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".

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.

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 &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.

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 No virus found in this incoming message.

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.

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. Jody Johnson -------------- next part -------------- An HTML attachment was scrubbed...

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.

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 (launch site). Anyone know of any other really good freeware for GPS tracking. Help me see the BIG picture on how to use this cool system. Maiden flight will be at LDRS 28. Thanks in advance for your help.

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. -------------- next part -------------- An HTML attachment was scrubbed...

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.

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.

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 (launch site). Anyone know of any other really good freeware for GPS tracking. Help me see the BIG picture on how to use this cool system. Maiden flight will be at LDRS 28. Thanks in advance for your help. Jody No virus found in this incoming message.

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.

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. No virus found in this incoming message.

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.

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 From: arts-bounces at lokiresearch.com [mailto:arts-bounces at lokiresearch.com] On Behalf Of Alan Whitmore Sent: Monday, June 22, 2009 7:15 PM To: arts at lokiresearch.com Subject: [ARTS] computer connections 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.

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.

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.

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.

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 open20in 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.

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.

Clay 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 -- Jeffrey S.
