L3Harris Technologies has reached a milestone by delivering 100,000 Military-Code (M-Code) GPS receivers to US and allied forces.
M-Code receivers provide secure, jam-resistant positioning, navigation, and timing (PNT) essential for operations in contested environments where satellite signals can be disrupted by jamming, spoofing, or cyber-enabled interference.
The deliveries were made under the Modernized GPS User Equipment (MGUE) Increment 1 program, part of decades of GPS modernization by L3Harris to ensure warfighters have trusted navigation and timing data in electromagnetically challenged scenarios.
These receivers strengthen air, ground, and maritime operations and support systems ranging from precision weapons to autonomous vehicles and joint command-and-control networks.
“As the global threat environment continues to evolve, secure and resilient PNT has never been more critical to ensuring operational advantage,” L3Harris President of Advanced Effects and Missile Solutions Quinlan Lyte said.
Countries Deploying M-Code and Modernized Receivers
Allied nations started integrating M-Code-enabled MGUE as part of broader cooperation with the US on resilient positioning, navigation, and timing systems.
In 2021, a US Space Force multinational arrangement authorized participating nations — including Canada, France, Germany, South Korea, and the UK — to receive MGUE Increment 1 technology for laboratory and field testing, with additional interest expressed by Australia, Italy, the Netherlands, and Sweden.
Independent allied deployments of jam-resistant GPS products also illustrate the global trend toward modernized navigation.
In 2022, BAE Systems delivered M-Code-capable miniaturized GPS receivers to the German Army, making Germany the first non-US customer for that type of jam-resistant military GPS technology.
Beyond GPS specifically, NATO partners are broadly upgrading command, control and communications systems that incorporate secure PNT elements.
For example, in April 2025 the Dutch Ministry of Defence selected advanced L3Harris Falcon IV radios in a multi-billion-euro deal to enhance interoperable tactical communications across its armed forces.
