The aim of the presentation is to provide an overview of the GPS receiver on board GOCE, GOCE SSTI, manufactured by AAS-I, Milan plant. In particular the design of the instrument is addressed in the first part of the presentation and some performance aspects (real-time navigation, measurement accuracy, robustness against ionospheric scintillation) are described later on.

A past experience of a precursor of SSTI (ENEIDE) that was flown in 2005 on the International Space Station is also briefly presented as a flight experience.
