PM PNT Products in Development
Each PM PNT product under development has independent Milestone decisions based upon their acquisition phase. PM PNT development and fielding of each product line will employ an Evolutionary Acquisition approach, which allows for the acquisition of mature technologies and will deliver capabilities in increments based upon each product’s maturity and development schedules.
DAGR Distributed Device (D3)
The D3 addresses distributed PNT requirements, providing secure, real-time GPS data and precise time to an array of mounted client systems across all battlefield environments. The D3 allows up to eight client systems to simultaneiously receive positioning and timing data independently, providing a significant reduction in platofrm size, weight, power, and cost by eliminating the need for multiple GPS receivers on the platform.
Assured PNT (A-PNT)
A-PNT provides accurate and reliable PNT information while to Army Forces operating in various environments. The A-PNT Program is pursuing an integrated capability through four separate products: Dismounted A-PNT, Mounted-APNT, Pseudolites, and Anti-Jam Antenna Systems. Full capability is reached when employed together. The A-PNT Program focuses on platform distribution of PNT, scalable PNT architectures that pace the threat, and the ability to upgrade to future technologies, including Military-Code.
Described as “pseudo-salellites”, Pseudolites are terrestrially-based devices that transmit signals similar to GPS. Pseudolite transmitters deliver a high-power signal that is more difficult to manipulate or obstruct. The increased signal power improves a GPS receiver’s ability to acquire and track PNT information, providing a protected area for the Warfighter to operate. Pseudolites is intended to provide direct support to maneuver battalion operations, delivering scalable technology that is flexible to Warfighter needs.
Program Status: Pre-Milestone B
Dismounted Positioning, Navigation, and Timing
Dismounted Assured PNT includes the development and integration of multiple sensors for non-GPS augmentations. Receiver software can be upgraded to acquire Pseudolite signals to provide additional protection for military GPS in denied environments.
Program Status: Pre-Milestone B
Mounted Positioning, Navigation, and Timing
Product Status: Pre-Milestone B
Working in conjunction with the Mounted A-PNT system, the AJAS allows a PNT receiver continued access to the GPS signal even when operating in a challenged environment. AJAS will block signal interferance and provide true GPS data to the Mounted A-PNT system, which will then distribute that data to every client system on a platform.
Army System of Systems Solution Architecture
The SoSA is a set of future guidelines and standards for PNT systems that will guide and constrain the development of all Army systems consuming or providing PNT information with assurance. Once in existence, the Army SoSA will be used throughout system development, from concept to implementation and test, as well as during system modernization addition of PNT functionality. The Army SoSA will reach three goals, which will close current PNT capability gaps that Army forces face:
- Reduce PNT requirement inefficiencies/redundancies
- Decrease Warfighter vulnerabilities related to PNT
- Provide an affordable migration path to M-Code and future integrated PNT systems
SoSE&I is responsible for the development of the Army’s SoSA.
