ELISA 2
ELISA (ELectronic Intelligence by SAtellite) is a suite of four French military satellites launched on 17 December 2011 from Arianespace's Kourou spaceport in French Guiana. It consists of microsatellites ELISA 1 (or ELISA W11, COSPAR ID: 2011-076A), ELISA 2 (or ELISA E12, COSPAR ID: 2011-076D), ELISA 3 (or ELISA W23, COSPAR ID: 2011-076C), and ELISA 4 (or ELISA E24, COSPAR ID: 2011-076B) The entire ELISA suite was launched on a single Soyuz ST-A launch vehicle, along with Pléiades-1 and SSOT. The ELISA programme is a demonstrator meant to pave the way for a planned Signals intelligence constellation called CERES. The ELISA satellites are in a Low Earth orbit a few kilometres from each other to record radar and radio transmissions. Since 2014, they are used as a pre-operational system. The satellites are built around the Myriade microsatellite bus. See also * ESSAIM - another French military SIGINT microsatellite project * CERES Ceres most commonly refers to: * Cere ...

Military Satellites
A military satellite is an artificial satellite used for a military purpose. The most common missions are intelligence gathering, navigation and military communications. The first military satellites were photographic reconnaissance missions. Some attempts were made to develop satellite based weapons but this work was halted in 1967 following the ratification of international treaties banning the deployment of weapons of mass destruction in orbit. As of 2013, there are 950 satellites of all types in Earth orbit. It is not possible to identify the exact number of these that are military satellites partly due to secrecy and partly due to dual purpose missions such as GPS satellites that serve both civilian and military purposes. As of December 2018 there are 320 known military or dual-use satellites in the sky, half of which are owned by the US, followed by Russia, China and India (13).

CERES (satellite)
CERES (CapacitÉ de Renseignement Électromagnétique Spatiale) is a French space-based electronic surveillance constellation designed to collect intelligence of electromagnetic origins anywhere in the world. Consisting of three formation-flying satellites, it was developed by Airbus Defence and Space and Thales Alenia Space under the management of the CNES for the French defence procurement agency ( DGA). Launched in November 2021, the satellites are expected to reach their final orbit, 700 km from Earth, after a few months and full operational capability by the end of 2022. Their purpose is to allow France to gather data that was previously inaccessible from land, sea, or airborne sensors, and for the French military to more quickly and effectively adapt to new operational scenarios. An all-weather system operational 24/7, the CERES constellation is notably capable of tracking, identifying and mapping enemy radars, air defenses and command centers. The CERES will replace t ...

Spacecraft Launched By Soyuz-2 Rockets
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
