Description
The AH/VG610B is a high reliable, vibration-rejecting state inertial meaurement unit. It consists of 3 vibration ring gyroscopes and 3 inertial 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 potimal estimation of dynamic roll and pitch angle. The AH/VG610B is available in standard and high range sensor configurations.
The AH/VG610B is featured with a high performance vibration mechanism to provide excellent reliability under vibration and shock conditions.
The AH/VG610B can accept external electronic compass(module number TBD) to provide optimized heading angle. GPS aided version is also available upon request.
Features
- consistent performance under high vibration environment
- internal vibration isolation mechanism
- fully calibrated for offset, scale factor, cross-axis sensitivity and misalignment of each axis of sensors
- temperature compensated for improved bias and sensitivity stability
- double precision extended kalman filter running at 500 cycles per second with synchronous sampling rate at 128kSPS of each other
- data rate up of 250 packets per second. user-friendly RS232 digital interface
- low power consumption, typical 0.25A@12V
- complete against crossbow VG440
Application
- unmanned helicopters and light hilicopters
- UAV and AGV
- platform stabilization
- vessel applications
- inertial navigation systems
