We are having some issues with the antenna tracking- the dish is not following the payloads and is not pointing in the right direction. It also has weird directional data populated in the ground station data section: the lat, long, and elevation are correct, but it will say it is pointing north, or at some other degree direction that is incorrect. We have tried recalibrating the IMU (usually we do get the "3" for accel, gyro, and mag upon startup, but occasionally get "0" for one or more fields), restarting the system, pointing the ground station in different directions, recalibrating the center bearing, etc, and are still unable to get an accurate lock.
After looking through other posts and reviewing the initial build instructions, we believe the root of our issue may be that the servos are no longer zeroed. The dish has been physically rotated a lot so we are wondering if this could contribute to the bad directional lock. Additionally, today the elevation servo was making a faint humming noise when connected.
Has anyone else taken their ground station apart to re-zero the servos? If we did try this, are there any potential problems we should be aware of, and will re- zeroing the servos possibly help our ground station point in the right direction? Any input or other solution ideas is greatly appreciated!
