The mathematical model and simulation of north-finder based on rate biased RLG
In this paper, the basic principles of north-finder based on rate biased ring laser gyroscope (RLG), the mathematical model and the least square (LS) arithmetic are introduced. The measurement error of RLG (scale factor instability, bias instability, and random angle walk) and the angle measurement error of the platform are the major errors of the north-finder. Simulation analysis is performed to get their influence to the precision of the north-finder. Finally, an experiment is performed to test the mathematical model and the LS arithmetic.
