In today’s contested battlespace, access to positioning, navigation and timing (PNT) provided by military GPS is no longer a given. Adversaries are increasingly capable of disrupting satellite signals through jamming, spoofing and cyber-enabled interference, which can undermine operational effectiveness if left unaddressed. For the United States and allied forces, resilient GPS has become a foundational requirement for mission success.
A Legacy of GPS Modernization
For more than four decades, L3Harris Technologies has been at the forefront of GPS modernization, ensuring warfighters have trusted navigation and timing data in challenged electromagnetic environments. That legacy of innovation and execution recently reached a significant benchmark with the delivery of the 100,000th next-generation Military-Code (M-Code) GPS receiver to the United States and allied partners through the Modernized GPS User Equipment (MGUE) Increment 1 program.
What M-Code Delivers on the Modern Battlefield
M-Code receivers are designed to deliver secure, jam-resistant PNT capabilities that are essential as military operations grow more distributed, joint and technologically complex. Unlike legacy systems, M-Code-enabled receivers provide enhanced security features and increased resistance to interference, allowing forces to maintain trusted GPS access when signals may otherwise be degraded or denied.
“As the global threat environment continues to evolve, secure and resilient PNT has never been more critical to ensuring operational advantage,” said Quinlan Lyte, President, Advanced Effects, Missile Solutions, L3Harris. “Reaching this delivery milestone reflects our team’s sustained commitment to equipping the warfighter with reliable technology designed to perform in the most contested environments.”
Scaling Mission-Ready Capability Across the Force
Beyond the milestone itself, the scale of fielded MGUE Increment 1 receivers underscores a broader shift toward modernized, mission-ready GPS capability across U.S. and allied platforms. From air and ground systems to maritime and joint operations, M-Code technology is helping commanders operate with greater confidence in environments where GPS reliability can no longer be assumed.
Advancing the Next Phase of GPS Modernization
L3Harris is building on the momentum from MGUE Increment 1 as the company advances the next phase of GPS modernization through MGUE Increment 2. Ongoing development includes a new M-Code-enabled application-specific integrated circuit and the TruTrak-M Type II receiver, technologies designed to further improve size, weight, power and cost efficiencies while maintaining robust security and performance. These advancements will enable greater integration and flexibility, as well as broader adoption across future platforms.
The L3Harris TruTrak-M Type II GPS Receiver Module exceeds MGUE technical requirements, delivering reliable, mission-critical performance.
Keeping the Mission on Course
As military operations evolve to meet emerging threats, assured PNT remains a quiet but indispensable enabler of mission success. By pairing decades of experience with continued investment in next-generation technology, L3Harris is helping ensure that when it matters most, the signal remains secure and the mission stays on course.
