Defense Advanced GPS Receiver
DAGR is a 12-channel receiver intended primarily for handheld use that provides real-time position, velocity, navigation, and timing information. It includes a graphical user interface that greatly enhances a Soldier’s situational awareness, effectiveness, and safety. It was procured as the next generation replacement for the aging PLGR, and provides more secure and accurate service in a much smaller and less power-hungry package. It can be mounted into platforms or integrated into other systems to provide PNT service.
The DAGR uses state-of-the-art GPS receiver technology including “All in View” satellite tracking for better accuracy, and the Selective Availability Anti-Spoof Module (SAASM) for improved security.
The USAF Positioning, Navigation, and Timing – Program Office (PNT-PO) located at Robins AFB, GA, manages the overall program and contract as the Primary Inventory Control Authority (PICA) for DAGR. Army CECOM-ILSC manages the DAGR inventory and maintains oversight. Army PM-PNT retains “Materiel Developer (MATDEV)” and “Life Cycle Management” responsibilities.

120,000 fielded 2004-2015; still in production
The GB-GRAM is an open architecture specification that defines non-proprietary functional, performance, and interface requirements for a family of secure embeddable GPS receivers. GB-GRAM embedded GPS receivers are capable of processing the Precise Positioning Service (PPS) signal to provide highly accurate, real-time, PNT information 24-hours a day under all weather conditions.
The GB-GRAM specification (MIL-PRF-GB-GRAM-300) defines requirements that target the ground domain. The current production version of GB-GRAM is provided in the Small Serial Interface (SSI) form factor. This product, delivered under the GB-GRAM contract, is the Miniature Precision Lightweight GPS Receiver (PLGR) Engine- Selective-Availability Anti-Spoofing Module (SAASM) (MPE-S). The MPE-S is an embeddable lightweight “All in View,” dual-frequency, continuously tracking GPS receiver that uses the SAASM to access the PPS signal. The functions and capabilities of the SSI-GB-GRAM are tailored to suit the operational requirements of ground-based platforms with low-dynamic characteristics including mounted and dismounted land users and waterborne vehicles. SSI-GB-GRAM can be integrated into a wide variety of command, control, communications, and computer systems to host system functions including position location, target location, time synchronization, rendezvous, and en-route and terminal navigation.

PLGR
PLGR
The Precision Lightweight GPS Receiver (PLGR) is obsolete and can no longer be repaired or supported. The last software update was released in FY2005, which included the 2005-2010 World Magnetic Model (WMM) update. PLGRs have been replaced with the next generation handheld Receiver, the AN/PSN-13(A) Defense Advanced GPS Receiver (DAGR).
Unless you have an identified exception by the PM, it is past time to turn in any AN/PSN-11 or AN/PSN-11(V)1 PLGRs (NSNs: 5825-01-374-6643 and 5825-01-395-3513) remaining on your unit's property books.
