基于精密单点定位技术的远程GPS验潮
|
摘要
精密单点定位(PPP)技术应用于远程海水验潮,可有效弥补传统验潮方法受距离限制等缺点。本文将单天的IGS观测数据基于Bernese软件进行了单历元PPP解算,探讨了PPP应用于海水验潮的有效性。并采用门限滤波方法提取潮汐信息,通过分析模拟潮位数据及西沙实测数据的内符合精度证明,PPP验潮能够达到厘米级的精度。
The precise point position(PPP)technology is applied to the remote tide observing,which can effectively make up the disadvantage of traditional tidal methods limited by the distance.The paper makes the single epoch PPP calculation for the observation data of single IGS based on Bernese software to discuss the feasibility of PPP applied on the tide observing.PPP tide observing can achieve centimeter level accuracy by the tide information extracted from threshold filtering method and analyzing the analysis of simulated tidal data and the inner precision demonstration of Xisha measured data.
