Cost Effective Dynamic Measured IMU For Navigation Positioning Using

Introduction

AH/VG610B is a high reliable, vibration-rejecting solid state inertial measurement unit. It is consist of three vibrating ring gyroscopes and three internal damping accelerometers mounted orthogonally in each axis of space. Each divice 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.
AH/VG610B is featured with a high performance vibration isolation mechanism to provide excellent reliability under vibration and shock conditions.
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 128k SPS of each sensor.
• Data rate up to 250 packets per second.
• User-friendly RS232 digital interface.
• Low power consumption, typical 0.25A @12V
• Complete against crossbow VG440.

Applications

• Unmmanned helicopters and light helicopters
• UAV and AGV
• Platform stabilization
• Vessel applications
• Inertial navigation systems

Note: subject to change without notice, unless requested
Warning: placing the AH/VG beyond the specificaiton may damage the device temporarily or permannetly.
