Which technology helps identify the locations of officers and patrol cars?

• A. Global Positioning System (GPS)
• B. Radar
• C. Cellular triangulation
• D. Computer-aided dispatch

Answer: (A)

The idea being tested is real-time location tracking of patrol units. Global Positioning System provides precise geographic coordinates for a device or vehicle, allowing dispatchers and supervisors to see exactly where an officer or patrol car is on a map, watch movements, and coordinate responses. GPS works by receiving signals from satellites and computing latitude, longitude, and sometimes altitude; modern patrol vehicles have GPS receivers that feed this data into mapping software and the dispatch system, giving clear, up-to-the-second location information. This direct measurement of where units are makes it the best fit for identifying locations.

Radar, on the other hand, measures the speed of moving objects rather than the exact position of units. Cellular triangulation can estimate location by using signal timing from nearby towers, but it’s generally less precise and not the standard for actively tracking police units in real time. Computer-aided dispatch is the system that manages calls and resources and displays unit locations, but the actual location data it shows comes from the positioning technology, with GPS being the primary method used.
