Integrating GLONASS with GPS for Drone Orientation Tracking.

In addition to position sensing, GPS receivers can be leveraged for orientation sensing too. We place multiple GPS receivers on drones and translate their relative positions into orientation. Such an orthogonal mode of orientation sensing provides failsafe under Inertial sensor failures – a primary cause of drone crashes today. This paper integrates GLONASS satellite measurements with GPS for enhancing the orientation accuracy.
