Summary

COSMOS 1680, also known as Kosmos-1680, is a military communication satellite launched by the Soviet Union on September 4, 1985. It was deployed from the Plesetsk launch site using a Kosmos 11K65M rocket from Launch Pad LC132/1. The satellite's dimensions are a length of 3 meters and diameter of 2 meters, with a span also measuring 3 meters. COSMOS 1680 has a dry mass of 800 kilograms and was designed for a short lifetime of approximately six months. Equipped with solar cells and batteries for power supply, it operates in a cylindrical shape with an RCS (Reflective Cross Section) value of 2.0304. The satellite's mission involves military communication using the Strela-2M payload, specifically for store dump operations. Manufactured by NPOPM and owned by GUKOS, COSMOS 1680 was part of the Strela-2M bus configuration.
