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 ...

Since 20 February 2018, Meteosat-11 provides the main full Earth imagery service over Europe and Africa (with images every 15-minutes). [ 9 ] MSG-4 was successfully launched into space on 15 July 2015 at 18:42 local time on top an Ariane 5 Rocket from the Guiana Space Centre in Kourou, French Guiana.
Geostationary satellites are launched to the east into a prograde orbit that matches the rotation rate of the equator. The smallest inclination that a satellite can be launched into is that of the launch site's latitude, so launching the satellite from close to the equator limits the amount of inclination change needed later.

The first Satcom satellite, Satcom 1, was launched on 13 December 1975. The last satellite, Satcom K2, was placed into orbit on 27 November 1985 and was de-orbited in February 2002. Satcom was first superseded and then replaced by the GE series of satellites. The Satcom system passed to General Electric with its purchase of RCA in 1986.
IRNSS-1 Indian regional navigational satellite system (IRNSS)-1, the first of the seven satellites of the Indian Regional Navigation Satellite System constellation, carries a navigation payload and a C-band ranging transponder. The spacecraft employs an optimised I-1K structure with a power handling capability of around 1660W and a lift off ...
