Abstract:	The integrity is a major limitation for GNSS applying in these important applications fields. GNSS integrity is also extended to use in the other GNSS application fields. The parameters about integrity is also varied. A variety of integrity monitoring schemes have been proposed in a lot of literatures. Different parameters and terms are proposed in terms of the different application fields and research topics. It is necessary to rearrange a series of integrity monitoring parameters to evaluate the validity of these integrity monitoring schemes. Integrity is the measure of the trust that can be used for the correctness of the information supplied by the whole navigation system. To assess the integrity monitoring performances, we ought to consider both the electromagnetic environment and the technical capabilities of the receiver, besides the consistency derived from the solutions of Position, Velocity, Timing and Attitude (PVTA). According to the location and characteristics of the subject of integrity monitoring, a complete three levels GNSS integrity monitoring method based on corresponding theoretical analysis is proposed. And the construction of GNSS integrity monitoring assessment system is built. This paper promotes an extensive implication and the integrity monitoring performance parameters. It push forward integrity analysis from the solutions of PVTA to Baseband RAIM (BRAIM) and radio Frequency RAIM (FRAIM). It spreads the scope of navigation integrity application. This paper proposes a series of integrity monitoring parameters to evaluate validity these integrity monitoring schemes. This research does not only reinforce the understanding of integrity monitoring, but also enriches the investigation about the noise, interference and multipath to receiver.
