| 摘 要： | 精密单点定位(PPP)是当前GPS界研究的热点之一。为讨论其精度及收敛性,应用TriP软件处理分析5 min、30 min、2 h、24 h不同时段长度的单站GPS观测值。结果表明,随着观测时间的增加,定位精度不断提高,30 min内即可稳定在厘米级,最终实现毫米级精密定位。与此同时定位结果不断收敛,且收敛速度由快变慢,前15 min收敛较快,此后随观测时间的增加收敛速度逐步变慢且逐渐趋于缓和。

| Abstract: | Research on the precise point positioning(PPP) is one of the hot topics in the GPS field.To discuss the precise and convergence,different single GPS observations,which are selected by 5 minutes interval,30 minutes interval,2 hours interval and 24 hours interval,are calculated by the software named TriP.The results show that: the precise of PPP improves gradually and the result will be stable at cm-level in thirty minutes and it will achieve mm-level as time increased.At the same time,the convergence rat... |
