How many points can be set in the AN/PSN-11 (GPS)?

The AN/PSN-11, also known as the Precision Lightweight GPS Receiver (PLGR), is designed to provide accurate positioning and navigation capabilities. One of its key features includes the ability to store multiple waypoint points, which are critical for military operations and navigation tasks.

The correct answer is that the AN/PSN-11 can store 999 points. This increases operational flexibility by enabling users to input a vast number of waypoints for different locations, ensuring that the system can be employed effectively in various mission scenarios. Storing this many points allows users to access previously designated locations without re-entering data, thus enhancing efficiency during missions.

While the other options suggest different capacities, none align with the specified capability of the AN/PSN-11. For example, while capacity limits may differ across various GPS models, the established maximum for the AN/PSN-11 is confirmed to be 999 points, making it essential for air defense operations where precise and quick location data is paramount.
