Modelling and Simulation of Vehicle with INS/GPS Navigation

QU Wei-dong

Abstract

In order to locate the vehicle accurately and realize the function of navigation,the two kinds of commonly used navigating and positioning technology—the GPS and the inertial navigation technology are combined.A way of simulation for the INS/GPS integration navigation system is introduced.The navigation system requirement for precision is not high,so the low-cost gyroscopes and accelerometers can be used as the inertial navigation system measurement devices.The INS/GPS navigation system uses the position and velocity combination pattern.Also the error comparison among INS,GPS and INS/GPS is given.Analysis shows that the precision of integrated navigation system is the highest of all.
