The AN/MPN-14K Mobile Ground Approach System can be configured as a complete Radar Approach Control (RAPCON) or Ground Controlled Approach (GCA) facility. The radar unit is used by air traffic controllers to identify, sequence, and separate participating aircraft, provide final approach guidance through air defense corridors and zones, and coordinate ID and intent with local air defense units at assigned airports and air bases. These services can be provided in all types of weather.
