The ArSys® is rugged hybrid GNSS/Inertial system answering the needs for Heading & Attitude measurement for both static and dynamic applications.
The ArSys® utilize advanced accurate GNSS-based Heading system with 2 highly accurate antennas along with 9-DoF IMU (3 x Accelerometers 3 x Gyro 3 x Magnetometer) in order to be able to provide accurate Roll/Pitch/Yaw angles in every environment. Powerful advanced 27-State UKF (Unscented Kalman Filter) algorithm fuses information from all sensors together to bring compensated attitude & heading data.
PowerFull Processor provides 1.0 GFLOPS to allow the massive floating-point calculations. The combination of both technologies, the GNSS-Based heading technology which provides accurate heading information also in ferro-magnetic environment along with IMU system and proprietary advanced algorithm, provides these excepional perfoemence.
