Figure 4-3. GSU 73 Orientation Calibration
The GSU 73 includes an extremely sensitive strap-down inertial measurement unit. It must be mounted
rigidly to the aircraft primary structure, preferably to a metallic structure to conduct heat away from the
unit. Do not mount the GSU 73 in an enclosed area, it should be mounted in a location that provides
adequate airflow to comply with the maximum outer case temperature listed in Section 4.3.
