从位置精度方面验证了实时单频精确点定位的性能。这种精确的点定位技术依赖于预测的卫星轨道，预测的全球电离层图，特别是实时卫星时钟估计。仅使用来自用户接收器的L1频率（C1和L1）的测量结果，提供了近3个月的数据。北、东方向定位误差的经验标准差约为0.15 m，上方向定位误差的经验标准差约为0.30 m。95%的误差在水平方向约为0.30 m，垂直方向约为0.65 m。此外，还介绍了分布在世界各地的六个接收机的单频结果。本研究揭示了当前单频定位的终极实时性能。为了更好地理解这些结果，我们使用一个价格适中的接收器和一个简单的贴片天线进行了一个案例研究。
The performance ofreal-timesingle-frequency precise point positioning is demonstrated in terms of position accuracy. This precise point positioning technique relies on predicted satellite orbits, predicted global ionospheric maps, and in particular on real-time satellite clock estimates. Results are presented using solely measurements from a user receiver on the L1-frequency (C1 and L1), for almost 3 months of data. The empirical standard deviations of the position errors in North and East directions are about 0.15 m, and in Up direction about 0.30 m. The 95% errors are about 0.30 m in the horizontal directions, and 0.65 m in the vertical. In addition, single-frequency results of six receivers located around the world are presented. This research reveals the current ultimate real-time single-frequency positioning performance. To put these results into perspective, a case study is performed, using a moderately priced receiver with a simple patch antenna.
