Simulation of INS/CNS/GPS Integrated Navigation

Zhikai Jia

Open publisher page 11 citations

Abstract

This paper investigates the theory and characteristics of INS/CNS/GPS integrated navigation system and simulates the system. The author present a new method using the error-angles of the platform, the position differences of INS and GPS, the velocity differences of INS and GPS as measurements. The error-angles of the platform, the error of the gyros, the accelerators and other navigation parameters can be estimated using Kalman filter. The results of simulation show that the integrated navigation system improves the precision of navigation system greatly by correcting the platform and eliminating the error of navigation parameters.
