GLONASS-K is the latest satellite design intended as a part of the Russian GLONASS radio-based satellite navigation system. Developed by ISS Reshetnev (Reshetnev Information Satellite Systems) and first launched on 26 February 2011, it is a substantial improvement of the previous GLONASS-M second-generation satellites, having a longer lifespan and better accuracy.

The Federal Targeted Program “Global Navigation System” 2002–2011, introduced in 2001, stipulated the development of a third-generation navigation satellite design, called GLONASS-K, as part of the overall GLONASS upgrade program in the time frame 2005–2011. The new satellite followed the second generation GLONASS-M, introduced in 2003. The Russian Federal Space Agency (Roscosmos) initially ordered 27 GLONASS-K satellites from ISS Reshetnev, the developer of all the previous GLONASS satellites. On 7 December 2010, the company announced it had completed ground tests of the first GLONASS-K satellite. The satellite was launched to orbit on 26 February 2011. On November 30, 2014, the second and supposedly last GLONASS-K1 development satellite was put to orbit as Kosmos 2501.
On a May 28, 2014, interview, Nikolay Testoyedov — president of ISS Reshetnev — stated that production of GLONASS-M would end in 2015, with GLONASS-K being exclusively produced after that final batch. In an December 14, 2014, interview with GPS World, he stated that because of Western sanctions that limited the supply of radiation resistant electronics, they had decided to launch nine additional GLONASS-K1 as fleet replacement while they finished the GLONASS-K2 design. In a May 2015 presentation, Mr. Testoyedov expected the serial production of GLON
