Description: 精密单点定位(Precise Point Positioning, PPP)技术由美国喷气推进实验室( JPL ) 的Zumberge 于1997年提出。20世纪90年代末,由于全球GPS跟踪站的数量急剧上升,全球GPS数据处理工作量不断增加,计算时间呈指数上升。为了解决这个问题,作为国际GPS服务组( IGS)的一个数据分析中心, JPL提出了这一方法,用于非核心GPS站的数据处理。-Precise Point Positioning (Precise Point Positioning, PPP) technology by the U.S. Jet Propulsion Laboratory (JPL) of the Zumberge made in 1997. 90' s at the end of the 20th century, the global GPS tracking sharp rise in the number of stations, the global GPS data processing ever-increasing workload, an exponential increase in computing time. To solve this problem, as the International GPS Service (IGS), a Data Analysis Center, JPL proposed this approach for non-core data-processing of GPS stations.
