基于TEQC软件的GPS数据质量检查分析

On the Data Quality Check of GPS Based on Software TEQC

主要论述利用TEQC软件对GPS数据进行数据质量检查分析的方法.在分析影响GPS观测数据质量的误差来源的基础上,通过TEQC数据质量检测软件,研究了可以反映出GPS数据的电离层延迟、多路径影响、接收机周跳、卫星信号信噪比等信息,并实现了可视化.

This paper mainly discusses the method of data quality check of GPS based on Soft- ware TEQC. Based on the analysis of the data error source of GPS,with the use of TEQC, the I- onospheric Delay, Multipath Effects, Receiver Cycle Slip, Satellite Signal Noise Ratio, which in- fluence GPS data, are studied. Visualization is also realized.
