The azimuth and elevation data is provided by which unit?

• A. Missile Umbilical Junction (MUJB)
• B. Guidance Computer
• C. Azimuth Determination Unit (ADU)
• D. Missile Interface Module

Answer: (C)

Firing data uses a dedicated angular measurement unit that specializes in determining where the launcher is pointing. The Azimuth Determination Unit calculates the horizontal (azimuth) and vertical (elevation) angles to the incoming threat and provides those precise angles to the Guidance Computer. This separation keeps angle determination separate from power, interface, and processing roles handled by other subsystems. The Missile Umbilical Junction focuses on power and data links, the Guidance Computer performs the calculations and control once it has the angles, and the Missile Interface Module handles signals to the missile. So, the unit that specifically supplies the azimuth and elevation data is the Azimuth Determination Unit.
