BDSBAS is an important part of BDS. It improves the positioning accuracy and service level of GNSS by broadcasting the ephemeris corrections and other augmentation information through geostationary earth orbit satellites in real time. This paper studies the enhanced positioning algorithm of BDSBAS according to the relevant standard protocol files, designs and realizes the receiving of the signal of BDSBAS on the BDSBAS monitor receiver, and completes the real-time enhanced positioning solution of single frequency and dual frequency. The results show that BDSBAS-B1C signal can effectively improve the single-frequency positioning accuracy of GPS L1C/A. Compared with the standard service single-frequency positioning, the positioning accuracy of horizontal direction and elevation direction is increased by 45.18% and 70.61%, and the positioning accuracy is about 1m after the enhancement. BDSBAS-B2a signal can improve the positioning accuracy of BDS B1C-B2a dual-frequency ionosphere-free combination to a certain extent. Compared with the standard service dual-frequency positioning, the positioning accuracy of horizontal direction and elevation direction is improved by 6.15% and 5.83%, and the positioning accuracy reaches decimeter level after the enhancement.
