山东半岛北斗基准站观测数据质量分析与评价

Quality Analysis and Evaluation of BDS Reference Station Observation Data in Shandong Peninsula

摘要:

本文使用数据缺失天数统计软件与TEQC数据预处理软件评估了山东半岛31座北斗基准站2021年全年的观测数据质量，结果表明：大部分北斗基准站的观测数据质量良好，符合后续研究要求；23座北斗基准站全年观测数据质量良好，全年数据均可用于后续研究；HJBH、LJZK、LOKO、SDPL 4座北斗基准站在GPS周2142周和2185周出现仪器故障，后续研究应舍弃这2周数据；RZRS、ZNRS 2座北斗基准站全年数据质量较差，不应用于后续研究；WEIH、SDLA 2座北斗基准站在年积日158d和160d后数据质量明显提升，符合后续研究要求。北斗基准站应加强数据质量动态监测及巡检力度，确保站点数据质量稳定可靠。

Abstract:

In this paper, data missing days statistics software and TEQC data preprocessing software are used to evaluate the observation data quality of 31 BDS reference stations of Shandong Peninsula in 2021. It is showed that the observation data quality of most BDS reference stations is good and meets the requirements of subsequent research. The annual observation data of 23 BDS reference stations are of good quality and can be used for followup research. Instrument failures occurred at four BDS reference stations, HJBH, LJZK, LOKO and SDPL, in GPS Week 2142 and Week 2185, and the data of these two weeks should be discarded in subsequent studies. The annual data quality of RZRS and ZNRS BDS reference stations is poor, so it should not be used in followup research. The data quality of WEIH and SDLA BDS reference stations improved significantly 158 and 160 days after the annual accumulation day, meeting the requirements of subsequent research. BDS reference station should strengthen the dynamic monitoring and inspection of data quality to ensure the stability and reliability of data quality.
