### Project 651030 — GPS Receiver Development

Positioning, Navigation, and Timing (PNT) solutions are critical to offensive and defensive operations, enabling delivery of precision fires, safe aerial navigation, and time coordination across multiple platforms and subsystems. PNT must be maintained in the face of emerging and continuously evolving adversarial electronic and cyber threats, requiring increased system resiliency and rapid adaptability. Evolving threats will drive upgrades such as Global Positioning System (GPS) receiver modernization, development of standard navigational system formats/interfaces, increased use of open system architecture design principles, incorporation of alternative navigation sources into navigational solutions, advanced anti-jam antennas, antenna electronics, radio frequency monitoring/locating/reporting capabilities, and precision clock improvements to maintain current and future force capabilities. GPS Receiver Development includes Embedded GPS/Inertial Navigation System (INS) Modernized (EGI-M), Miniaturized Airborne GPS Receiver 2000 Modernization (MAGR-2K-M), Resilient GPS (R-EGI) development, PNT Software Defined User Equipment (PNT SDUE), anti-jam antenna/antenna electronics development, situational awareness devices, and other advanced/non-GPS PNT solutions. Activities also include, but are not limited to, current program planning, rapid prototyping/advanced technology and concept development, execution, and future program planning and support to other GPS enabled systems as required. The PNT Resiliency, Mods, and Improvements (RMI) effort provides rapidly re-programmable application space for Alternate Satellite Navigation Systems User Equipment (UE), enabling agile and resilient response to GPS threat environments. Funds may be used to address emerging and short-notice Diminishing Manufacturing and Material Shortage (DMSMS) issues. Beginning in FY 2027, GPS Receiver Development project will include MGUE Inc 1 and Inc 2 efforts. MGUE Inc 1 program leverages technology to the maximum extent while addressing the production of M-Code integrated circuits far into the future.

**Named R-3 performers** (share of this project's FY2027 R-3 total, so they need not reach 100%)**:** IS4S (296.1, 42%), Northrop Grumman (58.7, 8.3%), RTX / Raytheon (24.7, 3.5%), Technology Adv. Group (9.2, 1.3%).

## Mission & acquisition strategy

Positioning, Navigation, and Timing (PNT) solutions are critical to offensive and defensive operations, enabling delivery of precision fires, safe aerial navigation, and time coordination across multiple platforms and subsystems. PNT must be maintained in the face of emerging and continuously evolving adversarial electronic and cyber threats, requiring increased system resiliency and rapid adaptability.

Beginning in FY 2027, GPS Receiver Development includes projects Military Global Positioning System User Equipment (MGUE) Increment 1 and Increment 2. MGUE Inc 1 program is responsible for the development of standard modernized receiver form factors for the lead platforms. The program received direction in February 2014, from the Under Secretary of War for Acquisition and Sustainment to execute a new acquisition strategy, accelerating the program to provide test units faster to facilitate military end users. The MGUE program received a Milestone B decision in January 2017.
