Abstract:This paper first analyzed the data interruptions of RTS (real time service) products, and second carries on research into methods of repairing of these disruptions. According to statistics on the interval distribution of these data interruptions, the maximal repairable interval of 15 min is selected. Then, the data interruptions less than 15 min are repaired with different interpolation methods. The satellite orbit data interruptions are repaired using the common Lagrange interpolation with different orders. In order to explore the optimal solution, the satellite clock data interruptions are repaired with the Lagrange interpolation, cubic spline interpolation, linear interpolation and linear fitting, respectively. Finally, an experiment of simulative near real-time PPP on the IGS station is conducted using the repaired RTS orbit and clock products to verify the proposed method.
