基于TEQC与QCVIEW32的单基站CORS数据质量分析

The Data Quality Analysis to Single Base Station Based on TEQC and QCVIEW32

TEQC是GPS观测数据在预处理阶段常用的工具,具有格式转换、数据编辑、质量检核3个方面的基本功能,可针对数据的观测质量进行分析。为验证单基站CORS观测数据质量,利用TEQC质量检核功能进行数据分析,采用QCVIEW3进行可视化展示。实验结果表明该方法可有效地对观测数据进行可视化分析,从而掌握CORS站的数据质量情况。

TEQC is a commonly used tool for GPS observation data in the preprocessing stage.It has three basic functions to analyze the observation quality of the data by format conversion,data editing,and quality inspection.In order to verify the quality of single base station CORS observation data,the TEQC quality inspection function is used for data analysis,and QCVIEW3 is used for visual display.The experimental results show that the method can effectively visualize the observation data,so as to grasp the data quality of the CORS station.
