“…In accordance with the studies of predecessors, the measurement noise of BDS-3 ISL is confirmed to be less than 10 cm [29]. Because of the more complex space environment in which the LEO constellation operates, we mainly adopt numerically larger 20 cm-level noise scheme in this study.…”

“…The topology of the ISL shows how the link is connected, which is closely related to the geometric structure of the range-measuring network and has a great impact on the results of orbit determination. Chinese BDS-3 uses such a link topology: as long as a pair of satellites are visible to each other, a link is established [29]. In the following text, this link topology is recorded as "all-connected."…”

“…Precise BDS-3 products of Wuhan University (WUM) [25] are used here. Although no exact precision of the WUM products is reported for BDS-3 satellites, previous research indicates that the average 3D orbit RMS is better than 20 cm [11][12][13], as there are still not many stations tracking BDS-3 satellites. Comparing with the 0.5-1.0 m level precision of broadcast ephemeris, WUM products would be sufficient to assess the SISRE of BDS broadcast ephemeris.…”

“…Many scholars have described the BDS-3 status and the main service function indexes [2][3][4][5][6], including the constellation design, service type, navigation signal system, space-time datum and orbit determination method of BDS-3 system, etc. The spacetime datum, signal-in-space quality, accuracy of satellite broadcast ephemeris, the accuracy of the post-processing precise orbit, time synchronization accuracy, satellite clock offset accuracy and the basic PNT service performance of the BDS-3 baseline system have be calculated and analyzed [3][4][5][7][8][9][10]. Because BDS-3 satellites are equipped with inter-satellite links (ISL), more research achievements have been made in the fields of ISL supported determination of satellite orbit and clock offset [3][4][5][11][12][13].…”
