AHRS-M1

The AHRS-M1 is the first micro-sized, light weight, low power Attitude Heading Reference System (AHRS) product with a revolutionary built-in adaptive-calibration mode. It utilizes a proprietary calibration algorithm that provides continuous, adaptive calibration without the need to perform a traditional and complex “12-point” calibration. Instead, the AHRS-M1 learns on the fly, using the natural motion of the application platform to continuously calibrate the platform’s magnetic properties – eliminating hard and soft iron distortions. Ideal for SWaP-C improvements, the system weighs 6.7 grams in a very small form factor. Leveraging market-leading, on-board tri-axial magnetometers and MEMS accelerometers and gyroscopes, the AHRS-M1 delivers temperature compensation, lower heading drift, and superior system performance even in the presence of platform vibration. Sparton’s proprietary state-of-the-art AdaptNavTM sensor fusion algorithms allow the system to provide accurate attitude and heading outputs, including full 360° tilt compensation even when subject to highly dynamic operating environments and transient magnetic interference. The AHRS-M1 also includes Sparton’s NorthTekTM on-board programming environment, making it the world’s only micro-sized, programmable, and configurable AHRS – providing users virtually limitless product customization and integration flexibility.
