A Soyuz 2.1b/Fregat rocket successfully launched from Plesetsk Cosmodrome on August 24, 2026, carrying Glonass-K1 No. 19 into orbit. The mission deployed a third-generation navigation satellite for Russia's GLONASS satellite positioning system, which provides global navigation capabilities comparable to the American GPS and European Galileo constellations. The Glonass-K1 satellite represents a modernized design iteration with improved accuracy, reduced power consumption, and an extended operational lifespan compared to earlier generations.

The Soyuz 2.1b/Fregat vehicle lifted off from Russia's primary northern launch facility at Plesetsk Cosmodrome in northwestern Russia. This combination has proven itself as a reliable workhorse for deploying navigation satellites to their required orbital altitudes. The unpressurized satellite payload weighs 935 kilograms and is designed to maintain operational performance for approximately ten years in orbit.

The launch proceeded successfully, adding another operational satellite to the GLONASS constellation to maintain and enhance coverage of the Russian navigation network. With this deployment, Russia continues augmenting its independent space-based navigation infrastructure for global positioning and timing applications serving military and civilian users worldwide.
