Essaim (satellite) : ウィキペディア英語版 | Essaim (satellite) Essaim (''swarm'', in French) is a French military reconnaissance microsatellite constellation. Its main purpose is to collect and map signals intelligence across the world. The DGA describes it as a "vacuum cleaner for () waves". == Description == Essaim is a constellation of four 120 kg micro satellites (including one spare) in low earth orbit. They are demonstration models which were supposed to last three years. They fly separated by a few hundreds of kilometers. Missions are designed by the ''Celar'' (Centre d'électronique de l'armement) in Bruz, near Rennes and are uploaded from CNES in Toulouse to the constellation. Collected data follows the same path in reverse order.
