The European Space Operations Centre (ESOC) serves as the main mission control centre for the European Space Agency (ESA) and is located in Darmstadt, Germany. ESOC's primary function is the operation of uncrewed spacecraft on behalf of ESA and the launch and early orbit phases (LEOP) of ESA and third-party missions. The Centre is also responsible for a range of operations-related activities within ESA and in cooperation with ESA's industry and international partners, including ground systems engineering, software development, flight dynamics and navigation, development of mission control tools and techniques and space debris studies.
The British National Space Centre (BNSC) was an agency of the Government of the United Kingdom, organised in 1985, that coordinated civil space activities for the United Kingdom. It was replaced on 1 April 2010 by the UK Space Agency.
Inmarsat is a British satellite telecommunications company, offering global mobile services. It provides telephone and data services to users worldwide, via portable or mobile terminals which communicate with ground stations through fourteen geostationary telecommunications satellites. Inmarsat's network provides communications services to a range of governments, aid agencies, media outlets and businesses with a need to communicate in remote regions or where there is no reliable terrestrial network. The company was listed on the London Stock Exchange until it was acquired by Connect Bidco, a consortium consisting of Apax Partners, Warburg Pincus, the CPP Investment Board and the Ontario Teachers' Pension Plan, in December 2019.

The Romanian Space Agency is a public institution with extra-budgetary funding that coordinates Romania's national space technology research programs and space research-related activities. ROSA was founded in 1991 and is subordinated to the Ministry of Education.
Space Imaging Middle East LLC (SIME) is a regional affiliate of DigitalGlobe, the largest commercial remote sensing company in the world.
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.
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 United Kingdom Space Agency (UKSA) is an executive agency of the Government of the United Kingdom, responsible for the United Kingdom's civil space programme. It was established on 1 April 2010 to replace the British National Space Centre (BNSC) and took over responsibility for government policy and key budgets for space exploration; it represents the United Kingdom in all negotiations on space matters. The Agency "[brings] together all UK civil space activities under one single management". It is based at the former BNSC headquarters in Swindon, Wiltshire.
ARTES 20 Integrated Applications Promotion (IAP) is a European Space Agency programme that supports the development of services utilizing two or more space assets, such as satellite navigation, communication or earth observation, with terrestrial systems. Projects are focused on creating user-driven applications around solving particular problems or opportunities instead of creating a technological solutions.
Telespazio UK Ltd. is a British space company based in Luton, Bedfordshire. Founded in 1978 by a small group of engineers at the European Space Operations Centre (ESOC) in Darmstadt, Germany, VEGA presently works with various space agencies, satellite operators and manufacturers around the world. It works with the European Space Agency (ESA) and ESOC in Germany, European Space Research and Technology Centre (ESTEC) in Noordwijk, the Netherlands, ESA Centre for Earth Observation (ESRIN) in Rome, Italy, and European Space Astronomy Centre (ESAC) in Madrid, Spain.
Olympus-1 was a communications satellite built by Astrium and Thales Alenia Space, along with Fokker and SPAR Aerospace, for the European Space Agency. At the time of its launch on 12 July 1989, it was the largest civilian telecommunications satellite ever built, and sometimes known as "LargeSat" or "L-Sat". The satellite had a series of unfortunate accidents in orbit and went out of service on 11/12 August 1993. The first accident was the loss of ability to articulate the satellite's solar arrays. This was later followed by the loss of an on-board gyro during the height of the Perseid meteor shower. The satellite spun out of control and efforts to stabilise it resulted in the expenditure of the majority of its fuel. Subsequently, it was moved to a GEO disposal orbit and was put out of commission. The same manufacturers made the Alphabus satellite bus, using lessons learned from the Eurostar and Spacebus programs, and acting very much in the same way as Olympus. However, only one was constructed for Inmarsat.
Inmarsat-4A F4, also known as Alphasat and Inmarsat-XL, is a large geostationary communications I-4 satellite operated by United Kingdom-based Inmarsat in partnership with the European Space Agency. Launched in 2013, it is used to provide mobile communications to Africa and parts of Europe and Asia.
Laser communication in space is the use of free-space optical communication in outer space. Communication may be fully in space or in a ground-to-satellite or satellite-to-ground application. The main advantage of using laser communications over radio waves is increased bandwidth, enabling the transfer of more data in less time.
Electra is a satellite development project initiated by the European Space Agency (ESA) as the first partnership project under its ARTES-33 programme. In conjunction with satellite operator SES and satellite builder OHB Systems, the Electra project seeks to develop, launch and validate in orbit an electric-only propulsion platform for geostationary communications satellites of below 3 tonnes launch mass. Electra encompasses both a coordinated effort to develop a European full electric propulsion small geostationary satellite, and the implementation of a mission by SES providing flight heritage and in-orbit demonstration of the platform to gain market acceptance for the product.
Sentinel-4 is a European Earth observation mission developed to support the European Union Copernicus Programme for monitoring the Earth. It focuses on monitoring of trace gas concentrations and aerosols in the atmosphere to support operational services covering air-quality near-real time applications, air-quality protocol monitoring and climate protocol monitoring. The specific objective of Sentinel-4 is to support this with a high revisit time over Europe.
The European Union Agency for the Space Programme (EUSPA) is a space agency, managing the European Union Space Programme as one of the agencies of the European Union (EU). It was initially created as the European Global Navigation Satellite Systems Supervisory Authority (GSA) in 2004, reorganised into the European Global Navigation Satellite Systems Agency in 2010, and established in its current form on May 12, 2021. EUSPA is a separate entity from the European Space Agency (ESA), although the two entities work together closely.
Eutelsat Quantum is a communications satellite developed in the framework of a public-private partnership between the European Space Agency, Eutelsat and Airbus Defence and Space. Operated by Eutelsat, its design allows for it to reconfigure its radios coverage zone and alter its performance according its needs. It is located in a geostationary orbit and its longitude may be modified to cover any region in the world.
The domain of international space politics gained significant traction during the Cold War. This was largely fuelled by the ongoing space race between the USA and the USSR. At this time in history, space exploration was an endeavour largely restricted to the global superpowers and seemed out of reach for many smaller, developing, nations to actively participate in. Subsequently, public concerns for the cost of research and development into novel space technologies did not receive sufficient policy and academic attention in Africa. As the Cold War reached its conclusion, political power began to diffuse across the world, and this led to many smaller nation states developing national and regional space capabilities. In the context of Africa, Nigeria, Algeria, Egypt and South Africa were the front-runners in terms of investments into space-related research and development.
