Network parameter design of PINS azimuth fine alignment

Initial alignment is one of the key technologies of inertial navigation system, but in moorage, the external disturbance will impair the accuracy in the initial alignment of inertial navigation systems. The purpose of this paper is to design a network parameter of initial alignment which has the capacity of resisting disturbance, analyzing the design method of the alignment loop network parameter, and developing a software to design and verify the network parameter of azimuth fine alignment, automatically. Also, an example is designed to verify the correctness of the software. Computer simulation results indicate that the network parameter is designed and verified by the software automatically according to the requirement of the parameter.
