SmartPath (Ground Based Augmentation System)

Ground Based Augmentation System (GBAS), known in Australia as SmartPath, is a satellite-based precision landing system and is recognised by ICAO as a potential future replacement for current instrument landing systems (ILS).

SmartPath will be a critical component of Australia’s next-generation air traffic management infrastructure.

The system uses GPS signals to provide aircraft with very precise positioning guidance during the final stages of an approach, both horizontal and vertical, which is especially critical  during the landing phase of flight. This allows for a safer, more efficient descent and landing.

Just one SmartPath installation can guide up to 26 highly precise approach flight paths simultaneously within a 42 kilometre radius.
