Abstract

With a Ferranti FILS MKII an inertial observation campaign was carried out on a testnet in Bavaria including 40 stations and two long traverses in the Alpine foreland. Data have been preprocessed by own software utilizing the two step method with smoothing splines for the error velocity function. The network data then were fitted to 5 control stations. A comparison with other control stations exhibit mean square deviations of 30 cm in latitude, 40 cm in longitude and 25 cm in height. Through improved operation layout and software these values could be reduced to about 50%. For the most rugged part of the alpine traverses gravity values were derived from the inertial data with an accuracy of about 6 mGal.
