By 2010, GLONASS had achieved full coverage of Russia's territory and in October 2011 the full orbital constellation of 24 satellites was restored, enabling full global coverage. The GLONASS satellites' designs have undergone several upgrades, with the 2020 latest version, GLONASS-K2, scheduled to enter service in 2022. An announcement predicts the deployment of a group of communications and navigational satellites by 2040. The task also includes the delivery to the Moon of a series of spacecraft for orbital research and the establishment of a lunar communications and positioning system.
