Signals used by SISNeT SISNeT (Signal in Space through the Internet) uses signals from EGNOS, the European Geostationary Navigation Overlay Service. EGNOS is the first step in the European contribution to the Global Navigation Satellite System, and a fundamental stepping-stone towards Galileo, Europe's own Global Navigation Satellite System. EGNOS is an augmentation system to the GPS (Global Positioning Satellite) satellite navigation system, which provides and guarantees navigation signals for aeronautical, maritime and land mobile Trans-European network applications. Satellite broadcasting through geostationary satellites (GEOs) has proved to be an efficient strategy for avionic applications and other modes of transport.
While the EGNOS messages will still be very useful for transport applications, a different transmission link may be needed to take full advantage of the EGNOS potential.
