WARSAW — The Russian Ministry of Defense has launched a project aiming to secure Glonass, the country’s satellite navigation system, against enemy disruptions of signals, state-run news agency ITAR-TASS reported.


The ministry has handed a 350 million ruble (US $11 million) contract to two local entities, the Russian Scientific-Research Institute of Physical-technical and Radiotechnical Measurements (VNIIFTRI) and NAVIS navigation systems. The two contractors are to increase the system’s immunity to electronic warfare.


Under the plan, VNIIFTRI and NAVIS will set up a facility to test the system’s resistance by mimicking noise that can jam the satellite signal aimed at land- and air-based Glonass receivers. The aim is to teach the system to distinguish noise from signals and bypass it.


The system was developed by the then-Soviet Ministry of Defense beginning in 1976 as an alternative to the US-controlled Global Positioning System. The first Glonass satellite was launched on Oct. 12, 1982.


Currently, the system is operated by 23 fully operational satellites. Russia says that Glonass provides full global coverage.


Meanwhile, Moscow is aiming to involve other countries in joint strategic cooperation on the navigation system. In December 2012, India and Russia signed a memorandum of understanding to collaborate on the Glonass program.
