| 摘 要： | 动态GPS（RTK）在城市控制测量中,因受诸多条件的限制,大多情况下需要与常规测量相结合才能完成一个完整的工程项目,因此就需要对RTK的精度进行客观的评定。用误差传播定律理论结合实例对两种作业模式进行分析,证实RTK测量点位精度高且精度分布均匀,但RTK测量达不到常规导线点相邻点间的相对精度。按现行规范对导线点的精度要求,使用RTK作业时,布设点位的要求应改变,边长应适当加长。

| Abstract: | In city control survey,Dynamic GPS(RTK) needs to be combined with conventional measurements to complete a whole project in most cases as a result of some restriction.Therefore the accuracy of RTK needs to be objectively assessed.After an analysis of two modes of operation with the law of error propagation theory,RTK is confirmed to be with accurate and evenly distributed measurement points,but with less relative accuracy of adjacent wire points than conventional RTK measurement.In accordance with the existi... |
