Competitive 9 DOF Aviation Sensor Rugged Compact Ahrs Attitude Heading Reference System for Unmanned Aircraft AHRS3000

Product Description

AHRS3000 Attitude and Heading Reference System (AHRS) is a high performance inertial measurement system, it adopts digital signal processor to realize temperature calibration and non orthogonal error. No matter the carrier is moving or static, AHRS3000 can work stably and provide highly precise 3 attitude angles (yaw, pitch, roll) and other assistant sensor signals (acceleration, angular rate, magnetic field intensity and temperature) at any time.

AHRS3000 uses a microprocessor to integrate angular rate sensor data and provides a closed loop system of error correction to adjust

biases from earth rotation and from instrument offsets. Interface to the microprocessor is done through a 16-bit A/D and a 12-bit D/A converter. The solid state vibrating structure angular rate gyros used in this system provide extremely high reliability, low power consumption, shock resistance and low cost.

How does Attitude and Heading Reference System Works?

Attitude and heading reference systems (AHRS) have been providing heading and attitude information with greater accuracy and reliability than traditional mechanical gyros for years now. But how do these solid-state systems deliver this information, and how do they do so using increasingly smaller and lighter equipment?

Micro Electronics

An AHRS’s key features include ­micro-electronic mechanical gyros, ­accelerometers and a magnetometer or flux valve. The micro-electronic mechanical gyros are responsible for capturing motion data as an aircraft moves about all three axes. They do this by ­using vibrating components. As an aircraft changes direction, these vibrations deviate, and these deviations can be measured and used to calculate directional change data.

Gyro Drift

In order to account for gyro drift, which can produce erroneous data, an AHRS must also rely on accelerometers as well as a magnetometer or flux valve. The former uses gravity to serve as both an initial attitude reference as well as an inflight reference, whereas the latter uses Earth’s magnetic field to provide heading information.

The AHRS aggregates all the information from these different components and conducts complex algorithms and calculations to provide highly reliable attitude and heading data.
