Impact Analysis of CNES Real-Time and Archival Satellite Orbit/Clock Offset Products on BDS PPP
Abstract From the perspective of CNES BDS real-time PPP users, this paper studies the orbit/clock difference between the BDS real-time and archival products for 10 consecutive days, and analyzes their impacts on BDS PPP. The results show that the orbit difference between these two products is below 1 mm, but the clock difference reaches ±0.1 ns. These two products are applied to BDS static PPP of four IGS MGEX stations. It is found that the difference between the two products can impact the PPP convergence speed, and the positioning accuracy difference after convergence can reach 3 cm. Therefore, we cannot ignore the difference between CNES real-time and archival orbit/clock products.
