In order to meet the integrity requirement of high accuracy positioning like precision approach CAT III and carrier-based aircraft landing, a MHSS (Multiple Hypothesis Separation Solution) based CRAIM algorithm is proposed in this paper. The integrity risk and continuity risk of each failure mode are optimized under the constraint condition to calculate the optimal vertical protection level (VPL) threshold, and the relationships between VPL and priori probability of single satellite fault, maximum and nominal value of single-difference carrier phase measurement deviation are analyzed. The simulation results show that the proposed algorithm can provide a lower VPL and increase the availability of the system, VPL will be affected by the priori probability of satellite fault, maximum and nominal value of measurement deviation while the algorithm performance is relatively stable.
