MODELING AND PARAMETERS ESTIMATION OF MARINE GUIDANCE INSTRUMENTATION SYSTEMATIC ERROR

Yao Jing Duan Xiaojun Zhou Haiyin (Department of Mathematics and System Science, Institute of Science, NUDT, Changsha, 410073 )  
The separation of guidance instrumentation systematic error (GISE) plays a vital role in the submarine launched missile precision analysis. The paper firstly illustrates various influence factors on trajectory data of a submarine launched missile, that is, the initial state when launching, such as the origin orientation and submarine initial velocity. Secondly, after considering GISE in the velocity region together with the initial errors, the paper finally constructs a nonlinear coefficient model of the marine-based GISE separation. Corresponding estimation algorithm and simulations are presented. Results show that both the model and the algorithm are feasible.
