Abstract

In recent years, there is a growing interest in GNSS (Global Navigation Satellite System) compass type attitude determination system. Multi-mode single epoch scheme is the point for the current research, since it is insensitive to cycle slips and it has a higher success rate. With this scheme, the coverage, integrity and availability can also be improved for the practical application. As a new type of compass, being different from the magnetic compass and gyrocompass, the correctness of resolved heading and elevation should be verified by internal fitting method or external fitting method. In this contribution, as one internal fitting method, the self-verification of GNSS multi-mode single epoch compass system is studied, based on the double collinear baselines with different lengths. Actual dynamic experiments based on L1/L2/B1 observations have been performed, the relative yaw and relative pitch are computed and the results verify the correctness of GNSS multi-mode single epoch compass system with the self-verification method.
