| 摘 要： | 利用广东省BDS地基增强系统中的北斗观测数据，采用武汉大学高精度GNSS数据处理软件PANDA，实现了广东省BDS基准站网的高精度坐标解算，重复性精度指标为平面方向0.37 cm，高程方向0.74 cm。基于该结果建立的以BDS基准站网为主的广东省坐标框架，与GPS建立的坐标框架对比发现，平面及高程方向精度分别为0.50 cm、0.94 cm、满足国家二等控制网平面方向5 mm、高程方向10 mm、相对精度不低于1×10-7的精度要求。

| Abstract: | BeiDou data were collected in Guangdong ground-based augmentation system and the data processed using the PANDA software, developed by Wuhan University. The repeatability precision of the BeiDou reference station network can reach up to 0.37 cm in horizontal component, and 0.74 cm in vertical component. Compared with the Guangdong Coordinate Frame established by GPS, the accuracy of the new Guangdong Coordinate Frame, based on the BeiDou Reference Station Network, can be up to 0.50 cm in horizontal component and 0.94 cm in vertical component. This accuracy satisfies the requirements of the national second control network, as the horizontal, vertical, and relative accuracy must be below 5 mm, 10 mm, and 1×10-7 respectively. |
