Attitude Determination Using Ambiguous GNSS Phase Measurements and Absolute Angular Rate Measurements

Аннотация

Integration of a multiantenna GNSS receiver and inertial sensors (gyroscopes) is proposed to determine attitude parameters using GNSS phase measurements, containing integer ambiguity, and measurements of the absolute rotation rate of a moving vehicle. The potential accuracy of the proposed technology is estimated based on the simulation and full-scale tests. The implementation of the proposed approach is considered.
