I tweaked some things :
- Changed setting in the neo 6M GPS (pedestrian mode for example)
- Added HDOP GPS base value on the OLED while not tracking
- Switched IR control to another µC, a mini pro 5V wired to the last serial output available on the mega.
It allow to send the command start / stop / zoom that takes 90ms without slowing the MEGA that is making the GPS computation.
- Ordered 10HZ neo 8 GPS
I tested 3 flight with 30min idle positionning to be sure that the FIX is solid, however the HDOP value from tinygps++ was never belove 95 .. I need to contact the guy that did it to ask some questions.
It worked well !! I need to upload the video on youtube, this time the test subject was my EXTRA 300 78" (2m) from Extreme flight.
It showed also that I need to tune the tilt angle computed from altitude.
