Assured Positioning, Navigation and Timing (PNT)
Abstract
Mission Command Network Modernization Implementation Plan - Line of Effort 1, 17 Apr 2018. Assured Positioning, Navigation and Timing (A-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. The Assured PNT Cross Functional Team is drafting individual requirements for each product. The Mounted A-PNT System (MAPS) Directed Requirement was approved 13 Jan 2019. Positioning, Navigation and Timing (PNT) is a critical enabler of many Army systems. The current Global Positioning System (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 to and integrity of the PNT signal is not guaranteed. This situation degrades mission performance to an unacceptable level. Therefore, current Army systems cannot operate in an electronically contested or degraded environment at the required PNT Assurance Levels with GPS alone. A-PNT consists of five projects; (FJ8) Assured PNT, (FJ9) Dismounted A-PNT System (DAPS), (FK1) Pseudolite, (FK2) Mounted A-PNT System (MAPS), and (FK3) Anti-Jam Antenna System (AJAS). These A-PNT projects support access to and integrity of PNT information. Project Manager (PM) PNT manages these five project (Assured PNT, DAPS, Pseudolite, MAPS, and AJAS) constructed to investigate, prototype, experiment, model, asses, develop, test, modify, field, and sustain A-PNT solutions. Assured Positioning, Navigation and Timing (A-PNT) consists of: (FJ8) - The Assured PNT project funding line is for: PNT System of Systems Architecture (SOSA) Testing to validate performance of end-to-end system performance; Resiliency and Software Assurance Measures (RSAM) upgrades to legacy GPS systems. In addition, this line supports the development of complementary and adjacent A-PNT technologies as well as Enterprise Enablers including the Alternative Navigation (ALT NAV) signal Enterprise Build-out. These technologies will be integrated into future products, strategies, concepts of operation, architectures, and platforms to assure PNT. (FJ9) - The Dismounted A-PNT System (DAPS) provides assured PNT data to Soldier borne equipment (e.g. Nett Warrior, and other Soldier architecture compliant systems). DAPS is a Size, Weight, and Power, optimized military GPS, fused with other sensors. (FK1) - The Pseudolite project was terminated by the Army on 12 Feb 2019 after the Fiscal Year 2020 submission lock. Therefore, the Army will realign FK1 funding within the existing PE 1206120A. The requirements addressed by the Pseudolite solution are still valid capability gaps. Pseudolite funding and activities will pivot to support the broader mission of Alternative PNT & Area Protection to mitigate threats in Multi-Domain Operations (MDO). For FY21 a new project line will be established to transition the effort of Alternative PNT & Area Protection. These technologies provide agile and adaptive mechanisms for integrating sensors, signals and software to provide Radio Frequency (RF) and non-RF threat mitigation. (FK2) - The Mounted A-PNT System (MAPS) provides assured PNT data under conditions where space-based PNT (e.g. GPS) may be limited or denied by fusing non-RF sensors with GPS. It distributes assured PNT data to tactical command, communication and control systems on Army tactical and combat vehicles. (FK3) - The Anti-Jam Antenna System (AJAS) provides protection against jamming threats. The AJAS is tightly coupled with the MAPS to provide GPS signal protection and assured PNT in challenged environments on Army tactical and combat vehicles. FY 2020 Base funds in the total amount of $192.562 million are provided to continue the development of the Assured PNT program. The FJ8 funding line accounts for $42.379 million for PNT System of Systems Architecture (SOSA) Testing, Resiliency and Software Assurance Modification (RSAM), ALT NAV Enterprise Build-out and continued development of Assured PNT Enterprise Enablers. The FJ9 funding line accounts for $32.360 million to continue prototype development and testing for the DAPS. The FK1 funding line accounts for $42.452 million to continue to fulfill the assured PNT information gap by pivoting to Alternative PNT & Area Protection, accelerating the Mounted A-PNT System (MAPS), and aligning to Army Modernization priorities. As a result, this funding will be realigned to FJ8 ($18.139 million) and FK2 ($24.313) million. The FK2 funding line accounts for $66.471 million to continue integration, training and Soldier assessment of MAPS on selected combat vehicles and command, control and communication systems. The FK3 funding line accounts for $8.900 million to continue integration, training and Soldier Assessment of AJAS, fielded with MAPS on selected combat vehicles and command, control, and communication systems.
