基于伪距/伪距率的组合导航系统仿真
Integrated Navigation System Simulation Based on Pseudo-Range/Pseudo-Range Rate
摘要
Abstract
In the research of the GPS/INS integrated navigation system, the researches based on position/velocity are relatively mature, but the researches based on pseudo-range/pseudo-rang rate are relatively less. In those mi-nor researches, most of them are about covariance, and the researches using the simulating and practical data are even less. In this paper, the tightly coupled navigation system based on pseudo-range/pseudo-rang rate was studied, the mathematic model was established and simulated using Matlab. Then the results was calculated us-ing this simulating data, and in the end the results was compared to that from the experiment based on the po-sition/velocity using the same simulating data. The simulation results show that the integrated navigation system based on the pseudorange/pseudorang rate could obtain a higher precision than that based on position/velocity.关键词
