高精度定位和定轨服务依赖参考站的准确坐标,在实时传输计算过程中无法实现对参考站坐标的保密,为此本文提出了基于空间误差相关性的参考站位置偏置方法,在进行参考站位置偏置时,认为偏置参考站的大气误差与原参考站一致,同时结合偏置参考站到卫星的几何距离,生成原参考站附近的偏置参考站,偏置参考站观测值与原参考站观测值误差特性一致,可以代替实际参考站实现高精度定位定轨服务。为评估偏置参考站对高精度定位和精密定轨的影响,本文对偏置参考站的PPP-RTK定位、网络RTK定位、精密轨道确定的性能进行分析。试验结果表明,利用偏置参考站代替实际参考站提供服务时,当原始参考站网各参考站随机偏置900 m时,对NL-UPD估计和PPP-RTK定位结果的影响很小,不影响高精度的PPP-RTK定位。对网络RTK分析表明,参考站位置偏置对模糊度解算和误差改正精度的影响,会随着偏置距离的增大而变大;当位置偏置达到5000 m时,参考站解算的浮点模糊度差异会明显增大,非差误差改正数差异也急速增大,但不影响用户的网络RTK高精度定位,对区域增强定位的影响有限。各参考站随机偏置900 m时,位置偏置对精密定轨的影响也较小,影响最大的BDS-IGSO精密轨道,最大值也仅为8.4 mm,满足高精度精密定轨的要求。
