Abstract
A new gravity base net (“Schweregrundnetz 1976 der Bundesrepublik Deutschland”, DSGN 76) has been established in the Federal Republic of Germany, to meet the increased requirements of geophysics, geology, metrology and geodesy. The net comprises 21 stations with three excenters each. The gravity values were determined using 4 absolute stations, 11 IGSN71-stations and about 3000 relative gravity meter observations with 4 gravity meters. Instrumental investigations and special treatment of local tidal and atmospheric effects improved the data for the least squares adjustment, which was performed by the method of observation equations following the use of condition equations. The final adjustment showed a point r.m.s. error of about 10μGal[10−8 ms−2]. Detailed results will be published in the ”Veröffentlichungen der Deutschen Geodätischen Kommission”.
