摘要UIVAVCO开发的TEQC是用来进行GPS数据预处理的软件，是目前国际上公认的较为优秀的数据质量检查软件。在对GPS中的观测误差进行评估时，它是利用伪距和载波相位观测值的线性组合来实现的。在GPS数据进行格式转换、编辑、质量检查中，TEQC软件是一款非常优秀的常用工具。76486
本文主要利用TEQC软件进行数据的处理，研究了三个部分。首先，第一部分是对CORS站CGXY单站的数据质量，数据完整性、多路径效应以及周跳进行分析。第二部分，重点是对bill、fzhs、dmfb、crbt、chum这五个站三天的数据质量情况进行分析，主要分析了五个站的周跳以及信噪比等。结果显示：2016年的001、006、020，五个站中的 crbt、dmfb、fzhs、bjfs数据质量很好，完整性100%。bill、crbt两个站的数据质量虽然不是很完美，但是也满足质量检核的标准，数据完整性为98%。第三部分，采用的是abgs这个站，取30天的观测数据，对其进行质量研究与分析。结果显示：MP1的变化波动值不是很大，MP2的波动值在二十天往后有点波动，受到环境的影响，CRS波动较大 ，并且分析了信噪比随卫星高度角的变化，信噪比刚开始随着卫星高度角的增加而增加，后来逐渐趋于平缓 。通过三个实例的分析，最终都将结果进行可视化。

Abstract Quality inspection software TEQC is developed and used in the GPS data preprocessing software by the UIVAVCO organization。 It is an internationally recognized software for data quality inspection。 It uses the linear combination of the pseudo range and carrier phase observation value to evaluate the observation error of GPS。 In the rapid assessment of the quality of GPS data is very good, is the data format conversion, editing, quality inspection tools。
In this paper, the main use of TEQC software for data processing, the main research of the three parts。 First of all, the first part of this paper is to analyze the data quality, data integrity, multi path effect and cycle slip of CORS station CGXY station。 The second part of this paper, focusing on the bill, fzhs, dmfb, CRBT, chum, BJFS three days of data quality analysis of the six stations, the main analysis of the six stations of the cycle jump and the signal to noise ratio, etc。。 The results showed that: on the first day of 2016, sixth days, Twentieth days, six stations in the CRBT, dmfb, fzhs, BJFS data quality is very good, the integrity of 100%。 Bill, CRBT two stations of the data quality is not very perfect, but also to meet the quality of the core of the standard, the data integrity of 98%。 The third part of this paper, using the ABGs station, take 30 days of observation data, the quality of its research and analysis。 The results showed that MP1 changes in the values of the fluctuations in the value of is not very big, fluctuations in the MP2 values in twenty days later have fluctuations, by the environment influence, CRS volatile, and the analysis of signal to noise ratio and satellite elevation angle changes, signal to noise than just getting started with the increase of satellite elevation angle and increase, and later gradually flatten。 Through the analysis of three examples, the results will be visualized。
