GLONASS-K2
From Wikipedia, the free encyclopedia
GLONASS-K2 is the next-generation satellite design intended to support the Russian GLONASS radio-based satellite navigation system. Developed by ISS Reshetnev (Reshetnev Information Satellite Systems), the first satellite was successfully launched on 7 August 2023 from the Plesetsk Cosmodrome with an expected production period of ten years. It is an evolution of the previous GLONASS-K third-generation satellites, adding CDMA signals, improving accuracy and increasing power. It is 70% heavier and has 170% more power.[1]
