Britain’s Gatwick Airport now has 2,000 beacons for in-house navigation

Complex in-house environments for example, air-ports and department stores could be a headache to find your way around. And even while Google is seeking smartphones with 3D detectors as one probable solution for places GPS won’t correctly reach, another approach is to kit out an interior with a whole lot of Bluetooth beacons – giving phone users located-locked pings to fix onto to recognise where they’re.

The UK’s second busiest airport, Gatwick airport, has selected the second method to power an indoor navigation system it’s launching as an element of a wider, multi-year transformation program.

It’s currently finished kitting out its two terminals with about 2 Thousand battery-powered beacons to make certain digital map users will get a more accurate blue dot as they stroll around. The beacon system will likewise be utilized to power an augmented reality wayfinding tool – to ensure that mobile users can be guided to specific locations inside the terminals via on-screen arrows. The beacon system is scheduled as supporting positioning with +/-3m precision.

Gatwick is looking to integrate indoor positioning into some of its mobile apps, and says it’s in discussions with airlines to make use of it for their own mobile apps and services – giving instance of them the ability to send push notifications to advise travellers if they’re running late, or even consider whether or not to wait or offload luggage so an airplane can take off promptly.

Retailers and other third parties will likewise be able to utilize the system for proximity detection of potential buyers and delivery advertising messages – as a minimum to those who’ve signed up to receive them.

Gatwick says it certainly won’t be collecting any personal data through the beacons but says “generic information on ‘people densities’ in different beacon zones” will be used to assist in improving airport operations – including queue measurement, streamlining passenger flows and reducing obstruction.

The airport has worked with UK start-up Pointr on the system. And also developing software and managing the system on an ongoing basis, Pointr provides an SDK with support for 3D AR wayfinding to allow third parties to get into functionality.
