Geo-IK-2 (Musson-2, 14F31)

Geo-IK-2 [ISS Reshetnev]

The Geo-IK-2 is a follow on geodesy mission to the GEO-IK series.

The Geo-IK-2 satellites feature following instruments:

  • SADKO radar altimeter
  • Laser retro reflectors
  • GLONASS and GPS receiver

The satellites are put into a 1000 km orbit by Rokot-KM, Soyuz-2-1v Volga or Angara-1.2 rockets launched at the Plesetsk cosmodrome.

The first launch on board of a Rokot-KM booster took place on 1 February 2011. The launch failed to reach the correct orbit and ground controllers were initially not able to establish contact with the satellite called Kosmos 2470. After evaluations to use the satellite from this orbit, it was finally declared a total loss in June 2011. It reentered on July 15,2013.

The second satellite was ordered to be launched in 2014, but the launch has slipped until 2016.

In August 2012, a third satellite was ordered as a replacement for the lost mission. It is planned to be launched in 2017.
