KTAG
A connected positioning wearable designed to combine outdoor GNSS with motion sensing and sensor-fusion positioning as people move into complex indoor environments.

BEYOND GNSS
KTAG is designed around multiple positioning inputs. Outdoors, GNSS provides a global location reference. As the environment changes, onboard motion sensing, pressure information, sensor fusion and cloud positioning can contribute to the location solution.
The goal is not simply to report a last known GPS point. It is to support location continuity as the user moves between environments.
EDGE INTELLIGENCE
Processing motion locally reduces the need to continuously transmit raw inertial data and makes real-time motion estimation possible directly on the wearable.
Raw inertial data
Continuous acceleration and rotation samples

On the wearable
Real-time motion estimation
Location updates
Compact motion results to transmit
LIVE ESTIMATION
Inside KTAG, every step starts a quiet contest. Countless candidate positions move with the wearer, and each stride, signal and wall of the building decides which of them survive. What remains is where the wearer is — continuously, from open sky to the far corner of a building.
