Aviation ASSURED PNT

Aviation ASSURED PNT is an Army aircraft-modification line intended to give aircrews dependable position, navigation, and timing (PNT) information when satellite navigation is contested. It is funded under Aircraft Procurement, Army, Budget Activity 02, Modification of Aircraft, and Budget Subactivity 10. The effort targets near-term improvements to the enduring aviation fleet so crews can perform PNT-dependent tasks, complete missions, or recover safely when their primary navigation source is degraded. Its layered approach combines modernized Global Positioning System (GPS) receivers, more resilient navigation equipment, and anti-jam antennas.

The modification applies across listed UH/HH/MH-60, CH/MH-47, and AH-64 variants, as well as fixed-wing aircraft and unmanned aircraft systems. The Army also plans to evaluate alternate PNT (ALT-PNT) sources that do not depend on GPS, either as standalone functions or blended with existing navigation. The resulting architecture is intended to accept position, velocity, and time measurements from other PNT solutions. Because the line buys several distinct modification items, it does not have a single Army Acquisition Objective; planned resources are distributed among the Army, Army National Guard, and Army Reserve.

DGNS (AN/ASN-128D) CDU/SW Upgrade ECP B-Kit is the Doppler Global Positioning System Navigation Set upgrade identified as the first modification item. Its system-engineering purpose is to reduce space, weight, and power demands while supporting current and future civil-airspace requirements. The acquisition record identifies B-kit fielding, shared services, and system test and evaluation in prior-year funding, with BAE International Incorporated of Wayne, New Jersey, listed as manufacturer. Unlike the two other modification items, the financial plan shows no additional DGNS procurement in fiscal year 2027.

MAGNA GPS Anti Jam Antenna supplies an adaptive antenna system that receives legacy and modernized GPS satellite signals. By rejecting interfering signals before they reach the GPS receiver, the Multi-platform Anti-jam GPS Navigation Antenna (MAGNA) helps preserve access to GPS-derived PNT in a jammed or degraded environment. Fiscal year 2027 supports procurement of platform-specific A-kits and B-kits, spares, system evaluation, aircraft integration, and installation; kit and integration costs vary with aircraft requirements. The plan lists 146 A-kits, 90 antennas, 10 spares, and 334 installations for that year, with implementation through Modification Work Orders.

Embedded GPS Inertial Navigation System EAGLE-M B Kit upgrades the EGI navigation system to receive and process the secured military-code, or M-Code, GPS signal. Enhanced Aviation Global air-traffic management Localizer Performance with Vertical Guidance EGI (EAGLE-M) also enables precision navigation and approaches in civil and military airspace. Its design supports future ALT-PNT functions and other upgrades for Multi-Domain Operations in contested GPS environments. The Army procures three core EAGLE-M baseline configurations with differing capabilities and aircraft functionality; subject to funding, retrofit kits offer recurring cost savings that can support additional units.

For fiscal year 2027, the EAGLE-M plan provides for 43 new units, 40 new spares, aircraft integration, test and evaluation, shared services, and 353 installations. Honeywell Incorporated of Clearwater, Florida, is the listed manufacturer, and installations use Modification Work Orders. The MAGNA and EAGLE-M production plans both show December 2026 contract dates and November 2027 delivery dates for their fiscal year 2027 entries. These acquisition and installation activities turn receiver and antenna purchases into usable aircraft capabilities rather than treating equipment procurement alone as the modification.

The fiscal year 2027 request increases from fiscal year 2026 principally because it buys more MAGNA A-kits and B-kits and funds their associated installation to meet platform requirements. Across the line, that year's funding also supports EAGLE-M B-kits and system evaluation in air vehicles. The Department of War's purchasing constraint under Section 913 of the fiscal year 2011 National Defense Authorization Act limits procurement of GPS user equipment beyond fiscal year 2017 unless it can receive M-Code, reinforcing the role of the EAGLE-M upgrade. Planned procurement and installation continue in subsequent years as the Army fields these complementary layers of PNT assurance.
