Experiments With Two-Satellite Instantaneous Attitude Determination

Frank van Graas, Kevin Dutton

Abstract:	A technique is introduced to perform instantaneous satellite-based attitude and heading determination using two satellites. Two key elements of this technique are the use a calibration signal to remove the clock offset between the satellite receivers in combination with the use of a short baseline of length less than (l/2-e), where l is the wavelength of the received carrier signal from the satellites, and e represents the largest expected error in the single difference carrier phase measurements. Performance results are provided for a single baseline in a high-multipath environment. The two-satellite solution is compared with a standard double difference solution for the pitch and heading angles of the single baseline.
