“…The ISLs refer to the effective expansion of the telemetry, tracking, and command (TT&C) and communications range of ground stations [4,5] by establishing communication and measurement links between satellites. On the one hand, measurements via ISLs can effectively improve orbit determination and time synchronization performance in GNSSs; on the other hand, ground stations can control satellites that cannot be directly linked to ground stations [6].…”

“…Among them, the correction methods for some error sources are relatively mature, such as the tropospheric delay correction and multipath and noise smoothing, but pseudorange bias correction has not been widely recognized. Although most of the error sources are as same as the Radio Navigation Satellite System (RNSS) [25], the indicator of the BDSBAS (H:1 m/1.5 m V:1.5 m/2 m) is more demanding then RNSS (3D:10 m). Therefore, we need to clarify the impact of these errors on the service.…”

“…Results showed that the three-dimensional root-mean-square error (3D RMS) of the BDS-2's one-day overlapping arc for MEO (and IGSO) and GEO were improved from 0.5 m and 3.0 m to 0.2 m and 1.0 m, respectively. Moreover, the BDS-3 orbit and clock determination is focused on the following three aspects: (1) analyses of the precision, accuracy, and quality of BDS-3 observations and products, respectively [14,15];…”

“…(2) assessment of the impact of introducing inter-satellite links on precise BDS-3 orbit and clock offset determination [14,16,17]; (3) stacking the satellite-ground link and satellite-to-satellite cross-link observations in BDS-3 orbit determination [18]. Similarly, the results indicate that the radial and along-track directions of one-day orbit overlapping (the discrepancy of arcs based on two adjacent orbit determination processes) were improved from 10.0 cm and 25.0 cm to 3.7 cm and 7.9 cm, respectively, and the frequency stability of theonboard clock also increased by more than 10 times for BDS-3 experimental satellites [15,19].…”
