Assured Positioning, Navigation and Timing (PNT)
Abstract
Assured Positioning, Navigation and Timing (PNT) will provide the Army's ground maneuver forces access to trusted PNT information under conditions where space-based PNT Global Positioning System (GPS) may be limited or denied. Joint Requirements Oversight Council Memo (JROCM) 049-10, dated 05 Apr 2010, approved the Positioning, Navigation and Timing Assurance Initial Capabilities Document and designated the Army as the Lead Component for Assured PNT. The Material Development Decision (MDD) was approved on 30 Jul 2013. The Assured PNT draft Capabilities Development Document was validated by the Army Requirements Oversight Council (AROC) on 28 Jul 2014. PNT is a critical enabler of many Army systems. The current GPS capability is a fixed frequency system vulnerable to current and emerging threats, and field conditions (e.g. urban, dense vegetation), which means Warfighter assured access and integrity to PNT is not guaranteed. This situation degrades mission performance to an unacceptable level. Therefore, current Army systems cannot operate at the required PNT Assurance Levels with GPS alone. Assured PNT is a system of systems consisting of one project (ED5) Assured PNT and four separate and interdependent PNT products; (EH8) Dismounted A-PNT System, (EH9) Pseudolite, (EJ2) Mounted A-PNT System, and (EJ3) Anti-Jam Antenna System (AJAS). These interdependent PNT products assure access to and integrity of PNT information. Each product provides a degree of standalone capability that can be leveraged across the solutions and enterprise enablers to raise the capabilities in all environments and across all formations and warfighting functions. Program Manager (PM) PNT manages these four products (Dismounted A-PNT System, Pseudolite, Mounted A-PNT System, and AJAS) constructed to develop, test, field, and sustain the A-PNT materiel solution. The overall mission of PM PNT also includes experimentation and demonstration activities aligned with the Secretary of the Army and Chief Staff of the Army modernizations areas. The final acquisition and contracting strategy are under development. Assured PNT consists of: (ED5) - The Assured PNT funding line originally represented the entire program prior to breaking into four separate funding lines. The FY17-FY22 funding is for PNT System of Systems Architecture (SOSA) Testing and Resiliency and Software Assurance Modification (RSAM) to legacy GPS systems. (EH8) - The Dismounted Assured Positioning, Navigation and Timing (PNT) System is a Size, Weight, Power, and Cost (SWAP-C) optimized military Global Positioning System (GPS) and non-GPS sensor suite that acquires and distributes trusted PNT data to soldier-borne systems. (EH9) - The Pseudolite system provides area protection and PNT Assurance in GPS denied environments by providing terrestrial radio navigation (GPS-like) service in electronically or physically challenged environments using a higher power signal. (EJ2) - The Mounted Assured PNT System fuses military GPS with physics based sensors and timing technology to acquire and distribute secure trusted PNT data to tactical client systems on vehicular and watercraft platforms. (EJ3) - The Anti-Jam Antenna Systems (AJAS) provides GPS signal point protection and PNT Assurance in challenged environments through anti-jam technologies. AJAS enables tactical capabilities through assured signal acquisition in challenged environments. There are no FY 2019 Base funds. Program Element (PE) 0604120A transitions to PE 1206120A beginning in FY19.

- Change Summary Explanation
- FY 2017 reduction of $.205 million reflects FFRDC and SBIR/STTR Transfer. RDT&E funding decreased from $164.967 million in FY2018 to $0.0 million in FY2019. In accordance with Section 239 of Title 10, U.S.C., the FY 2018 President's Budget established new Program Elements (PE) to account for all of the Department's Space Major Force Program (MFP)-12 programs. To comply with this requirement, PE 0604120A transitions to PE 1206120A beginning in FY19. Program Element (PE) 0604120A project ED5 transitions to PE 1206120A project FJ8 beginning in FY19. Program Element (PE) 0604120A project EH8 transitions to PE 1206120A project FJ9 beginning in FY19. Program Element (PE) 0604120A project EH9 transitions to PE 1206120A project FK1 beginning in FY19. Program Element (PE) 0604120A project EJ2 transitions to PE 1206120A project FK2 beginning in FY19. Program Element (PE) 0604120A project EJ3 transitions to PE 1206120A project FK3 beginning in FY19.
