Glonass-K satellite enters service

The first next-generation navigation satellite of the Glonass-K series, designed and built by ISS-Reshetnev Company, has started providing services in orbit.

The decision to put the new Glonass-K №12L into service was made following the results of its in-flight tests which had lasted for more than a year – from the satellite’s launch on December 1, 2014.

This Glonass-K satellite was built around an unpressurized platform, has a mass of 974 kg, electric power supply system’s capacity of 1600 W and was designed for a 10-year lifespan. It transmits five navigation signals in the L1, L2 and L3 bands. Apart from that, Glonass-K carries a COSPAS-SARSAT payload supporting the international satellite-based search and rescue system.

For the long term, subsequent Glonass-K satellites are expected to considerably improve the characteristics and capabilities of the GLONASS system. Glonass-K satellites will gradually replace ageing satellites of the Glonass-M series that today form the backbone of the system’s orbital constellation.

All satellites which are part of the GLONASS system were developed and constructed at Information Satellite Systems – Reshetnev Company.

As of today, there is one more next-generation satellite Glonass-K №11L in the orbital constellation of the GLONASS system. It was launched into orbit on February 26, 2011, has already undergone in-flight tests and is ready to provide services.
