Kosmos 2471 is a 935 kg satellite built by ISS Reshetnev based on the Ekspress-1000A satellite bus. The spacecraft has three-axis stabilisation to keep it in the correct orientation, and broadcast signals in the L1, L2 and L3 navigation bands for Russian military and commercial users.[4] In addition to its navigation payloads, the satellite also carries a Cospas-Sarsat search and rescue payload.[4]

The satellite is located in a medium Earth orbit with an apogee of 19,150 km (11,900 mi), a perigee of 19,121 km (11,881 mi), and 64.8° of inclination.[5] It is equipped with two solar panels to generate power. It entered service by the end of 2011.[6]

Kosmos 2471 was launched from Site 43/4 at the Plesetsk Cosmodrome in northwest Russia. A Soyuz-2.1b carrier rocket with a Fregat upper stage was used to perform the launch, which took place at 03:07:15 UTC on 26 February 2011.[7] The launch successfully placed the satellite into a Medium Earth orbit. It subsequently received its Kosmos designation, and the International Designator 2011-009A. The United States Space Command assigned it the Satellite Catalog Number 37372.[8]

Kosmos 2471 remained in service for ten years. On 11 November 2021, the satellite was decommissioned and removed from the operational GLONASS constellation.[2]
