| Abstract: | With the launching of the BeiDou-3 Navigation Satellite System (BDS-3), the BeiDou satellite ground-based augmentation system of Hubei province needs to be upgraded. It means the software and hardware of the entire network to achieve functional support for the BDS-3 satellite. This article introduces the content of this upgrade in detail: the upgrade of board hardware and firmware package of 72 true CORS R1 receivers, and providing support for the BDS-3 satellites; the software upgrade of the true NET platform. After the upgrade, the receiver regression test and system accuracy tests were carried out: the data quality analysis and double-difference quality analysis of the newly added frequency signal were carried out, and the number of satellites, altitude angle were analyzed for the original RINEX file; the performance of the receivers after upgrade are also evaluated. It shows that all indicators meet the requirements; the network real-time kinematic (RTK) positioning accuracy is better than 3 cm in horizontal and better than 5 cm in vertical; Differentinal Global Navigation Satellite System (DGNSS) positioning accuracy is better than 1m in horizontal and 2 m in vertical. |
