I am using Ardupilot with XY sensors from FMA Copilot. I do not use a Z sensor. I mention that throttle is controlled directly from receiver (Ardupilotdoes not control throttle). I have shield V2 installed but I selected not to use airspeed sensor for these initial tests.
I use the latest Ardupilot firmware (Ardupilot 2.7).
Yesterday was a sunny day. I was flying and stabilization and fly_by_wire modes worked perfect.
Today is a rainy day; the sky is covered by clouds. I wend to the same airfield and the stabilization/fly_by_wire doesn't seem to work anymore.
I suspect the problem is represented by the thermopile's readings. I checked stabilzation on the ground and the elevons do not seem to move when I roll/pitch the airplane.
Probably one fix would be to get a Z sensor and use the entire setup with a Z sensor to do IR calibration on the fly for all-weather conditions. Since I do not have a Z sensor, what other fix do you recommend me to do?
What should I change in the code (IR variables?) in order to make it work in cloudy days when the sky is covered almost entirely with clouds.
I checked the IR conditions with an FMA copilot and I get minimum of temperature difference allowed for one to fly with a FMA copilot (the temperature difference observed by the FMAcopilot is converted in elevons twisting during calibration process).
Thanks!
