K-NAV
Introducing Our Advanced INS Sensor with Dual Antenna GNSS

K-NAV, a dual-antenna GNSS-based positioning system, assisted by Inertial Navigation System (INS), delivers high-precision real-time position, velocity, and attitude information (heading, roll, and pitch). By integrating GNSS and IMU sensors through a sensor fusion approach, the system provides stable and reliable navigation data even under challenging environmental conditions.
