The first two In Orbit Validation satellites of the Galileo constellation. The Galileo constellation is ESA's satellite navigation system and is expected to be completed by 2020. Galileo will provide Europe with an alternative to the American GPS and Russian GLONASS constellations, but will be interoperable with both systems. First launch of the Soyuz rocket from the Guiana Space Centre.
Medium Earth OrbitGlonass-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.
