摘要
系统地清理了山东测区1991年以来采用LCR-G型重力仪观测的21期历史资料,并对每期采用改建后的LGADJ数据处理软件进行单期平差、多期整体平差计算,查找历史资料出现的问题,最后对历史资料的异常点位识别和重力变化计算进行统计分析,为最后进行华北地区统一平差计算及统一入库提供有力保障。
21 years historical measurement data by LCR-G gravimeter since 1991 in Shandong area are straightened systematically. Using the rebuilt LGADJ data processing software, single-year and multi-year average adjustment are performed to figure out the problems existing in the historical data. The historical data anomaly recognition and gravity variation are calculated by statistical analysis. This work provides a strong support for final unified adjustment and storage of the data in North China area.
