## Summary
Cosmos 1520 (also Kosmos 1520) is a GLONASS navigation satellite (instance of the original GLONASS family) that was launched on 29 December 1983. It was placed into orbit from Baikonur Cosmodrome Site 200 by a Proton-K rocket with a Blok DM-2 upper stage and is cataloged under COSPAR 1983-127B and Satellite Catalog Number 14591.

## Why It Matters
Cosmos 1520 is a component of the original GLONASS family of navigation satellites. As part of that series, it contributed to the broader GLONASS effort to deploy and maintain a satellite navigation capability. Its launch demonstrates the use of the Proton-K launch system combined with a Blok DM-2 upper stage to place navigation payloads into their intended orbits from Baikonur Cosmodrome Site 200. The satellite's registration in international catalogs (COSPAR 1983-127B; SCN 14591) and presence in reference systems such as the Wolfram Language registry make it a traceable element in historical records of GNSS deployments. For researchers, historians, and engineers tracking the evolution of GLONASS and launch logistics, Cosmos 1520 is a verifiable data point in the early operational deployment of that navigation constellation.
