Telemetry data from the Electrostatic Gravity Gradiometer (EGG) and from the Satellite-to-Satellite Tracking Instrument (SSTI) are automatically processed at ESA up to level 1b.

All intermediate processing results are stored within the final products.

The main product from EGG is called EGG_NOM_1b and it contains several data sets, corresponding to differents degrees of processing (from the accelerometers control voltages to the gravity gradients).

The main product from SSTI is called SST_NOM_1b and, like the EGG_NOM_1b, it is composed by several data sets that correspond to differents degrees of processing (from raw pseudoranges and carrier phases, including inter-channel and interf-frequency biases, and up to the computation of GOCE orbit).

The main processing steps will be presented in the paper, together with a description of products format and content.
