Nigerian airspace has switched from terrestrial air navigation to a satellite-based navigation system, known as Global Navigation Satellite System (GNSS).
The scheme was introduced in Lagos, as well as at three other major airports: Kano in northern Nigeria, Nnamdi Azikiwe International Airport in the capital Abuja, and Port Harcourt in the south.
Lagos was the first Nigerian airport to report the success of GNSS, after Emirates Airlines used the satellite navigation technology to land. This was followed by a KLM satellite navigation-assisted landing in Kano.
The goal of the advanced technology – which requires minimal contact with air traffic controllers and is in use increasingly in the world’s airports – is a single, universal air navigation system
