| Abstract: | Based on the measured data, this paper aims at the airworthiness of the Advanced Receiver Autonomous Integrity Monitoring (ARAIM) algorithm, and tests the performance of GPS／BDS ARAIM algorithm fault detection and elimination and the performance of availability prediction. The test results are as follows. The performance of ARAIM algorithm fault detection and elimination is good under the GPS／BDS combined system, and the efficiency of correct detection and elimination of step faults greater than 100m reaches 99.9％. In single point, the availability of ARAIM under the GPS／BDS combined system is good and fully meets the integrity performance requirements of the LPV-200. The availability coverage in China reaches 99％. The availability coverage in the world reaches more than 90％. So, the performance of GPS/BDS ARAIM algorithm is good. |
