## Why It Matters
Cosmos 1594 is part of the original GLONASS family of navigation satellites, a program intended to provide satellite navigation capabilities. As an element launched in 1984, it represents a unit of the early deployment of the GLONASS constellation and contributes to the history and continuity of Soviet/Russian satellite navigation efforts. The mission used a Proton-K launch vehicle with a Blok DM-2 upper stage, illustrating the launch architecture employed for GLONASS deployments of that period. Identifiers such as SCN 15260 and COSPAR 1984-095B allow the satellite to be tracked and referenced across catalogues and databases. For researchers, historians, and satellite operators, Cosmos 1594 is a verifiable datum point in the sequencing of GLONASS launches and in the operational record of Proton-K/Blok DM-2 launch campaigns from Baikonur Site 200.

## Notable For
