Abstract
Considering the difficulty of implementation on global integrity of COMPASS for the constrain of global deployment of monitor station, this paper proposed a principle design for global integrity of COMPASS based on combination of pace and ground, by managing Signal-in-Space Accuracy (SISA) and monitoring the integrity anomaly of satellite. An implementation scheme of integrity monitoring of satellite clock and navigation signal onboard is provided, with theory analysis and simulation study of integrity monitor in case of malfunction of clock error, clock rate and clock acceleration, also the distorted of PN code. Simulation results indicated that the integrity monitor of step and ramp error of clock can be realized by using the method based on the difference of main-backup clock phase difference and Inter-Satellite Ranging (ISR), and the integrity monitor of distorted PN code can be realized by using SQM2b algorithm.
