摘要
Abstract
To solve the parameter estimation of spinning projectile SINS/GPS system,a generalized error model was established. The output correction filter was utilized to estimate the errors of measurement,and then a new filter was proposed by piecewise integrating the output correction filter with the feedback correction filter. Schematic diagrams of the output correction filter and the feedback correction filter,and the flow chart of the piecewise-integrated filter were also provided. According to the loose integrated model of SINS/GPS system, the simulation was carried out by taking the 6DOF simulation data of certain spinning projectile for instance. The numerical simulation results show that the proposed piecewise-integrated Kalman filter can improve the estimation accuracy. The results can provide an effective solution to accurately measuring the motion parameters of the spinning projectile.关键词
