Study on Fast Positioning Algorithm for BeiDou Post-Mission Network RTK

Abstract

Abstract Aiming at the GNSS data resolving process and the network RTK positioning algorithm for the multisystem of GPS/BDS/GLONASS, C# and C++ programming were used to develop the resolving software of fast positioning for BeiDou post-mission Network RTK. The software supported self-defined resolving time and could resolve three dimensional user coordinates in a short time. The software was tested with the measured data from the BeiDou high precision reference station network in Guangxi and compared with the TBC+COSA_GPS processing software. And the results show that the proposed software could provide rapid positioning results for users with a centimeter-level precision.
