Ariane 5 is a retired European heavy-lift space launch vehicle developed and operated by Arianespace for the European Space Agency (ESA). It was launched from the Centre Spatial Guyanais (CSG) in French Guiana. It was used to deliver payloads into geostationary transfer orbit (GTO), low Earth orbit (LEO) or further into space. The launch vehicle had a streak of 82 consecutive successful launches between 9 April 2003 and 12 December 2017. Since 2014, Ariane 6, a direct successor system, is in development.
A geostationary transfer orbit (GTO) or geosynchronous transfer orbit is a type of geocentric orbit. Satellites that are destined for geosynchronous (GSO) or geostationary orbit (GEO) are (almost) always put into a GTO as an intermediate step for reaching their final orbit.
Skynet is a family of military communications satellites, now operated by Airbus Defence and Space on behalf of the United Kingdom's Ministry of Defence (MoD). They provide strategic and tactical communication services to the branches of the British Armed Forces, the British intelligence agencies, some UK government departments and agencies, and to allied governments. Since 2015 when Skynet coverage was extended eastward, and in conjunction with an Anik G1 satellite module over America, Skynet offers near global coverage.

Paksat-1,, was a geosynchronous and communications satellite built and owned by the Boeing Company, leased to the Space & Upper Atmosphere Research Commission (SUPARCO) and renamed Paksat-1. It was successfully put on orbit on 1 February 1996 as Palapa-C1 for Indonesia as its original customer. But, after the technical problems, the satellite was leased to SUPARCO at an orbital location of 38° East longitude in December 2002. Paksat-1 offers the C-band and Ku-band coverage in over 75 countries across Europe, Africa, Middle East, South and Central Asia. Its customers included government organizations, television broadcasters, telecommunications companies, data and broadband internet service providers.
HYLAS is a British satellite in geostationary orbit. HYLAS, which is an acronym for Highly Adaptable Satellite, is a communications satellite and was launched by the European Ariane 5 launch vehicle from the Guyana Space Centre at Kourou in French Guiana. It is located at the orbital location of 33.5 degrees west and will provide new and innovative services including High Definition Television (HDTV) and interactive satellite delivered broadband services. The satellite will help address the issue of poor broadband coverage in many parts of Europe which have less developed ground infrastructure.
Artemis was a geostationary earth orbit satellite (GEOS) for telecommunications, built by Alenia Spazio for ESA. The Artemis satellite operated at the 21.5E orbital position until 2016, when it was moved to 123E to cover the L-Band spectrum rights for Indonesia's Ministry of Defense.
Astra 1M is a geostationary communications satellite which is operated by SES. It is positioned in geostationary orbit at a longitude of 19.2° East, from where it is used to provide direct to home (DTH) broadcasting to Europe, Africa, and the Middle East.
The European Data Relay System (EDRS) system is a European constellation of GEO satellites that relay information and data between satellites, spacecraft, UAVs, and ground stations. The first components were launched in 2016 and 2019.
The space segment of an artificial satellite system is one of its three operational components. It comprises the satellite or satellite constellation and the uplink and downlink satellite links.
