data there and bring it home.  There's got
to be a better way!

 

I realize that my description of little 9-pin gizmos instead of the correct
name, and the fact that I have no idea of what a com port is, marks me as
computer illiterate, and that a convincing argument could be constructed
that I am just not computer savvy enough to have a right to own an ARTS
unit.  However, a counter-argument could be constructed that would state
that a company offering a product to the general public should make an
effort to make that product usable for most of the intended market.

 

Please don't tell me to buy another "USB to gizmo" adapter, I'm really very,
very tired of that approach.

James,

 

You can tell ExpertGPS to download maps by changing to the "Retrieve Maps
Tool" tool (from the main menu, select Map->Select Map Tool->Retrieve Maps
Tool). Draw a box around the area you are interested in, select the map
types and resolutions in the box that pops up, and then ExpertGPS will
download all of the map files to your machine. 

 

Thanks,

Erik

Hi Erik,

 

How do you get ExpertGPS to download all of your maps and store them on your
HDD?
When I go out to blackrock, this doesn't happen.

 

Maybe I have an old version of it ... what version do you have?

Thanks!

the bin file to gpx and open in ExpertGPS, the rocket is out in the middle
of the Atlantic.  The launch pad is my home office.  The 900 Mhz Xmitter /
receiver are impressive given a major lack of line-of-site in a crowded
residential area and through the walls of the house.

 

Of course I did not really fly and the RadioRx stays in "on pad" mode since
I can't really simulate a launch.  So the question if anyone can help is:

 

1. Does RadioRx need to see the flight completed before it stores a valid
waypoint at the final resting spot?  Or is operator error at play here?

 

2. My 30 day trial is almost over for ExpertGPS - Does anyone know of or use
a good alternate I should evaluate before buying?

Yes, you can edit the .gpx file. Open the file with your favorite text
editor and just delete the waypoints you do not want.

 

Is the problem that all of your waypoints on the ground in Google Earth?
Google Earth, by default, sets all waypoints to ground level. When you load
the .gpx into Earth, uncheck the "Adjust altitudes to ground height" box.

 



 

Thanks,

Erik

Erik,

Yes, sometimes I also get strange points in the GPS data, around or after
apogee descending. The points usually are together but then there are some
intermittent points that are like miles away. I guess it looses GPS lock
sometimes and then there are some strange points in the data.
I wonder if I could edit the bin (or gpx) file to remove those points, kinda
like smoothing out the data from noise.

I believe I was able at some point in time to use the new RadioRx (I still
have to use the old when I record flight data from my old Ozark/GPS) to 
import my old bin file and then save a gpx file. Then I used Google Earth
(hey, it's free) to import the gpx into the map. The new Google Earth 
also has some cool 3D rotation but I was not able to get my GPS data with
the recorded altitude into the 3D Google. 
I will see if I can get this done.

THX, John

Jody,

 

1 - RadioRx, before launch, is updating what it believes is the Launch Pad
location. Think turning on the telemetry system then walking out to the pad.
Once liftoff is detected, RadioRx will record the last position before
liftoff as the "LaunchPad" waypoint, and start recording the flight data was
a new track. I think you are seeing your house as the launch pad, the n 0
deg lat 0 deg lon (the middle of the Atlantic) as the rocket's final
location, since liftoff was never detected.

 

2 - ExpertGPS is one of the best programs, since it can download all of the
map images and store them locally on your computer for use in the field. No
constant connection required.

 

Thanks,

Erik

James,

 

You can tell ExpertGPS to download maps by changing to the "Retrieve Maps
Tool" tool (from the main menu, select Map->Select Map Tool->Retrieve Maps
Tool). Draw a box around the area you are interested in, select the map
types and resolutions in the box that pops up, and then ExpertGPS will
download all of the map files to your machine. 

 

Thanks,

Erik

Hi Erik,

 

How do you get ExpertGPS to download all of your maps and store them on your
HDD?
When I go out to blackrock, this doesn't happen.

 

Maybe I have an old version of it ... what version do you have?

Thanks!

Message-ID: <4A43C5A2.2060702@lokiresearch.com>

I just received a fresh batch of ARTS2 and I'm going to make an offer to
those on the ARTS user list.

You may purchase a bare ARTS2, just the ARTS, no cable, no CD, no
instruction card, for $150 (regular price is $189.99).

The ARTS has not been available at this low a price since 2004!  This is
a great way to save if you are already an ARTS flier and don't need
additional cables, etc.

To take advantage of this offer, please place an order for an ARTS2
through the Loki Research web store at http://www.lokiresearch.com and
make a note in the comments section that you want the "bare ARTS discount".

Thanks!

Message-ID: <4a4412b7.04c2f10a.05a5.764c@mx.google.com>

I am new to high-power, and new to this electronics stuff (for rockets). So
on my limited funding, I have to plan closely and make every dime count.
(hey, I bought an arts2)

 

I am planning on getting a laptop, figured I would search the repair shops
for a relic (so I can eliminate this issue), I don't like any of the new
windows... so 2000 or XP is fine by me for my rocket stuff...

 

So. my first choice is to find relic pc.

Second would be the 20.00 adapter.

If either of those don't work maybe this thing:

 

http://www.shopfloorautomations.com/serial_laptop_pcmcia.php

 

These guys make automation equipment. Perhaps this card is the answer to
Serial to USB conversion. Just put a serial port on your computer? Lot's of
CNC like RS232. 

Less than 75.00 to 110.00 would defiantly be my last ditch effort. but, I
don't have any experience with it yet.

 

Does anyone have the dataAnalyzer loaded on XP professional 64bit?(useless)
I am not having any luck.

I manage network equipment for a living, and serial to usb adapters are a lifeblood.   I've got enough of them stashed at clients now that even if I forget one in my bag, I've got one everywhere.

Clay-

I'm not sure which version of DataAnalyzer you are working with, but try this one http://www.lokiresearch.com/Programs/DA1.7-CD Contents.zip   It has a newer installer that Erik says works with 64bit Vista.

Also, while some people have had some troubles with the USB to serial converters, it is a fraction of the people who try them.  Of those who do have trouble, the recent post from Alan was the first I've ever heard that did not get it working eventually.  Personally, I have used at least three different USB to serial converters that all worked without much hassle (all on WinXP systems).

In short, I would certainly give the $20 adapter a shot.

-Jeff
