    Hello,

    In /etc/modalai/voxl-px4.conf set GPS to NONE. Then set the PX4 parameters SYS_HAS_GPS, and SYS_HAS_MAG to 0. Set EKF2_MAG_TYPE to None. Set EKF2_GPS_CTRL to 0. This is when my GPS was broken.

    I was getting Preflight Fail: heading estimate not stable and Preflight Fail: Yaw estimate error

    How could I fix the error? Is there any calibration or anything else that needs to be done? I was looking at QGC and yaw seemed to move smoothly when i yawed so I don't know what the issue is. /mavros/local_position/odom seems to be properly providing the drone's pose as well, at least the position and yaw.

      @Nitin-Varma-Vegesna Are you using EKF2_EV_CTRL to supplement the GPS denial?
