Cosmos 2522, launched in 2017, is one of the later GLONASS-M satellites, part of the ongoing replacement cycle keeping Russia's fully restored navigation constellation at operational strength as the system approaches transition to the newer GLONASS-K generation, which adds CDMA signals compatible with the same broadcasting method GPS, Galileo, and BeiDou all use. GLONASS-K, the next-generation satellite already flying test units alongside satellites like this one, adds CDMA signals matching the broadcast method GPS, Galileo, and BeiDou all use — a long-overdue technical convergence expected to make GLONASS chips cheaper and more common in ordinary consumer devices.
