ViaNav product family consists of different systems, all based on similar technology. Each product has been produced to serve different functions with different accuracy requirements.
VIA-100 series includes different products with different functionality. VIA-100 line is composed of following products:
VIA-100I, is an Inertial Measurement Unit with 3D accelerometers, 3D gyroscopes and Magnetometer.
VIA-100A, is a 3 DOF Attitude Heading Reference System (AHRS) which provides driftless real-time orientation information over the full 360 degrees of angular motion on all three axes. It includes 3D accelerometers, 3D gyroscopes and 3D magnetometers.
VIA-100A+, is a 3 DOF AHRS which provides driftless real-time orientation information. VIA-100A+ includes a multi-IMU configuration and employs an optimum filter to lower IMU noise level. VIA-100A+ provides 3D orientation with improved accuracy and reliability.
VIA-100G, includes a VIA-100A, a GPS and a barometric altimeter with an advanced Kalman filtering algorithm providing accurate 3D position, velocity and attitude. VIA-100G is a state of the art GPS/IMU system.
