I'll preface by saying that I'm not a C++ developer. There are multiple references to APM2/2.5 support for UART2 on the forum. Most references don't seem to come to conclusion. I think we have…Continue

If you are not using NMEA disregard.I recently discovered what I think is a parsing error for the NMEA lat/long decimal minutes in the latest version(s) of the GPS library. I found this when doing…Continue

I wanted to make a minor change to uncomment WITH_NMEA_MODE, run a GPS test in Mission Planner for Venus GPS (didn't get that far). I got compiler warnings with both 2.27 and 2.28 using both 022 and…Continue

On 5/18/12 North Texas Near Space (NTNS-2) achieved a maximum altitude of 87959 ft over a sparsely populated section of North Texas. The flight was…

I've just finished the build and will begin early full up integration testing in the next day or so on NTNS-2. This is a highly modified Stinger 64 with APM2. There are really 2 airframes. One is for flight testing, gain tuning, learning a little about APM2. I have to admit that there have been several issues. …

On 5/20/12 North Texas Near Space (NTNS) and Project Soar collaborated on a dual launch during the annular eclipse. Albuquerque was directly in path of the eclipse. The NTNS payload had most of the electronics that I had intended for a guided flight. That airframe is no more, but I have some data that I'd like to share with the group as a result. The dual launch was a great target of opportunity…

do you know what the max dynamic pressure you saw during your 101K flight? do you have velocity vs altitude data that is available to look at?

Hi Larry I finally got a chance to view your video of the 101k today I liked the release it dropped clean then spun down to the thicker air around 57k got control and started hunting for the way points. When I first seen it pull it's nose up and the sun come into view I knew the flight would be a success the further it descended the more solid it became right down the groove..It must have been quite a scramble to get from the launch to the landing area. you could poke around and maby get a grant to collect upper atmosphere air samples to look for various levels of ozone and such.Congradulations on the flight thanks for sharing it with me I will study it again in detail and see if any thing extra ordinary stands out Have a good Day!
