新型 Scintrex 重力仪 CG5 于 2002 年投放市场。CG5/352 是 CG3M/352 的升级版，在各个领域进行了测试。 CG5仪表具有新的原始数据采集模式。如果启用该模式，未处理的 6 Hz 数据（重力、x 倾斜、y 倾斜和温度）将存储在内存中。我研究了原始数据记录在提高重力监测效率方面的潜力。可以通过以各自的重复间隔进行剖面或面积覆盖的重力测量来监测数月和数年演变的长期变化。如果预计会出现短期变化，则需要高填充率和/或连续重力记录。在这两种情况下，对原始数据进行后处理对于检测信号都是有效的。 CG5测量仪连续测量和重复测量相结合，可以覆盖时间和空间域上相当大的范围。
A new Scintrex gravimeter, CG5, was released onto the market in 2002. The CG5/352, which was upgraded from the CG3M/352, was tested at various fields. CG5 meter has a new raw data acquisition mode. If the mode is enabled, unprocessed 6 Hz data (gravity, tilt-x, tilt-y, and temperature) are stored in memory. I examined the potentialities of the raw data recordings to improve efficiency of gravity monitoring. Long-term changes which evolve over months and years can be monitored by gravity measurements with profile or areal coverage at respective repetition intervals. If short-term changes are expected, high repletion rates and/or continuous gravity recordings will be required. Postprocessing the raw data is effective to detect signals both in the cases. A combination of the continuous measurements and reiteration surveys with CG5 meter can cover a considerable part of the ranges both in time and space domains.
