FocalPoint D-Tail

D-Tail is an application- or OS-level software product for smartphones and wearables that enables ubiquitous positioning indoors and outdoors.
  • Centimetre-level precision
  • No beacons or additional infrastructure required
  • 30x lower battery usage for AR applications

D-Tail is designed as a complement to our foundational S-GNSS, but also works independently on existing devices. It can run as a cloud-based solution or in real time on devices at the application or hardware level.

It can detect and report movements at the centimetre level for smartphones and wearables indoors and outdoors, without requiring any additional infrastructure such as beacons and wifi.

D-Tail enables today's smartphones and wearables to achieve centimetre-level precision that in turn enables next generation products and services - from ubiquitous indoor wayfinding to high performance sports trackers and last-metre delivery.

It operates at 200 times the measurement rate of GPS, using GNSS, sensor fusion and machine learning to provide an exact and detailed trace of a user's motion across four dimensions - enabling real time measurement of motion, trajectory and gait

It substantially surpasses the levels of detail and accuracy provided by simple dead-reckoning and WiFi fingerprinting.
