High Precision Tidal Gravity.

Abstract

The progress made on the conversion to electrostatic feedback of the LaCoste tidal gravimeters ET10, ET13 and ET15 is reported. Tests on the absolute calibration of the gravimeters and the calibration/non linearity of the feedback system are described. A system has been designed and constructed for the continuous and reliable recording of high resolution tidal gravity data over a wide range. Some tests on this system are described. (Author)
