摘要
研究了一种利用GPS载波相位三差观测信息的多天线GPS/INS组合定姿算法,其中包含一个基于惯性测量信息的GPS载波相位周跳检测算法。最后,通过仿真分析验证了该组合算法可以有效提高定姿精度,同时具有较好的稳定性。
Based on the triple difference carrier phase observables, a GPS/INS integration algorithm for attitude determination is studied. The proposed integration system also contains a cycle slip detection algorithm, in which inertial information is utilized to detect cycle slip. Some computer simulations are performed to verify the proposed integration system. The results show that accurate and reliable navigation solution can be gained.
