摘　　要：研究了北斗动态单历元的周跳探测及模糊度解算方法,并编制相关基线解算软件。在我国中纬度某城市采集实测数据,测试分析该算法解算短基线的内符合精度及外符合精度。结果表明,北斗短基线南北方向精度优于7mm,东西方向精度优于5mm,高程方向精度优于15mm,外符合位置精度优于5mm。In this paper, we study a method of cycle-slip detection and ambiguity resolution for Beidou single epoch dynamic baseline solutions, and compile relevant software. We get the measured data from one middle latitude city and then analyze the inner precision and outer precision of the algorithm, calculating short baseline. Results show that north-south direction accuracy is better than 7 ram, eastwest direction accuracy better than 5 mm, elevation direction accuracy better than 15 mm; the outer location precision is better than 5 mm.
