河北省GNSS观测数据质量分析

Quality Analysis of GNSS Observation Data in Hebei Province

  • 摘要: 使用TEQC软件评估了河北省地理信息局59个GNSS测站2019年1—9月的观测数据质量,结果表明:大部分测站的数据质量良好,满足地壳运动监测要求;11个测站数据多路径效应影响较大,通过数据处理等方式减小多路径效应MP1、MP2的影响,可用于地壳运动监测;SW01、SZHJ、SZJO、SZLF、SZWX 五个测站数据质量较差,不建议用于地壳运动监测;SZKB测站数据质量在2019年6—9月明显提升,达到地壳运动监测技术要求,建议对其更长时间的数据做质量评价。对观测质量较差的SW01、SZHJ、SZJO、SZKB、SZLF、SZWX 6个测站数据观测质量的影响因素进行分析,并给出了合理建议。

     

    Abstract: In this paper, TEQC software was used to evaluate the observation data quality of 59 GNSS stations in Hebei Province from January to September 2019. The results show that the data quality of most stations is good and meets the requirements of crustal movement monitoring. The influence of multipath effect on the data from 11 stations is large. The influence of multipath effect MP1 and MP2 can be reduced by means of data post-processing, etc., which can be used for crustal movement monitoring. The data quality of SW01, SZHJ, SZJO, SZLF and SZWX stations is poor, so it is not recommended to be used for crustal movement monitoring. The data quality of SZKB station has been significantly improved from June to September 2019, meeting the technical requirements of crustal movement monitoring. Therefore, it is suggested to evaluate the quality of longer time data. The factors affecting the data observation quality of SW01, SZHJ, SZJO, SZKB, SZLF and SZWX stations with poor observation quality were analyzed preliminarily and reasonable suggestions were given.
