Description:
The NAVSTAR Global Positioning System (GPS) satisfies validated joint service requirements for worldwide, accurate, common grid,
three-dimensional positioning/navigation for military aircraft, ships, ground vehicles and ground personnel. The system is comprised of three
segments: (1) satellites, (2) a control network and (3) user equipment (UE). The satellites broadcast high accuracy data using precisely
synchronized signals that are received and processed by UE installed in military platforms. The control network updates the navigation
messages broadcast from the satellites to provide system vectors to target location or navigational way points. Air Force UE consists of
5-channel handheld sets, Precision Lightweight GPS Receiver (funded in Other Procurement, Air Force appropriation), and 5-channel airborne
sets (funded in Aircraft Procurement appropriation).
1. PRECISION LIGHTWEIGHT GPS RECEIVER (PLGR): The PLGR is a lightweight, handheld GPS set that receives satellite signals and
processes the data into precise position and velocity information for low dynamic motion users. This non-developmental item supports Air
Liaison Officers (ALOs), Forward Air Controllers (FACs), Explosive Ordnance Disposal Teams, Security Police and Combat Control Teams
(CCTs) by supplying precise position information on a universal grid reference system and time synchronization for anti-jam communications
systems. The Air Force has lead service responsibility for PLGR procurement. FY01-03 funding will extend the PLGR warranties.
2. KEY DATA LOADING INSTALLATION FACILITY (KLIF)/GPS SECURITY DEVICE: FY01-03 funding provides for programming of
black key algorithms into Selective Availability Anti-Spoofing Module (SAASM) chips, providing an accurate positioning solution for GPS
users using secure equipment.
3. DEFENSE ADVANCED GPS RECEIVER (DAGR): DAGR, the follow-on to the PLGR, will be a handheld self-contained GPS receiver
with precise positioning using SAASM. It will be interoperable with the PLGR existing interfaces and support equipment so that present
integration and support capabilities are minimally affected. DAGR will be primarily used in the stand alone mode, in wheeled and tracked
