Primary goal of this project is to derive large scale mass transports in the Earth system from positions of Low Earth Orbiters equipped with a GNSS receiver. At the moment this is hardly possible, because state of the art methods are degraded by systematic influences and are not able to provide sufficient accuracy. To reach this goal a new approach for kinematic orbit estimation will be investigated and implemented. Kinematic orbits will be computed for several satellite missions, as for example CHAMP, GRACE and GOCE.
This project is funded within the Austrian Space Applications Program (ASAP) Phase IX by the Austrian Research Promotion Agency (FFG).
