Navigation Error Estimation of Moving Platform Based on Non-Cooperative Targets
In response to the problem of low accuracy in position measurement of motion platforms,a non-cooperative target based navigation error estimation method for motion platforms is studied.The navigation error of the platform is es-tablished as a first-order time-varying model,and the motion parameters of the platform are solved.A linear model is used to fit the position measurement of different targets relative to different platforms.By comparing the differences in estimat-ing the same target motion parameters between the reference platform and other platforms,the navigation error param-eters of the platform are solved,and the platform motion parameters are corrected.Numerical simulations have demon-strated the effectiveness of the algorithm and analyzed the impact of measurement frequency on navigation error estima-tion accuracy and target positioning accuracy.
