Associated space launch
Glonass-K2 are the fourth 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 1645 kg, and has an operational lifetime of 10 years.
FREGAT R/B was lifted into orbit during the mission ‘Soyuz 2.1b/Fregat-M | Glonass-K2 No. 14 (Kosmos 2584)’, on board a Soyuz 2.1b/Fregat-M space rocket.
The launch took place on March 2, 2025, 10:22 p.m. from 43/3 (43L).
