Principle and design of a pseudolite system

There are more and more relationships between human beings and satellite navigation systems.However,some interferences hinder satellite navigation system from functioning well at all times.This paper introduces an implemented GPS navigation system——pseudolite system.This paper mainly discusses the background,principle and future of pseudolite system.Also,in order to solve a general problem that most pseudolite systems are of high cost,this paper gives out a kind of pseudolite transmitter system which is of lower cost,lower power,high reliability for choice.
