Competitive Inertial Navigation System Ahrs Sensor Ahrs Attitude Heading Reference System AHRS1000


Product Description
AHRS1000 Attitude and Heading Reference System (AHRS) is an enhanced, high performance strapdown inertial measurement system, which measures absolute orientation (Heading, Pitch and Roll) for any device on which it is mounted. Orientation is determined with high accuracy for both motionless and dynamic applications.
AHRS1000 utilizes 3-axes each of precision accelerometers,
magnetometers and gyroscopes to provide accurate Heave, Heading, Pitch and Roll of the device under measure.
Integration of gyroscopes’ output provides high frequency, real-time
measurement of the device rotation about all three rotational axes.
Accelerometers and magnetometer measure absolute Pitch, Roll and magnetic Azimuth at AHRS initial alignment as well as providing ongoing corrections to gyroscopes during operation.

FAQ
What is an AHRS?
An Attitude Heading and Reference System, better known as an AHRS, is a 3-axis sensor system that provides real-time 3D attitude position – pitch, roll, and heading. The primary function then of an AHRS is to provide orientation data. AHRS are designed to replace traditional gyro-based instruments and to provide superior reliability and accuracy.
Some of the many applications for AHRS include control and stabilization, measurement and correction, and navigation. An example of control and stabilization could be where a camera or antenna mounted on a system such as a plane or ship needs to be stable. Measurement and correction best applies to imaging systems where an AHRS is used to ensure the direction the imager is pointed. And in navigation, an AHRS can be used to provide orientation and direction.
AHRS consist of magnetometers, microelectromechanical systems (MEMS) accelerometers, and MEMS gyroscopes on all three axes. In other words, a MEMS-based AHRS includes sensors for 3-axis magnetic, 3-axis acceleration, and 3-axis gyro. These sensors, combined with a built-in processor, create an inertial sensor system fully cable of measuring the attitude of objects in 3D space.
The sensors in AHRS use algorithms to estimate this attitude in 3D space. Some AHRS units will use traditional Kalman filter algorithms that use magnetic and acceleration measurements to estimate the time-varying gyro bias in real-time. Other AHRS systems utilize modified non-Kalman filters that compute an estimation of orientation in real-time. A potential advantage of these modified algorithms is that they can outperform traditional Kalman filter-based sensors by providing real-time optimization of performance for varying magnetic or dynamic operating environments.
