Introduction

The AH/VG610B is a high reliable, vibration-rejecting solid state Inertial Mesurement Unit. It consists of three vibrating ring gyroscopes and three inernal damping accelerometers mounted orthogonally in each axis of space. Each device is factory calibrated over the working temperature range. The fusion of the sensors is performed with an extended Kalman filter to provide the optimal estimation of dynamic roll and pitch angles. The AH/VG610B is available in standard and high range sensor configurations.

The AH/VG610B is featured with a high performance vibration isolation mechanism to provide excellent reliability under vibration and shock assistance.

The AH/VG610B can accept extermal electronic compass (module number TBD) to provide optimized heading angle. GPS aided cersion is also available upon request.
