What does PADS stand for?

• A. Position attitude determination system
• B. Position attitude direction system
• C. Position attitude determination subsystem
• D. Platform orientation data system

Answer: (C)

The mechanism being discussed is about providing the launch platform with its exact location and how it’s oriented in space, so the system can aim and guide the missile accurately. Position covers where you are, while attitude covers how you’re tilted (pitch, yaw, roll). Determination is the process of calculating those values from sensors like an inertial unit and possibly GPS. Subsystem signals that this is one component of the larger fire-control/navigation suite, not the entire system itself, which is why this wording fits best. The other options either change the scope (system rather than subsystem), or drop either position or attitude, or describe something only about orientation or data rather than both position and attitude together.
