The present disclosure provides a compliance test method and system for Receiver Autonomous Integrity Monitoring (RAIM) performance of a BeiDou navigation satellite system (BDS) airborne equipment. The method includes: acquiring BDS almanac parameters and test parameters (101); determining whether the satellites are visible according to the almanac parameters and the test parameters (102); acquiring space-time points when the satellites are visible (103); computing the Horizontal Protection Limit (HPL) of each of the space-time points (104); selecting marginal geometries space-time points according to the HPL (105); test the space-time points and the marginal geometries space-time points to obtain a first test result (106); acquiring the configuration parameters and the BDS almanac of the satellite navigation vector signal generator for the marginal geometries space-time points (107); decoding the configuration parameters and the BDS almanac to obtain the number of visible satellites (108); determining whether the number of visible satellites is greater than a threshold (109); testing the marginal geometries space-time points to obtain the second test result if yes (110); and determining whether the first test result is matched with the second test result (111). The method can check whether the BDS airborne equipment meets airworthiness requirements.
