Testing a New GPS-Based Attitude Determination Sensor

Sponsored by internal Cornell funds

Project Participants: Mark L. Psiaki (PI) and Warren Scott

This research is developing a prototype to test a new GPS attitude determination sensor. The sensor uses a single L1 antenna mounted off-axis on a spinning turntable. The spin of the turntable causes the GPS carrier signal to have an FM modulation with the modulation frequency equal to the spin rate of the turntable.  The amplitude and phase of the modulation can be used to determine the direction vector to the a GPS satellite in turntable coordinates.
