POSITIONING CONTINUITY
One journey. Different signals. Continuous intelligence.
Satellite positioning works best under open sky. Indoor spaces, dense urban environments and complex structures require different information. KPT brings multiple positioning sources together so the location experience can continue as the environment changes.
OUTDOOR01
- GNSS
- RTK GNSS
Start with global positioning.
Use GNSS — and RTK GNSS where higher precision is required — as the outdoor reference.
TRANSITION02
- Sensor Fusion
- Environment Detection
Understand the change of environment.
Combine sensing and positioning intelligence to recognize when outdoor assumptions are no longer enough.
INDOOR03
- Inertial
- Wi-Fi
- Map
- Pressure
Keep estimating motion and position.
Use Wi-Fi, inertial sensing, pressure, map information and other available signals to maintain indoor location awareness.
KPT TECHNOLOGY
A positioning stack built for the physical world.
Location is not one sensor. KPT connects signals, edge intelligence, sensor fusion and positioning engines into systems that can serve people, assets and autonomous machines.
