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. [1]
The satellite was launched on 30 July 2021 by an Ariane 5 rocket, together with the Brazilian Star One D2 satellite. Quantum is Eutelsat's 36th and Airbus Defence and Space's 132nd satellite launched by Arianespace. [2]
The satellite uses conventional chemical thrusters. The payload, which operates in the Ku-band, has a power rating of 5 kW. A key component of the satellite is its phased-array antenna, which was produced by Airbus's Spanish division CASA. [1]
The payload allows for the redefinition of its Ku-band beams with configurable coverage in order to follow targets (ships, aircraft, vehicles, troops) and provide them with mobile communications.
Besides coverage, bandwidth may also be modulated in terms of power and frequencies. The satellites also offers detection mitigation measures against radio jamming.
Finally, the high responsiveness will also bring benefits to governments in the event of natural disasters or surveillance operations. [3]
The contract establishing the public-private partnership between ESA, Eutelsat and Airbus Defence and Space was signed on 9 July 2015 in the offices of the European Centre for Space Applications and Telecommunications in Harwell, near Oxford in the United Kingdom. It established the role of Eutelsat in the exploitation and commercialization of the new satellite, and Airbus's in the design and production. Airbus designs the payload in its premises in Portsmouth using the new “GMPT” platform developed in Guildford by its Surrey Satellite Technology subsidiary. This project is supported by ESA and the UK Space Agency in the scope of the ARTES programme for a launch initially planned for 2019. [4] [5]
The development of the antenna is delayed and requires four years to the CASA division of Airbus and its industrial partners (CRISA, Arquimea and GMV [6] ) with the support of the Industrial Centre for Technology Development (CDTI). The Ku-band active antenna, featuring eight independent reconfigurable beams, is unveiled in Madrid on 21 November 2019 and named ELSA+ (ELectronically Steerable Antenna+). The conducted works rely on previous accomplishments of Airbus in this field, especially the DRA/ELSA instrument designed for Hispasat 36W1, the IRMA (In-orbit Reconfigurable Multibeam Antenna) antenna for the Spainsat military satellite, and Gaia's active antenna. [7]
Quantum was assembled and tested between 2019 and 2020 in the premises of Airbus DS in Toulouse, [8] from where it was sent on 30 June 2021 to the Guiana Space Centre, before being launched successfully on 30 July 2021 on board Ariane 5 flight VA254. [9] [10]
Ariane 5 is a European heavy-lift space launch vehicle developed and operated by Arianespace for the European Space Agency (ESA). It is launched from the Centre Spatial Guyanais (CSG) in French Guiana. It has been used to deliver payloads into geostationary transfer orbit (GTO) or low Earth orbit (LEO). 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.
Arianespace SA is a French company founded in 1980 as the world's first commercial launch service provider. It undertakes the operation and marketing of the Ariane programme. The company offers a number of different launch vehicles: the heavy-lift Ariane 5 for dual launches to geostationary transfer orbit, the Soyuz-2 as a medium-lift alternative, and the solid-fueled Vega for lighter payloads.
Ariane is a series of European civilian expendable launch vehicles for space launch use. The name comes from the French spelling of the mythological character Ariadne. France first proposed the Ariane project and it was officially agreed upon at the end of 1973 after discussions between France, Germany and the UK. The project was Western Europe's second attempt to develop its own launcher following the unsuccessful Europa project. The Ariane project was code-named L3S.
The Guiana Space Centre, also called Europe's Spaceport, is a European spaceport to the northwest of Kourou in French Guiana, a region of France in South America. Kourou is located approximately 310 mi (500 km) north of the equator, at a latitude of 5°. In operation since 1968, it is suitable as a location for a spaceport, because of its equatorial location and open sea to the east.
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.
Vega is an expendable launch system in use by Arianespace jointly developed by the Italian Space Agency (ASI) and the European Space Agency (ESA). Development began in 1998 and the first launch took place from the Centre Spatial Guyanais on 13 February 2012.
Surrey Satellite Technology Ltd, or SSTL, is a company involved in the manufacture and operation of small satellites. A spin-off company of the University of Surrey, it is presently wholly owned by Airbus Defence and Space.
ELA-3, is a launch pad and associated facilities at the Centre Spatial Guyanais in French Guiana. ELA-3 is operated by Arianespace as part of the expendable launch system for Ariane 5 launch vehicles. As of September 2022, 114 launches have been carried out from it, the first of which occurred on 4 June 1996.
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.
Hot Bird 7 was a communications satellite that lost in a launch failure in 2002. Intended for operation by Eutelsat, it was to have provided direct-to-home broadcasting services from geostationary orbit as part of Eutelsat's Hot Bird constellation at a longitude of 13° East. Hot Bird 7 was intended to replace the Hot Bird 3 satellite, which had been launched in 1997.
Ariane 6 is a European expendable launch system currently under development since the early 2010s by ArianeGroup on behalf of the European Space Agency (ESA). It is intended to replace the Ariane 5, as part of the Ariane launch vehicle family. The stated motivation for Ariane 6 was to halve the cost compared to Ariane 5, and increase the capacity for the number of launches per year.
