The Geo-IK-2 is a Russian series of new generation military[1] geodesy satellites replacing the Soviet Union's Geo-IK[2] and Sfera[3] constellations.
They are intended to be used to create high precision three-dimensional maps of the Earth's surface, and to monitor plate tectonics.
The satellites are produced by ISS Reshetnev, and have a mass of around 1,400 kilograms (3,100 lb).
[4] They operate in a circular orbit at an altitude of around 1,000 kilometres (620 mi) above the Earth's surface.
Not to be confused with the Napryazhenie / 14F150 / Nivelir military geodesy satellites.
