The Gravity field and steady-state Ocean Circulation Explorer (GOCE) is the first Earth Explorer core mission of the European Space Agency (ESA). It was launched on 17 March 2009 from Plesetsk, Russia.
As part of the activities carried out by the Navigation Support Office at ESOC, precise ephemerides of the GOCE satellite have been reconstructed for the entire reentry phase based on the available GPS observations of the onboard LAGRANGE receiver. During the last days of the mission, after GOCE ran out of fuel, it slowly decayed before finally reentering the atmosphere on 11 November 2013.
The reentry orbits, in SP3 format, covering the period from the 21 October to the 10 November 2013 can be downloaded from our page at the following:
Each orbit file covers a 24-hours daily arc, except the last one (DoY 314), where GNSS data were available for GOCE until the end of the latest pass (around 18:00).
These results were presented at the 5th International GOCE user workshop, November 25-28, Paris, France and the proceeding paper can be downloaded here .
