The Study on BDS Dynamic Positioning Performance Assessment

We provided the key technologies for BeiDou navigation satellite system (BDS) standard positioning. Using real-time precise point position (RT-PPP) technology to get the precise reference coordinate, the dynamic positioning performance of BDS in service area was evaluated. Our results indicate that the 95% confidence level error is 2.77 and 4.27 m for horizontal and vertical components with B1I signal, 3.24 and 4.95 m for B2I signal, and 4.11 and 6.84 m for B1I and B2I ionosphere-free combination.
