精密单点定位技术发展及应用

综述了精密单点定位(precise point positioning,PPP)技术的发展及其应用现状。主要从PPP模糊度解、实时PPP和多系统组合PPP等3个方面进行了总结。根据PPP技术的优点,阐述了该技术在测绘、监测、气象和水汽遥感等方面的实际应用。针对最新发展起来的多频多模块多系统联合定位,展望了PPP技术未来的发展趋势,最后指出随着PPP技术的成熟及模型的精细化和改进,PPP快速初始化的问题有望得到突破,PPP技术的应用会更广泛。

Development and application of Precise single Point Positioning technology

The development of Precise Point Positioning (PPP) technology and its application status are comprehensively described. It is mainly summarized from three aspects: PPP ambiguity solution, real-time PPP and multi-system combination PPP. According to the advantages of PPP technology, the practical application of this technology in surveying, monitoring, meteorology and water vapor remote sensing is expounded. Aiming at the newly developed multi-frequency, multi-module and multi-system joint positioning, the future development trend of PPP technology is forecasted. Finally, with the maturity of PPP technology and the refinement and improvement of the model, the problem of rapid initialization of PPP is expected to be breakthrough. PPP technology The application will be more extensive.
