Kosmos 2501 (Russian: Космос 2501 meaning Cosmos 2501), also known as Glonass-K1 No.12L is a Russian navigation satellite which was launched in 2014. The second Glonass-K satellite to be launched, it is the second of two Glonass-K1 spacecraft which will serve as prototypes for the operational Glonass-K2 spacecraft.[2]

Kosmos 2501 is a 935 kilograms (2,061 lb) satellite, which was 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 will broadcast signals in the L1, L2 and L3 navigation bands for Russian military and commercial users.[2] In addition to its navigation payloads, the satellite also carries a Cospas-Sarsat search and rescue payload.[2]

The satellite is located in a medium Earth orbit with an apogee of 19,279 kilometres (11,979 mi), a perigee of 19,715 kilometres (12,250 mi), and 64.8 degrees of inclination.[3] It is equipped with two solar panels to generate power, and is expected to remain in service for ten years.

Kosmos 2501 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 21:52:26 UTC on 30 November 2014.[4] The launch successfully placed the satellite into a Medium Earth orbit. It subsequently received its Kosmos designation, and the international designator 2014-075A. The United States Space Command assigned it the Satellite Catalog Number 40315.
