Compass Terminology 101

There is so much terminology when talking about navigation products that it can be confusing. What is an Attitude Heading Reference System (AHRS) and how does it differ from an Inertial Navigation Systems (INS)? Some products have GPS integrated and others don’t.  Welcome to Compass Terminology 101. Let’s go over the basics of these terms […]

Adaptive Calibration Technology in Digital Compasses and Inertial Systems

Summary: Conventional digital magnetic compasses require a complex and cumbersome “in-field” calibration process. This calibration, commonly referred to as the “Kabuki Dance”, is not embraced by most users including the military and is often performed improperly, incompletely, or sometimes not at all. This results in diminished sensor performance and poor overall accuracy, in targeting and […]

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 […]
