Gatwick has installed 2,000 indoor navigation beacons, which it says will enable augmented reality wayfinding at the airport. The London airport says that the beacons provide an indoor navigation system which is much more reliable than GPS, enabling third parties, airlines and the airport itself to develop augmented reality wayfinding tools within their apps. Gatwick said that the new navigation technology is currently being integrated into some of the airport’s apps, and it is in discussions with airlines for them to do the same.
Examples of how the technology could be used include sending out reminders to late running passengers, or finding out their location in order to make an informed decision on whether to wait or offload their luggage so the aircraft can take off on time. The airport stressed that airlines would need the consent of the passenger to do this, adding that 'No personal data will be collected by Gatwick although generic information on people densities in different beacon zones may help to improve airport operations.
