Elektro-L n°4

Elektro-L n°4 is a Russian geostationary weather satellite. It is the fourth Elektro-L spacecraft to fly. It replaces the first Elektro series, which was never brought to operational service. The Elektro-L satellites are based on Lavochkins Navigator-Bus. Elektro-L also features receivers for the SARSAT-COSPAS emergency call system. The MSU-GS scanner is the primary instrument aboard the spacecraft. It is designed to produce visible light and infrared images of a full disc of the Earth. It can produce an image every half-hour, with visible light images having a resolution of one kilometre, and infrared images having a resolution of four kilometres. The satellite also carries GGAK-E, a heliophysics payload designed to study radiation from the Sun. The satellite will also be used to relay data between Russian weather stations, and will also be used to relay signals as part of the Cospas-Sarsat system. It carries seven infrared channels and three visible channels.
