The _____ provides azimuth and elevation data to the system

• A. Azimuth Determination Unit (ADU)
• B. Power Control Unit
• C. Target Acquisition Computer
• D. Elevation Measurement Unit

Answer: (A)

Providing accurate angular data to aim and guide the system is the key idea here. The unit responsible for that data is the Azimuth Determination Unit, because it supplies both the azimuth (horizontal angle) and the elevation (vertical angle) needed by the system to orient and track a target. This dual-angle feed ensures the fire control and launcher know exactly where to point.

The other components have different roles: the Power Control Unit handles electrical power for the launcher and subsystems, not angular data; the Target Acquisition Computer processes target information and may assist in detection or tracking but is not the direct source of the angular measurements sent to the system; and the Elevation Measurement Unit provides only the vertical angle, lacking the horizontal azimuth, so it cannot stand alone as the source for both angles.
