摘要(Abstract)：

针对非差实时精密单点定位应用中,如何判定定位精度是否达到用户应用需求的问题,该文提出了一种基于位置、对流层湿分量、模糊度参数时间序列,综合分析非差精密单点定位是否收敛的新方法。该方法给出了收敛精度判定参数P值的定义与经验阈值,通过计算获取P值,判定定位结果是否收敛。通过实测数据分析对该文方法进行实验验证,结果表明:P值首次达到0.5以上时,三维定位收敛精度优于15 cm的判定成功率达到55%,优于25 cm的判定成功率达到75%以上;P值首次达到0.9以上时,三维定位收敛精度优于15 cm的判定成功率达到75%以上,优于25 cm的判定成功率达到92%。

关键词(KeyWords)： 非差精密单点定位;收敛判定方法;判定指标;成功率
