## Analysis method of iGPS measurement uncertainty spatial distribution

• 摘要: 针对iGPS实际测量现场的快速评估与布局优化问题,研究了iGPS测量不确定度空间分布规律.给出了iGPS测量模型,据此建立了iGPS测量不确定度通用两站分析模型,进一步提出了基于两站模型变换的测量不确定度空间分布分析方法,并根据发射器覆盖范围进行了修正.该方法适用于发射器为任意数目与空间布局的iGPS测量环境,可用于计算iGPS测量环境中任一空间点的测量不确定度.构建了iGPS两站与四站实际测量环境,并进行了数值仿真计算与实际测量偏差对比.结果表明,两者数据吻合良好,该iGPS测量不确定度空间分布分析方法能有效描述iGPS测量不确定度空间分布规律.
