System for monitoring, recording and status of GNSS signals

A project for implementation of system for monitoring, recording and status of signals transmitted by satellite navigation systems (GNSS), used for air navigation in the delegated airspace of the Republic of Bulgaria, is underway. The system for monitoring, recording and status of GNSS shall perform recording of the received satellite navigation signals in several points in the country, as well as analysis and signalization of the status of the respective GNSS.

The installation and putting into operation of this system shall enable the fulfillment of ICAO requirements for application of different flight procedures and more specifically – approaches, such as RNP APCH, APV-SBAS, etc. In the conditions of increased air traffic this will allow more flexible and safe use of airspace.
