In 2022, Russia launched the 51st Glonass-M satellite, completing a 20-year history. These satellites have been providing navigation signals in two frequency bands, L1OF and L2OF, to civil users since 2011.

The GLONASS-K satellite, transmitting a CDMA signal in the L3 band, inaugurates a new era of radionavigation signals for both the Russian system and for international GNSS interoperability. As demand for high-precision services through dual- or triple-frequency user equipment increases, GLONASS will come to the forefront. The 2014 GLONASS-K2 satellite will have an FDMA signal in the L1 and L2 bands and CDMA signals in L1, L2, and L3. The overall constellation update will be completed in 2021. Another 2014 launch will fill the Russian SBAS orbit constellation with three geostationary space vehicles.
