Rockwell Collins AN PSN-13A GPS Navigation System

Rockwell Collins AN/PSN-13A Defense Advanced GPS Receiver (DAGR) is a rugged, handheld GPS navigation system designed for field use by the U.S. and allied military forces. It processes GPS signals with SAASM encryption for secure, anti-spoof navigation, and supports All-In-View navigation with up to 12 satellites to deliver reliable 3D positioning and timing data. The unit measures about 6.37 inches tall, 3.48 inches wide, and 1.6 inches deep, and is designed for handheld operation or hard-mount configurations to integrate with other equipment. The AN/PSN-13A carries NSN 5825-01-526-4783 and is an upgraded variant of the DAGR program (successor to the AN/PSN-11 PLGR), reflecting the transition to SAASM-based protection and modern cryptographic keys (SAASM 3.2). It outputs GPS-based navigation information to a variety of platforms, enabling downstream systems or operators to view position, velocity, and timing data as part of broader mission systems. The Rockwell Collins DAGR family has been used across the U.S. Department of Defense and select foreign military services, underscoring its role as a portable, resilient navigation solution in demanding environments.
