The European Geostationary Navigation Overlay Service (EGNOS) is a satellite-based augmentation system (SBAS) developed by the European Space Agency and EUROCONTROL on behalf of the European Commission. Currently, it supplements GPS by reporting on the reliability and accuracy of their positioning data and sending out corrections.

GNSS augmentation is a method of improving a navigation system's attributes, such as accuracy, reliability, and availability, through the integration of external information into the calculation process, for example, the Wide Area Augmentation System, the European Geostationary Navigation Overlay Service, the Multi-functional Satellite ...
GAGAN is now in operational phase and is compatible with other SBAS systems such as the Wide Area Augmentation System (WAAS), the European Geostationary Navigation Overlay Service (EGNOS) and the MTSAT Satellite Augmentation System (MSAS) and will provide seamless air navigation service across regional boundaries.

A satellite in a geostationary orbit appears stationary, always at the same point in the sky, to ground observers. Popularly or loosely, the term "geosynchronous" may be used to mean geostationary. [1] Specifically, geosynchronous Earth orbit (GEO) may be a synonym for geosynchronous equatorial orbit, [2] or geostationary Earth orbit. [3]
The Lockheed Martin A2100 geosynchronous spacecraft series is designed for a variety of telecommunications needs including K a band broadband and broadcast services, fixed satellite services in C-band and K u band payload configurations, high-power direct broadcast services using the K u band frequency spectrum, and mobile satellite services using UHF, L-band and S-band payloads.
The M970 Semi-Trailer Refueler is a 5,000-U.S.-gallon (19,000 L; 4,200 imp gal) fuel dispensing tanker designed for under/overwing refueling of aircraft. It is equipped with a filter/separator, recirculation system and two refueling systems, one for underwing and one for overwing servicing.
