The European Space Agency (ESA) GOCE Core Explorer Mission will carry a 12-channel, dual-frequency GPS receiver for high-accuracy precise orbit determination. Precise GOCE orbit solutions will be used to accurately geolocate the observations taken by the primary science instrument, the gradiometer, that aims at collecting medium to short wavelength gravity information. In addition, the orbit solutions will provide complementary information for the long-wavelength gravity field part. Precise orbit determination is an integral part of the GOCE High-Level Processing Facility (HPF) that aims at producing the best gravity field model products possible. A rapid (RSO) and precise science orbit (PSO) determination chain will be implemented at respectively DEOS and AIUB with typical latencies of 1 day and 1 week. The RSO chain will support the operations of the GOCE satellite allowing quick checks of the scientific data streams and quick-look gravity field solutions. The PSO chain will provide the most accurate GOCE orbit solutions possible for use in the final gravity field determinations. This paper provides a brief overview of the HPF orbit determination architecture and products.
