About this launch
Glonass-K are the third generation of satellite design for GLONASS satellite navigation system. GLONASS is a Russian space-based navigation system comparable to the similar GPS and Galileo systems. This generation improves on accuracy, power consumption and design life. Each satellite is unpressurized and weighs 935 kg, and has an operational lifetime of 10 years.
