摘　　要：在游动方位角坐标系下建立了方位大失准角条件下的SINS初始对准误差模型。在静基座下验证了该误差模型在方位大失准角情况下的滤波效果,比较分析了不同方位失准角的滤波收敛情况,并与线性模型进行滤波比较。最后,将该模型用于动基座的初始对准。静基座和动基座下的初始对准结果表明所提出的SINS误差模型是正确有效的。The navigation error model is established to provide align capability for SINS in the wander frame, while not requiring an initial heading estimation. The filtering algorithm by using the error model is tested for both small misalignment angles and several different large azimuth misalignments with comparing with linear filter model. At last, the error model is also tested in swaying base. The simulation results in both ground and swaying base alignment show that the correctness and effectiveness of the model.
