KPT — Korea Positioning Technology

KTAG

Continuous location from open sky to indoor space.

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

Beyond a GNSS tracker

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

Positioning intelligence on the device

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

Motion data is processed on the wearable itself, reducing the need to continuously transmit raw inertial data.

LIVE ESTIMATION

A thousand guesses. One position.

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.

Illustration. Each dot is a candidate position; the bright point is the estimate that follows the wearer.
