System for Differential Corrections and Monitoring

The System for Differential Corrections and Monitoring (SDCM), is the satellite-based navigation augmentation system operated by Russia's Roscosmos space agency to augment the precision of the GLONASS satellite navigation system.^[1] It uses the Luch Multifunctional Space Relay System to transmit correction data.^[2]

SDCM's service area covers the Russian Federation. As of 2021^[update] it had not yet been certified for use for public aviation.^[3]
