BDS-3/BDS-2及BDS-3+BDS-2高精度控制测量定位性能分析
Positioning Performance Analysis for High-Precision Control Surveying of BDS-3/BDS-2 and BDS-3+BDS-2
摘要
Abstract
By establishing a BDS transmission reference control surveying model,the paper compares and analyzes the high-precision control surveying positioning performance differences between BDS-3/BDS-2 and BDS-3+BDS-2.Nine first-order control points of a project in Beijing and three IGS track-ing stations in China and its surrounding areas were selected to establish a high-precision control sur-veying positioning network that supports both GPS and BDS-3/BDS-2 signals.Continuous observation data from three time periods(days 153-155 of 2023)were selected,and four schemes were designed for data processing.The positioning performance was compared and analyzed from two aspects:the transmission results of the initial reference and the adjustment results of control surveying.The re-sults show that compared with GPS,BDS-3 and BDS-3+BDS-2 have only millimeter-level differences in N,E,U,horizontal,and point directions,while BDS-2 has differences ranging from millimeters to centimeters in the U and point directions,and only millimeter-level differences in the N,E,and hori-zontal directions.The measurement accuracy of BDS-3 is basically equivalent to that of BDS-3+BDS-2,while BDS-2 has lower accuracy than the other two,especially in the U direction.关键词
