Abstract: GPS integrity monitoring problem must be solved in GPS navigation.This paper discusses in detail the FDI and FR problems with parity vector method using the likelihood rate's point of view.At last,sudden failures and soft failures with GPS satellites are considered in simulations respectively,and the results show the reasonableness of the parity vector method.This method provides rationale basis for the implementation of RAIM.
