摘　　要：基于载波相位观测值的动对动相对定位可以得到双移动测站之间精确的相对位置关系,极大地扩展了动态相对定位的应用领域。GNSS精密动态定位、测速和定姿软件KinPOS针对动对动相对定位的质量控制方法进行优化,并基于三组不同场景下的实测GPS/BDS数据开展了动对动定位性能分析,结果表明:KinPOS软件解算结果稳定可靠,中短基线定位精度优于5 cm;BDS与GPS的动对动定位性能基本相当。The Kinematic-to-kinematic positioning can obtain precise relative position of two mobile stations, which greatly expands the application of kinematic positioning. KinPOS（GNSS Precise Kinematic Positioning and Orientation Software） optimize the quality control methods in Kinematic-to-kinematic positioning. Three sets of data obtained under different scenarios are analyzed based on KinPOS software. The experiment results show that the KinPOS software can get stable and reliable results, in which the positioning accuracies for short and medium baselines are better than 5 cm, and the Kinematic-to-kinematic positioning performances of GPS and BDS are basically the same.
