Assured Positioning, Navigation and Timing (PNT)
Abstract
Assured Positioning, Navigation and Timing (PNT) will provide Army forces with unhindered 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 April 5th 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 July 30th 2013. The Assured PNT draft Capabilities Development Document was validated by the Army Requirements Oversight Council (AROC) on July 28th 2014. PNT is a critical enabler of many Army systems. The current capability, GPS, is a fixed frequency system vulnerable to current and emerging threats and field conditions, 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 family of solutions which includes four subprograms: (EH9) The Pseudolites subprogram provides 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 PNT subprogram is the integration of multiple sensors and provides PNT platform distribution. The Mounted PNT subprogram incorporates a System of Systems architecture that acquires, protects and distributes secure PNT on stationary and vehicular platforms. (EH8) The Dismounted PNT subprogram is the integration of multiple sensors for platform distribution of PNT on the Soldier. The Dismounted PNT subprogram incorporates a System of Systems architecture that acquires, protects and distributes secure PNT on the soldier. (EJ3) The Anti-Jam Antenna subprogram provides GPS signal protection and PNT Assurance in challenged environments through anti-jam technologies. Anti-jam enables tactical capabilities through assured signal acquisition in challenged environments. 0604120/ED5 funding line continues as the Assured PNT parent funding line. However, four (4) separate project lines were created for the Assured PNT subprograms; EH8 – Dismounted PNT subprogram; EH9 – Pseudolite subprogram; EJ2 – Mounted PNT subprogram; EJ3 - Anti-Jam Antenna subprogram. FY 2017 Base funds in the total amount of $83.279 million are provided to continue the development of the A-PNT program. The ED5 funding line accounts for $11.116 million for PNT System of Systems Architecture (SOSA) Testing and enhancements of Army PNT capabilities against emerging threats. The EH8 funding line accounts for $3.200 million for risk reduction activities and program documentation in preparation for Milestone B of the Dismounted PNT subprogram. The EH9 funding line accounts for $57.411 million for the continuation of the TMRR competitive prototyping effort and program documentation in preparation for Milestone B for the Pseudolite subprogram. The EJ2 funding line accounts for $11.552 million for Technology Maturation and Risk Reduction (TMRR) and program documentation in preparation for Milestone B of the Mounted PNT subprogram. The details of this program are reported in accordance with Title 10, United States Code, Section 119(a)(1).
