COSMOS 2529 (757)

Russian Navigation Satellite (GLONASS-M) · Russian Aerospace Forces

Cosmos 2529, launched in 2019, is a GLONASS-M satellite maintaining constellation strength during Russia's ongoing transition toward the modernized GLONASS-K generation, which will eventually replace every GLONASS-M satellite currently in orbit with spacecraft carrying longer design lives and GPS/Galileo-compatible CDMA signals. Russia now operates GLONASS ground stations not just domestically but at a facility in Antarctica and aboard tracking ships, part of a global monitoring network built to keep the constellation calibrated without depending on any foreign-operated ground infrastructure.
