摘　　要：数据观测质量和基线解算指标等方面对比分析了两种不同型号GNSS接收机(国产和进口)采集得到的GPS观测数据,结果表明两种接收机数据采集质量具有很高的一致性,中长基线相对定位精度均可以达到10-9水平,两者差异可以忽略不计。The paper compares and analyses the GPS observation data collected by two different types of GNSS receivers(domestic and imported)from the aspects of data observation quality and baseline calculation index.The results show that the data acquisition quality of the two receivers is highly consistent,and the relative positioning accuracy of medium and long baselines can reach 10-9 levels,and the difference between them can be neglected.
