摘要
《GPS测量规范》规定了GPS测量的等级及各级GPS网相邻点间距离 ,最低级E级网相邻点间距为 1～ 1 0km ,平均边长为 2～5km。根据工程的要求 ,有时控制网相邻点间距仅为几十至几百米 ,文中针对GPS短边网的数据处理和精度进行分析 ,并对GPS网的质量检核进行探讨 ,采用全站仪对网进行检核发现GPS边长误差在 5mm以内。
Based on engineering request, GPS vector length is bounded in the scope of several decameter to several hectometer sometimes. The paper discussed GPS data processing and precision analysis and GPS network quality check on short vector network. GPS short vector precision excel 5 mm by using EDM examining.
