  • With the advent of Galileo and Chi-
    nese Compass, GNSS navigation technologies will develop
    rapidly. However, as the number of navigation satellites
    in view will increase, the fault probability will rise. This
    paper calculates the multi-fault risk of multi-constellation
    satellite navigation system in terms of MOPS. It is high-
    lighted that the probability of either one-fault or double-
    faults is higher than integrity requirement. The paper also
    describes a snap-shot ramose RAIM technology to protect
    civil aviation users in multiple-fault case. In this condition,
    a series of FDE calculation is adopted to separate satel-
    lites in sight into several groups. Therefore the problem
    will transform into several single-fault case, which current
    RAIM can solve. Simulation results verify that this tech-
    nique is proper to solve both single-fault and double-fault
    problem of civil aviation caused by application of multi-
    constellation GNSS.
