ABSTRACT
In order to improve the effect of trajectory control, it is necessary to enhance the accuracy of exterior trajectory measurement. Based on the particle dynamics model of the guided projectiles, various error sources in GPS positioning are discussed, and the mathematical model of tropospheric delay error is derived. The simulation of the GPS information received by the guided projectiles during flight is simulated by the Matlab. The impact of tropospheric delay error on the positioning error of GPS navigation trajectory is simulated. The research results provide some technical support for the error analysis of the GPS exterior trajectory measurement.
