Abstract

The earth’s gravity field reflects the spatial distribution, movement and change of the earth’s mass. High precision gravity field is one of the main tasks of geodesy. The feasibility research of future China's satellite gravity mission(CSGM) were carried out, the satellite to satellite tracking in the low low mode was selected in the future satellite gravity measure. A precise laser ranging system is a key component to CSGM. In this paper, a laboratory breadboard heterodyne laser interferometer was built, experimental result demonstrated that laser ranging performance in laboratory distances was 1 nm@0.01Hz and below1nm@1Hz in translation measurement, and can meet the demand of CSGM mission.
