摘要
通过整合基线数据、尺度因子以解决数据兼容性后,采用统一的起算基准与平差软件,对某测区不同时期布设的高精度GNSS控制网进行并网统一平差。最终平差成果精度优良,可满足C级以下的各等级控制网加密及工程建设应用,对于不同期布设GNSS控制网的整合具有一定的参考意义。
A scheme is proposed in this paper to integratively adjust the high accurate GNSS networks seu uo in dif-ferent period. Data compatibility is solved after integrateing baseline data and scale factor. The adjustment scheme is ap-plied to real networks. The adjustment results have good performance and can meet the applications of supplementary control network under C grade and engineering construction.
