摘要
根据现行规范结合实际生产实践,运用平面四参数坐标转换法对GNSS控制网起算点进行兼容性检验的基础上,以实例分析了GNSS控制网起算点的兼容性及其分布对平差结果的影响,对GNSS控制网起算点的选择具有一定的借鉴作用。
According to existing norms and combined with the actual production practices, this paper firstly tests the compatibility of GNSS control network starting points by using of plane coordinates of four parameters for conversion, and then analyzes the influence of adjustment resuhs caused by the GNSS control network starting points＇ compatibility and distribution with a case. It provides a certain reference on the selection of GNSS control network starting point.
