重庆市国土资源GNSS网络信息系统基准站网数据质量分析关键技术研究

Key Technology and Analysis on Information System Network Quality with GNSS Reference Station Network Data over the State Land and Resources of Chongqing

基准站观测数据的质量是影响连续运行参考站系统(CORS)能否正常、稳定运行的关键因素之一。对于已建成的CORS系统,仍有必要定期对基准站数据质量进行分析监测。本文选取重庆市国土资源GNSS网络信息系统(CQGNIS)基准站网的实际观测数据,分别利用TEQC和GAMIT软件对CQGNIS单基准站和全网数据质量进行分析研究,论证并给出了CQGNIS基准站的当前总体数据质量情况。

The reference quality observation station which is one of the key points to determine the normal and stable operation（CORS） data needs to be monitored and analyzed periodically among the CORS system already built.This document has selected the real observation data from the network of reference stations CQGNIS on information system network of the national land（GNSS） from Chongqing,respectively,using the GAMIT and TeqC software to study and analyze the single reference station CQGNIS and the quality of data across the network to introduce the situation of the overall quality of current data on the reference station CQGNIS.
