Abstract In order to improve GNSS integrity, a new integrity monitoring method of GNSS aided by INS with considering the phase Doppler smoothing code is proposed. In this algorithm, by the use of phase Doppler smoothing code to reduce the random error, the parity vector can be obtained by using measurement derived from INS and GNSS for fault detection and isolation. The simulative results show that the integrity monitoring method of GNSS aided by INS can increase the fault detection rate, when considering the phase Doppler smoothing code the performance improvement is more significant.
