Altitude and Heading Reference System (AHRS) Roll, Pitch and Heading Angle in Dynamic Environments Enhanced Performance Kalman Filter Algorithm High Stability MEMS Sensors High Range Gyro and Accel Options
The AHRS400CA is a high performance, solid-state attitude and heading reference system intended
for airborne applications such as UAV control, Avionics, and Platform Stabilization. This high reliability, strap-down inertial subsystem provides attitude and heading measurement with static and
dynamic accuracy comparable to traditional spinning mass vertical and directional gyros.
This AHRS400 series product builds on the performance of the AHRS300 series. It features higher performance sensors, including silicon MEMS accelerometers and gyroscopes with lower noise and improved bias stability.
The AHRS400CA achieves its excellent performance by employing proprietary Kalman Filter algorithms to determine stabilized roll, pitch, and heading angles in static and dynamics conditions. The Kalman Filter implementation results in a continuous on-line gyro bias calibration, and an adaptive attitude and heading measurement that is stabilized by the long term gravity and magnetic north references. Output data is provided in both analog and digital (RS-232) formats.
Each Inertial System comes with a User’s Manual offering helpful hints on programming, installation, and product information. In addition, the GYRO-VIEW software is included to assist you in system development and evaluation, and allows you to perform data acquisition.
