Data products

The two main data products from the GOCE mission are Level-1b and Level-2.

Level-1b data products are the time series of converted, calibrated and validated measurements taken by GOCE. They consist mainly of the gravity gradients in the local satellite reference system and the orbit data (Satellite-to-Satellite Tracking observations, positions and velocity) in an Earth-fixed coordinate system. In addition, satellite data such as the attitude of the spacecraft and other housekeeping data complete the Level-1b data.

These data were subsequently processed to Level-2. They consist of a spectral representation of the gravity potential on a sphere, gridded values of geoid heights and gravity anomalies, including error information and calibrated gravity-gradients in different reference frames.

All products are available free of charge to scientific and non-commercial users.
