14 GMU 11 (MAGNETOMETER) INSTALLATION
This section contains general information as well as installation information for the GMU 11. Use this
section to mount the GMU 11 unit.

14.1 Equipment Description

The Garmin GMU 11 Magnetometer is a remote mounted device that interfaces with a Garmin ADAHRS
(GSU 25) to provide flight attitude and heading data for flight instrumentation.
An Attitude and Heading Reference System combines the functions of a Vertical Gyro and a Directional
Gyro to provide measurement of Roll, Pitch, and Heading angles. The Garmin ADAHRS and
magnetometer replace traditional rotating mass instruments.
Using long-life solid-state sensing technology, the GMU 11 Magnetometer uses magnetic field
measurements to create an electronically stabilized AHRS.
The GMU 11 magnetometer provides magnetic information to support the function of the ADAHRS
(GSU 25). The supply voltage for the GMU 11 Magnetometer comes from aircraft power (9-32 V
100mA.)
NOTE
The GSU 73 is not compatible with the GMU 11 magnetometer. Installations that include
a GSU 73 must also include a GMU 22 connected to the GSU 73.
