This is my first post on that forum, so first : many congratulations to those who are concerned about the development of this really amazing board ! I didn't get one at the moment, but as soon magnetometer + hotel will be available in stock, I'll do.
I had a look on the APM code, but something is not clear for me. The way the soft is fixing the yaw angle is my concern : I understood there is 2 ways for that in the code ?
- first is direct reading from magnetometer
- second is indirect fixing by GPS vector
But they are separate ways, is that true ?
I don't know if it's possible or already done so here is my question :
- with magnetomoter and pitot tube relative wind data (optional gyro + accel data for the pitch for 3D computing) you can have the real vector of the aircraft on the yaw angle,
- with the GPS you get real vector relative to the ground (optional more accuracy with the pressure sensor for the altitude)
With that informations, we can compute the real vector of the wind (optional in 3D), which is a real important information for the fly : to know if your plane is able or not to go in front of the wind (optionnal detecting thermals strength to climb more easily) ?
Perhaps it's already done, I don't know ?
What do you thing about ?
Many thanks again !
