Kalman filtering of coordinates determination for local positioning systems mobile objects

Abstract

The article is devoted to the study of Kalmanfiltering errors of the measured radio navigation parameters into the coordinates and elements of the objects movement in relation to the ground-based radio navigation system of local positioning. The stationary state of the mobile station, its uniform rectilinear and uniformly accelerated movement are considered. The use of optimal estimation of the Kalman filter allows reducing the standard deviation of coordinates by 1.5-3 times for the considered mobile station trajectory.
