The Start Position input is latitude and longitude of the receiver antenna. Which option best describes this concept?

• A. The Receiver Antenna
• B. The Ship's Motion
• C. The Target's Location
• D. The Observation Deck

Answer: (A)

The Start Position input is the fixed coordinates of the receiver antenna—the instrument’s own location at the start of measurements. Those latitude and longitude values set the reference point for processing, allowing you to determine how things move relative to the receiver and to establish baselines. The ship’s motion would be represented by later position updates, not the initial coordinate itself. The target’s location is what you’re ultimately solving for, not the starting point of the receiver. The observation deck is simply a platform name, not the reference coordinate. So the best description is the Receiver Antenna.
