(U) Provides real time precise position, velocity and time capabilities to enhance platform/ground soldiers navigation, site surveying, field artillery placement, target acquisition, target handoff operations, and communications systems timing. Improve lethality based on precise knowledge of the location of friendly firepower, coupled with precision forward-observer determinations of enemy locations and movements. In non-combat operations, it will support efficient off-road navigation for supply distribution, vehicle recovery, rendezvous, and reconnaissance. Defense Acquisition GPS Receivers (DAGR) are scheduled as a follow-on to the PLGR, and 210,000 are expected to be in procurement by year 2000.
User Impact (U):
(U) The Primary Operational mission of the DAGR is to provide precise positioning service (PPS) support, position, velocity, navigation and timing (PVNT) to all missions that involve land-based war-fighting operations. In addition, DAGR will provide an operational response to GPS Baseline 2000. This, combined with changes in the battlefield operational environment, has created a mission need for an enhanced GPS capability that provides greater integrity, accuracy and survivability. These operations include DAGR supported ground personnel, indirect fire weapon systems, and armored vehicles. DAGR can also be used as a secondary or supplemental aide to aviation-based missions that involve operations in low-dynamic fixed-wing aircraft and helicopters. Additionally, the DAGR may be used as an aide to navigation in water-borne operations; such as for combat swimmers, submarines and watercraft. The mission places the user in an increasingly unfriendly electromagnetic warfare environment. The US Space Command MNS (MNS 003-95) approved by the JROC in Mar 96 describes the need "to protect our ability to receive the GPS navigation signals" as well as the PLGR functions already enjoyed by users. This requires that the DAGR be as capable as the PLGR, with additional features that provide the means to operate in a more challenging electromagnetic warfare environment.
(U) The DAGR will provide improved PPS support to a variety of land, sea and airborne users. The DAGR will be backward compatible with the PLGR, and will provide position, velocity, navigation and time (PVNT) information derived from the GPS satellite constellation. It will communicate these resulting data via a graphical user interface and by various electronic interfaces (self-contained or remote). The data generated will include user location in various map formats, point to point navigation, and timing signals for other user equipment. In order to provide these capabilities while operating in an increasingly hostile electronic environment, the DAGR must be capable of secure, anti-jam, anti-spoofing operation. It will be used in stand alone or external integrated configurations. See Section 5.5 of this SAMP for a more detailed product description.
