Geo-IK-2

The Geo-IK-2 is a Russian series of new generation military geodesy satellites replacing the Soviet Union's Geo-IK and Sfera 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 1400 kg. They operate in a circular orbit at an altitude of around 1000 km above the Earth's surface.

Not to be confused with the Napryazhenie / 14F150 / Nivelir military geodesy satellites.
