Geodetic Information Systems and Web Applications
Web pages of the International Earth Rotation Service
This service provides information on astronomical and global terrestrial reference systems and the data on the rotational behavior of the Earth.
GNSS Data Center of the BKG
The Data Center collects the data of almost 200 globally distributed GNSS permanent stations for various international, European and national projects.
Information system for the BKG stations of the Integrated Geodetic Reference Network of Germany - GREF (only in German)
Information system of the project for establishing the European Combined Geodetic Network - ECGN
Information system for the European Vertical Reference System - EVRS
Information system for European Coordinate Reference Systems - CRS-EU
The system contains the description for national European and pan-European coordinate reference systems for position and height and transformation parameters to pan-European Coordinate Reference Systems and online transformation for single points.
ATMACS - Atmospheric Attraction Computation Service
ATMACS is a joint service of BKG and DWD (Deutscher Wetter Dienst - German Weather Service) and provides time series for correction of atmospheric mass attraction in Gravimetry.
Absolute Gravity Database AGrav of BKG and BGI
The international database AGrav (Absolute Gravity Database) is a joint service of BKG and the BGI Bureau Gravimetrique International - International Gravimetric Bureau) to store and provide the results of absolute gravity measurements worldwide.
