GFPF - Gravity Field Processing Facility
This includes the development of all required algorithms, the software testing and integration and comprises two main software components:
- The Quick-Look Gravity Field Analysis is applied to compute very fast approximate gravity field solutions in parallel to the mission, in order to derive a fast diagnosis of the GOCE system performance.
- The Core Solver is based on parallel processing on a PC cluster and solves the large normal equation systems (70,000 unknowns) rigorously.
These tasks are performed in conjunction with the ESA-project GOCE High-Level Processing Facility, performed by the European GOCE Gravity Field Consortium (EGG-C). As a by-product of these software developments, Earth’s gravity field solutions from the satellite mission CHAMP could be derived.
Additionally, in the framework of GFPF the benefits of an incorporation of data from complementary satellite missions (CHAMP, GRACE), but also terrestrial and air-borne data, will be investigated.
