Satellite navigation scales down navigation equipment

Satellite navigation scales down navigation equipment


Satellite navigation has environmental benefits: it makes possible flight paths independently of ground-based equipment such as instrument landing systems or VHF omnidirectional radio range, thus allowing more flexible routing. This results in more efficient flight routes and thus less kerosene consumption, CO2 and noise emissions.


Skyguide has already implemented over 200 such satellite-based approach procedures to date. As a result, some traditional, ground-based navigation systems can be replaced in the medium term.


The first omnidirectional beacons have already been deactivated. For example, the non-directional radio beacon in Bern will be discontinued in autumn 2020, which will save 5,000 kWh of power a year for its operation and air-conditioning.


However, some radio beacons will need to continue to be operated for safety reasons in case satellite systems fail. However, they are being re-designed, re-positioned and equipped with new technologies, which will also reduce the number of journeys needed for maintenance work.
