TRAIM Availability Algorithms and Analysis for LEOs Based on GNSS
Abstract TRAIM availability models and algorithms are discussed, and the simulation platform is constructed based on STK and MATLAB software. The simulation of the four different LEOs (500 km, 650 km, 800 km and 1 400 km), based on observations of GPS and BDS, shows that the combined method can achieve the TRAIM availability probability of 99.1% when the threshold of the TRAIM is 100 ns, indicating that TRAIM availability based on BDS and GPS can meet the demand of time synchronization integrity for LEOs.
