I tested the latest antenna tracker version (V1) a few days ago. I first tried in baro mode and I get large pointing errors both in pitch and yaw, as shown in the video below. In GPS mode it appears there is a bit “more pointing recision” but the tracker is still not perfectly pointing to the copter, with deviation that can get to more than 10 degrees. The poiting error is not constant and I believe it is not due to the mechanical setup of the tracker itself.
I also join the log file for troubleshooting,
