GLONASS-K
GLONASS-K is the latest satellite design intended as a part of the Russian GLONASS radio-based satellite navigation system. Developed by 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.
== History ==
(詳細はRussian Federal Space Agency (Roscosmos) initially ordered 27 GLONASS-K satellites from Reshetnev Information Satellite Systems, 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 GLONASS-K1 to start flying in early 2018, just after the launch of the first GLONASS-K2 prototype. The presentation showed at least eleven additional GLONASS-K1 satellites flying until 2020.〔
