No in-field calibration required

Low SWaP AHRS Targeting Module

Introducing Headway, a breakthrough Low SWaP AHRS targeting module that delivers in-field, accurate heading to 1º, without any need for in-field manual calibration.


Unlike other Attitude Heading Reference Systems (AHRS) that require in-field, time-consuming recalibration, the Headway targeting module constantly delivers heading data in static and dynamic situations, with 1º of accuracy. And because it contains the latest IMU Sensors and PNI´s RM3100 magnetic sensor integrated with sensor fusion Edge AI algorithms, Headway needs no manual calibration.


Headway is an ultra-compact IMU, uses ultra low power, and is shock and temperature fluctuation resistant.


Headway is easy to integrate and is ideal for use in targeting, drones, unmanned vehicles, augmented reality, and virtual reality headsets.
