Cosmos 2471



Glonass-K, also known as Cosmos 2471, was launched from Plesetsk on 26 February 2011 at 03:07 UT by a Soyuz 2 rocket. The satellite weighed 935 kg at launch. It is the first Glonass-K satellite of the Russian fleet of the Glonass navigational system. This next generation satellite is smaller than earlier platforms, will transmit more navigation signals, and has a longer design life. It has five navigation channels, four in special L1 and L2 bands and one for civilian applications in the L3 band. The design life is ten years. The Glonass constellation currently includes twenty-two operational satellites and four in maintenance. The fleet requires twenty-four operational satellites to achieve global navigation service.
