definition: [Source: ESA's Gravity Mission GOCE Brochure, http://esamultimedia.esa.int/docs/BR209web.pdf ] The Satellite-to-Satellite Tracking Instrument (SSTI) consists of an advanced dual-frequency, 12-channel GPS receiver and an L-band antenna. The SSTI receiver is capable of simultaneously acquiring signals broadcast from up to 12 spacecraft in the GPS constellation. The SSTI instrument delivers, at 1Hz, so-called pseudo-range and carrier-phase measurements on both GPS frequencies, as well as a real-time orbit navigation solution.
