Although the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) gradiometer is highly accurate, it is not possible to map the complete gravity field at all spatial scales with the same quality. To overcome this limitation the position of the GOCE satellite is tracked by GPS relative to GPS satellites at an altitude of 20 000 km – this procedure is known as satellite-to-satellite tracking. The gradiometer is used to measure small scales of the gravity field whilst GPS is used to obtain large-scale data.

GOCE realtime graphic showing orientation in Fine Pointing Mode as of 18:01 CET, 19 March 2009.

This screenshot was taken from the Flight Dynamics system and shows GOCE oriented in orbit after achieving Fine Pointing Mode. The two green arrows pointing to the left are aligned, indicating that the spacecraft is properly oriented along the direction of flight, thus minimising drag.
