Assured Positioning, Navigation and Timing (PNT)
Abstract
Assured Positioning, Navigation and Timing will provide Army forces with unhindered access to trusted Positioning, Navigation, and Timing (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 which can be impacted by current and emerging threats and field conditions, which means that PNT access and integrity to the Warfighter cannot be 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: (1) 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. (2) 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. (3) 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 wirelessly on the soldier; (4) The Anti-Jam 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 has transitioned into four (4) separate project lines for each Assured PNT subprogram. EH8 – Dismounted subprogram. EH9 – Pseudolites subprogram. EJ2 – Mounted subprogram. EJ3 Anti-jam Antenna subprogram. FY 2016 Base funds in the amount of $30.058 million are provided to continue the development of the Pseudolite sub-program; program planning and technical evaluation of the Assured PNT sub-system and architecture development; integration of M-Code in accordance with Public Law 111-383 Sec 913; participation in various Navigation Warfare (NAVWAR) test events and support to the Military GPS User Equipment (MGUE) Precision Guided Munitions. The details of this program are reported in accordance with Title 10, United States Code, Section 119(a)(1).
