卫星导航脱敏观测数据文件

卫星导航脱敏观测数据文件产品，可以为卫星导航定位服务商、科研机构提供卫星导航脱敏观测数据。文件长期存储。可用于事后数据处理，维持基准站网坐标框架，分析基准站数据质量变化趋势，导航卫星精密星历、钟差等产品的事后生产，坐标变化时间序列分析，地震的震前、震中、震后评估，分析对流层变化、电离层变化、降水量变化、地壳运动等。Satellite navigation de-identified observation data file products provide de-identified satellite navigation observation data to satellite navigation positioning service providers and scientific research institutions. The files are stored for long-term preservation. They can be applied to post-event data processing, maintaining the coordinate framework of reference station networks, analyzing the variation trends of reference station data quality, post-processing production of products such as precise ephemerides and clock offsets of navigation satellites, time series analysis of coordinate changes, pre-earthquake, epicentral and post-earthquake assessments of earthquakes, as well as analyses of tropospheric changes, ionospheric changes, precipitation variations and crustal movements.
