### Project ED5 — Assured Positioning, Navigation and Timing (PNT)

APNT Modernization develops prototypes for a layered/tiered PNT solutions for clients and vehicular platforms. APNT Modernization will fully implement a Modular Open Systems Approach (MOSA), support future integration of Military GPS User Equipment (MGUE) Increment 2, and improve complimentary PNT capabilities that provides a layered, accurate position and time in the absence of GPS for extended missions. This enables the Science & Technology transitions of incremental and complimentary technologies to fieldable Positioning, Navigation and Timing (PNT) solutions to pace or overmatch current and evolving threats and in accordance with National Defense Authorization Act (NDAA) Guidance (2021 NDAA: Section 1611). Fiscal Year (FY) 2027 Base funds in the amount of $18.993 million continues prototype hardware/software development, developmental testing, systems engineering, and program management for the APNT Modernization efforts.

## Mission & acquisition strategy

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 Military Code (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).

The APNT Modernization develops prototypes for a scalable/tiered PNT solutions for clients and vehicular platforms. APNT Modernization will fully implement a Modular Open Systems Approach (MOSA), support future integration of Military GPS User Equipment (MGUE) Increment 2, and improve complimentary PNT capabilities that provides a layered, accurate position and time in the absence of GPS for extended missions. The acquisition strategy for the APNT Modernization effort employs a dual-vendor approach for its prototyping phase. This initiative leverages a competitively awarded Other Transaction Authority (OTA) agreement to foster robust competition.
