Being the first mixed-constellation global navigation system, the global BeiDou navigation system (BDS-3) designs new signals, the service performance of which has attracted extensive attention. In the present study, the Signal-in-space range error (SISR
This paper is intended to examine these assumptions and give a thorough characterization of core SIS error behavior based on the statistics of recent data. The radial, alongtrack, and crosstrack ephemeris errors and clock errors are computed by comparing the broadcast ephemerides/clocks with the ...
In terms of the broadcast clock error, the averages of the standard deviations (SD) are 0.4 m and 0.2 m for BDS-2 and BDS-3, respectively. However, significant satellite-dependent nonzero clock bias is also observed for the BDS-3 satellites, and this bias could be partly reduced using ...
Assessment of long-term BDS signal-in-space range error and its improvement The accuracies of BeiDou broadcast ephemeris from June 1, 2015 to June 30, 2018 are evaluated by using post-processing precision orbit and clock products. ... C Yu,J Chen,Q Chen,... - 《Dongnan Daxue Xuebao》...

The ARAIM algorithm is affected by several error sources. These errors can be divided into errors that arise in navigation satellites, affect signals during propagation, and emerge from the receiver or its surrounding environment [2]. This paper focus on analyzing the errors that arise in ...
