高崖口重力短基线的校准与分析
|
摘要
介绍北京高崖口国家重力仪短基线标定场的测量情况,分析高精度相对重力联测和使用A10绝对重力仪进行4期校准得到的结果精度。结果表明,高崖口短基线场基2点与基5点间的重力段差长期变化在20μGal以内,点位稳定可靠。
We introduce the measurement of Beijing Gaoyakou short gravity calibration baseline and analyze its calibration by relative gravity measurements and four times A10 absolute gravity measurements. The results show that the gravity change between basic point 5 and 2 is less than 20 μGal, and that Gaoyakou short gravity calibration baseline is steady.
