MONITORING OF VARIATIONS OF THE GRAVITATIONAL FIELD IN CONTINENT-OCEAN BORDER ZONE BY THE ABSOLUTE LASER BALLISTIC GRAVIMETER
The description of the modernized interferometer of the absolute laser ballistic gravimeter GABL-E developed in Institute of Automation and Electrometry SB RAS is presented. The optical standard with wave length of radiation λ=532 nm consisting of Nd:YAG-laser and system of frequency stabilization is applied as a light source in the interferometer. The instrumental mean square error of absolute gravity value measurement is not more than ±5∙10-8 m/s2 (5 µGal). The results of monitoring of periodic and irregular gravity variations in continent-ocean border zone are presented.
