The GFZ/D-PAF orbit prediction system with emphasis on the low flyer GFZ-1

摘要

Since July 1991, the GFZ/D-PAF orbit prediction system provides rgular orbit predictions for several satellites to the SLR community. During this five years practice many improvements towards automatisation and quality have been achieved in the system. The orbit prediction accuracy is increasing continuously. A short report about the orbit prediction quality for RES-2 as well as for the completed ERS-1 and Meteor-3 tracking campaigns is given.
