Soyuz-2.1b - Glonass-K1 No. 16L

Start time:

GLONASS-K (Global Navigation Satellite System) is the latest modification of the satellite that is part of the Russian radio navigation satellite system GLONASS. Developed by the Reshetnev ISS (Reshetnev Information Satellite Systems) and first launched on February 26, 2011, it is a significant improvement over the previous second-generation GLONASS-M satellites with longer service life and greater accuracy. GLONASS-K is the first non-pressurized GLONASS satellite - all of its equipment is capable of operating in a vacuum. Thanks to this, the mass of the satellite was significantly reduced: GLONASS-K has a mass of only 935 kg compared to its predecessor GLONASS-M, which had a mass of 1450 kg. The service life of the new satellite is 10 years, three years longer than that of GLONASS-M and seven years longer than that of the original GLONASS satellite. The power supply of GLONASS-M was also increased from 1400 W to 1600 W. GLONASS-K will transmit additional navigation signals to improve the accuracy of the system. The existing FDMA signals, 2 military and 2 civil, will be transmitted on the L1 and L2 bands, while additional civil CDMA signals will be transmitted on the L1, L2, L3 and L5 bands.
