Assured Positioning, Navigation and Timing (PNT)

Mission — MOUNTED source

There are no Base funds for project Mounted (EJ2) in Fiscal Year (FY) 2026. The Mounted Assured Positioning, Navigation and Timing System (MAPS) meets congressional (10 USC 2281) and Department of Defense guidance to provide resilient and survivable, M-Code Global Positioning System (GPS) capable Ground User Equipment (MGUE) receivers and Alternative Navigation (ALTNAV). The MAPS delivers systems that provide the Army's combat forces access to assured PNT information under conditions where space-based GPS may be limited or denied, enabling Army forces the ability to move, shoot, communicate, and provide situational awareness. MAPS addresses two critical capability gaps: Access and Integrity. Access is the ability to retrieve PNT information in a contested Electronic Warfare/Cyber environment. Integrity is the ability to trust the PNT information. PNT is a critical enabler of many Army Maneuver, Fire and Command and Control systems that are dependent on accurate Position and Timing. The MAPS will provide PNT when GPS is degraded or denied through military code (M-Code) GPS, Alternative Navigation (ALTNAV) signals, timing, sensor fusion, anti-jam antenna, and beam steering. This capability will deliver distributed assured PNT capabilities to Armored, Stryker and Infantry Brigade Combat Team (BCT) platforms in an iterative and affordable manner that allows for future modernization. - MAPS GEN II completed Milestone C in July 2022. - MAPS GEN II completed Initial Operational Test & Evaluation (IOT&E) in February 2024 and Full Rate Production authorized March 2025.

Mission — DISMOUNTED source

There are no Base funds for project Dismounted (EH8) in Fiscal Year (FY) 2026. Dismounted Assured PNT (APNT) System (DAPS) meets congressional (10 USC 2281) and Department of Defense guidance to provide resilient, survivable, M-Code Global Positioning System (GPS) capable Ground User Equipment (MGUE) receivers and Alternative Navigation (ALTNAV). The DAPS will provide Soldiers Assured PNT (APNT) information utilizing various sources of PNT data to address multiple threats and ensure mission success where Global Positioning System (GPS) may be limited or denied. DAPS will deliver APNT in an optimized form factor that supports dismounted mission profiles in denied environments. - DAPS GEN II is leveraging the QRC and lessons learned. Initial Operational Capability completed 07 February 2025.

Mission — Assured Positioning, Navigation and Timing (PNT) source

This funding line is directly aligned to the Army Assured Positioning, Navigation and Timing modernization priority. The Assured Positioning, Navigation and Timing (APNT) capability provides Army ground maneuver forces access to M-Code and assured PNT in accordance with National Defense Authorization Act guidance under conditions where Global Positioning Systems (GPS) may be limited or denied (jammed and spoofed). APNT products are ruggedized tactical systems that enable Army forces the ability to shoot, move, communicate, thereby allowing forces to maneuver from operational and strategic distances to close with, destroy, and exploit the enemy with sufficient combat power, tempo, and momentum. APNT addresses two critical capability gaps: Access and Integrity. Access is the ability to retrieve accurate PNT information in a contested Electronic Warfare/Cyber environment. Integrity is the ability to trust the PNT information. PNT is a critical enabler of many Army Maneuver, Fires, Intelligence, Mission Command and communications that are dependent on accurate Position and Timing, and a foundational Multi-Domain Battle capability to support: calibrated force posture (position and maneuver across strategic distances); multi-domain formations (operate in contested spaces against near-peer adversaries); convergence (continuous integration of capabilities in all domains). APNT capabilities provide critical support to the execution of the Army's Deliberate Transformation as well as Transformation in Contact and the Next Generation Command and Control (NGC2) environment. Approved Requirements: The Army Requirements Oversight Council (AROC) approved the Alternative Navigation (ALTNAV) Abbreviated Capabilities Development Document (A-CDD) in 29 August 2022. The Joint Requirements Oversight Council (JROC) approved the Dismounted APNT System (DAPS) Capabilities Development Document (CDD) on 28 January 2022. The Army Requirements Oversight Council (AROC) approved the Mounted APNT System (MAPS) CDD on 12 September 2020. MAPS and DAPS are implementing Congressional and OSD guidance to develop and field Military Code (M-Code) Global Positioning System (GPS) Ground user Equipment. The AROC approved the Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance (C5ISR) Modular Open Suite of Standards (CMOSS) Mounted Form Factor (CMFF) Abbreviated Capabilities Development Document (A-CDD) on 04 January 2021. In support of House Report 116-442, 2020, the program will prototype modular cards and software according to the Modular Open System Approach (MOSA) standards, for future modernization and new weapons systems. Joint Requirements Oversight Council Memo (JROCM) 049-10, dated 05 April 2010, approved the PNT Assurance Initial Capabilities Document and designated the Army as the Lead Component for Assured PNT. (BV4) - PE 0604120/BV4 has no Base funds requested in FY 2026. The Area Protection and Alternative Navigation project line funded the Alternative Navigation (ALTNAV) Ground Control Segment (GCS) development effort. The ALTNAV GCS is a global navigation solution providing warfighters with an alternative source of positioning and timing information. In accordance with National Defense Authorization Act (NDAA) Guidance (2021 NDAA: Section 1611), ALTNAV GCS is a complementary capability to Global Positioning System. ALTNAV GCS may be used as contingency in the PNT PACE (Primary, Alternative, Contingency, Emergency) Plan that facilitates continued operations as GPS is degraded or denied. ALTNAV GCS effort formally became a Middle Tier of Acquisition - Rapid Fielding (MTA-RF) program in FY24. The total cost of the ALTNAV Middle Tier of Acquisition effort is $106.1M procurement from FY24-FY27 and is a single global alternative PNT system. The $106.1M ALTNAV requirement is fully funded across the Future Years Defense Program. (ED5) - The Assured Positioning Navigation Timing project develops APNT Modernization prototypes that will develop the next generation of PNT solutions for clients and vehicular platforms. It will fully implement a Modular Open Systems Approach (MOSA), incorporate Military GPS User Equipment (MGUE) Increment 2, and improve complimentary PNT capability that provides accurate positioning and timing in the absence of GPS for extended missions. The Assured Positioning Navigation Timing is also developing developed a Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance (C5ISR) Modular Open Suite of Standards (CMOSS) Mounted Form Factor (CMFF) APNT Card. These two efforts will enable the transition of incremental and disruptive technologies to fieldable PNT solutions to pace or overmatch current and evolving threats in accordance with National Defense Authorization Act (NDAA) Guidance (2021 NDAA: Section 1611). Starting in FY 2026 the CMFF APNT Card effort was realigned ($5.365M) to Budget Activity-5 (BA-5) DL9 Project Code APNT Cards C5ISR Mounted Form Factor (CMFF) within PE 0604805A Command, Control, Communications Systems - Eng Dev.
