AHRS_COMP_BETA: AHRS Velocity Complementary Filter Beta Coefficient¶

This controls the time constant for the cross-over frequency used to fuse AHRS (airspeed and heading) and GPS data to estimate ground velocity. Time constant is 0.1/beta. A larger time constant will use GPS data less and a small time constant will use air data less.
