Russia stopped the military operations of US of Global Positioning System (GPS) stations in Russia and Crimea on June 1.
The move comes as response to Washington's anti-Russia sanctions and its refusal to plant Glonass ground base stations on the US territory.
"We have worked out and implemented measures that exclude the use of these stations for military purposes. Now they are under our full control," Russian Deputy Prime Minister Rogozin tweeted.
Rogozin also said that Moscow has initiated talks with the US on the deployment of Glonass stations on the US territory. The talks are expected to last until August 31, and "new decisions will be made" afterwards.
Glonass is the Russian equivalent of GPS, designed for military and civilian use.
