Associated space launch
Glonass-M, also known as Uragan-M, are the second generation of Uragan satellite design used 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 weighs 1415 kg, is equipped with 12 L-band antennas, and has an operational lifetime of 7 years.
SL-12 R/B(2) was lifted into orbit during the mission ‘Proton-M/DM-2 Enhanced | 3 x Glonass-M (Kosmos 2459, Kosmos 2460, Kosmos 2461)’, on board a Proton-M space rocket.
The launch took place on March 1, 2010, 9:19 p.m. from 81/24 (81P).
