11.3 AV-Mag External Magnetometer
11.3.1 Magnetometer Overview
AV-Mag external magnetometer (P/N UAV-1006321-001) is a 3-axis
electronic compass. It can precisely measure the earth’s magnetic field
and aid the AV-30 gyroscopic heading measurement, improving long-
term accuracy.
For the AV-Mag to be effective, the installation and calibration must be
done with accuracy and precision.
11.3.2 System Function
The AV-Mag, when paired with an AV-30, can provide consistent and
accurate heading. The AV-Mag is an aiding device and does not provide
full slaving to the AV-30.
