L3Harris Technologies has delivered its 100,000th M-Code GPS receiver to US and allied militaries, marking a key milestone in strengthening secure navigation and timing capabilities.
Designed for operations in contested environments, M-Code receivers provide protected positioning, navigation, and timing (PNT), ensuring resilience against jamming, spoofing, and cyber-enabled disruptions. The deliveries fall under the Modernized GPS User Equipment (MGUE) Increment 1 program, a central element of ongoing GPS modernization efforts to provide reliable data in complex electromagnetic conditions.
These receivers enhance mission effectiveness across air, land, and sea operations, supporting applications ranging from precision strike systems to autonomous platforms and integrated command networks.
Adoption of M-Code-enabled systems is growing among US allies as part of collaborative efforts to strengthen resilient PNT capabilities. In 2021, the United States Space Force approved a multinational initiative allowing countries such as Canada, France, Germany, South Korea, and United Kingdom to test MGUE Increment 1 systems, while others—including Australia, Italy, Netherlands, and Sweden—have shown interest.
Separate efforts also reflect the global move toward advanced GPS technologies. In 2022, BAE Systems supplied miniaturized M-Code-enabled receivers to the German Army, making it the first non-US operator of such equipment.
Meanwhile, broader modernization initiatives among NATO members include upgrades to command, control, and communications systems that incorporate secure PNT elements. Notably, in April 2025, the Dutch Ministry of Defence selected L3Harris Falcon IV radios in a major contract to enhance interoperable communications across its armed forces.
