Satellite radio navigation systems provide millimeter accuracy in measurement on a global level. They are used for fundamental research, continents drift and the Earths poles movement observation, in geodesy and cartography for cadastres and digital maps development. The satellite systems possess the high priority in the navigation and control of the aviation, marine and terrestrial transport means.
Monitoring of navigation field
Navigation satellites generate and create a navigation field in the near Earth space at altitude of about 20 thousand km. Its monitoring has to confirm the navigation system accuracy, integrity, continuity and operational readiness.

Developed equipment for monitoring of navigation field allows us to assess in real time accuracy, integrity, non-stop service, and operational readiness for GPS, GLONASS, GALILEO, SBAS, GBAS systems.
Global satellite navigation systems resistance to jamming
Satellite navigation signal intensity on the Earth surface is made up of 10-16 W, and any signal exceeded this level can lead to incorrect coordinates evaluation. Antenna arrays make possible removal of signal-interference by means of special shape pattern formation.
