摘    要:利用在全球不同海域的船载GNSS进出港数据,以事后动态处理技术(PPK)的坐标计算值为评价基准,分析了Veripos星站差分系统和事后动态精密单点定位技术(PPP)在不同运动状态下的位置服务精度。结果表明,Veripos与PPP在低动态下的平面与高程位置服务精度可优于6.2 cm和14.9 cm,在常规动态下平均精度优于20 cm;PPP与Veripos坐标分量平均互差小于15 cm,标准差小于23 cm,在深远海调查中PPP技术可作为星站差分系统的有效补充和特殊情况下的位置服务替代。

关 键 词:星站差分  PPP  PPK  位置服务  深远海调查

Abstract:Based on GNSS data in different sea areas and postprocessor GPS PPK technology, the accuracy analysis of Star Station Differential (Veripos) and PPP under different motion status are carried out. The results show that, horizontal and elevation service accuracy of Veripos and PPP are better than 6.2 cm and 14.9 cm under low motion status, and average accuracy is better than 20 cm under normal status. The average variances of latitude, longitude and elevation between Veripos and PPP are less than 15 cm and the standard deviation is less than 23 cm. PPP technology can be used as an effective replenishment and special replace to Star Station Differential in deep sea investigation.
Keywords:Star Station Differential  PPP  PPK  location service  deep sea investigation
