Essaim was a constellation of four 120 kg microsatellites (one of which was a spare) in low Earth orbit (LEO). They were demonstration models which were supposed to last three years. They flew separated by a few hundreds of kilometers. Missions were designed by the Celar (Centre d'électronique de l'armement) in Bruz, near Rennes and were uploaded from CNES in Toulouse to the constellation. Collected data followed the same path in reverse order.
