Definition
- The GGP Project (http://www.eas.slu.edu/GGP/ggphome.html) is a long term initiative in order to establish a world wide network of super conducting gravimeter (SG) stations by the voluntary consolidation of unique observatories using such devices. The first phase of the project ran from July 1997 to July 2003. The second phase continuing this project will last until 2007. The high accuracy gravity data are used for study of global motions of the entire Earth as well as for the estimation of local gravity effects caused by atmospheric pressure and groundwater. By the start of high accurate satellite gravity missions CHAMP and GNSS, the SG data got a new impact for the validation and calibration of these missions. (en)
