Magnetic heading sensors provide accurate directional information for helicopters, unmanned air vehicles, underwater vehicles and towed sensor systems.

·	The magetometer measures Earth’s magnetic field in three vectors (x, y & z)

·	It works in conjunction with other on-board sensing elements that measure the air frame vertical reference

·	The flight navigation / control computer combines this data and computes an accurate heading reference

·	This heading reference is needed to ensure that other sensors (cameras) / weapon system (laser guidance) are able to target accurately

·	Some UAVs rely on GPS only, but whilst GPS tells you where you are, it does not tell you what heading you are on

The AMR1 is a true strapdown magnetometer designed to provide high
precision vector measurement of the ambient magnetic field and is ideal for
use in Attitude and Heading Reference Systems (AHRS).
