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

Complex in-house environments for instance, air-ports and departmental stores is often a pain to find your way around. And even though Google is seeking phones with 3D detectors as one prospective fix for places GPS won’t correctly reach, another approach is to kit out an interior with quite a lot of Bluetooth beacons – giving smartphone users located-locked pings to fix onto to recognise where they are.

The UK’s second busiest airport, Gatwick, has went for the latter method to power an indoor navigation system it’s launching as a section of a larger, multi-year transformation program.

It’s now finished kitting out its two terminals with around 2,000 battery-powered beacons to make certain that digital map users will get a more exact blue dot as they stroll around. The beacon system will likewise be employed to power an augmented reality wayfinding tool – so that mobile users can be guided to precise locations in the terminals using on-screen arrows. The beacon system is slated as backing up positioning with +/-3m accuracy.

Gatwick is intending to integrate indoor positioning into some of its mobile apps, and says it’s in discussions with airlines to utilize it for their own mobile apps and services – giving example of them being able to send push notifications to warn people if they’re running late, or even make a decision on whether or not to wait or offload luggage so an airplane can take off punctually.

Retail stores and other third parties will likewise be able to use the system for proximity detection of potential clients and push promoting messages – as a minimum to those who have opted in to receive them.

Gatwick says it won’t be gathering up any personal data with the beacons but says “generic information on ‘people densities’ in different beacon zones” will be employed to assist in improving airport operations – for instance, queue measurement, streamlining passenger flows and lessening traffic jam.

The airport has worked with UK startup company 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 enable third parties to access the functionality.
