Multipath Mitigation Technique for GNSS Gyrocompass Using Phase Measurements

摘要

Abstract The paper focuses on the methods to reduce the satellite signal multipath effect on the accuracy of attitude parameters, in particular, the true heading, generated by the designed marine GNSS gyrocompass—INS/GNSS system with the single-axis rotation of the antenna and IMU units. Test results for the compass prototype model have been provided, with the artificial distortions created by the GNSS signal reflector.
