EKS (satellite system)
EKS ( Russian Единая космическая система Unified Space System , GRAY index : 14F142) is a Russian early warning satellite system for the detection of rocket launches.
The three-axis stabilized satellites of this type (also called Tundra) are intended to replace the old satellites of the Oko series. A single EKS satellite should be able to replace five to six Oko satellites. The satellites are also said to carry secured emergency communications technology in the event of a nuclear war. They are intended to complement the Voronezh-DM type earth-based early warning systems.
The development of the satellites began in 2000. In 2007 the Russian government commissioned RKK Energija to build the first satellite. The first launch should take place in 2009, but was delayed until the end of 2015.
