为了克服传统陆地重力梯度测量方法的不足,提出了利用两台或多台具有电子读数的相对重力仪测量重力梯度的同步观测方法和相应的数据处理模型,该方法无需进行固体潮改正和零漂改正而直接求解重力差,垂直重力梯度实验结果验证了该方法的有效性。
In order to overcome the shortcomings of traditional observation method for land gravity gradient, simultaneous observation method using two or more gravimeters with elec- tronic output is presented, and simultaneous observation data processing models are also giv- en in the paper. The method can provide the solution of gravity difference directly without tidal correction and drift correction. The test results of vertical gravity gradient show that the method is very effective.
