Lockheed Martin has secured a $105-million US Space Force contract to sustain and upgrade its Global Positioning System (GPS) ground control network.
This GPS ground segment supports positioning, navigation, and timing services used by military and civilian users.
The work builds on more than a decade of upgrades under the US Space Force’s Architecture Evolution Plan. It covers launch, early orbit operations, and disposal support for GPS IIIF satellites, alongside continued improvements to the resilience and performance of the wider GPS enterprise.
A key focus of the effort is strengthening M-Code capabilities used by the US military for secure navigation in contested environments where GPS signals may be disrupted or jammed. The system also underpins civilian infrastructure, including banking, transportation, and utilities.
Lockheed Martin said the program supports continuity of service while enabling integration of next-generation satellites designed to improve signal strength and reliability.
The company is also producing GPS IIIF spacecraft at its Denver facility after completing the GPS III line.
These newer satellites are designed to deliver higher anti-jam performance and improved accuracy compared with earlier generations, reinforcing the broader GPS architecture as additional spacecraft enter orbit.
US Space Force Modernization Efforts
The latest deal forms part of a broader set of ongoing efforts by the US Space Force to strengthen and modernize its capabilities.
In April, the service awarded L3Harris a $150-million contract to maintain and upgrade ground systems used to track objects in space and improve early warning capabilities. The company will also upgrade sensors and command-and-control tools to improve space awareness and threat detection.
In March, BAE Systems completed a design review for a US Space Force missile-tracking satellite program, which aims to deploy 10 satellites and supporting ground systems for command, control, and data distribution.
CACI International secured a five-year task order in January, valued at up to $212 million, to upgrade network infrastructure across US Space Force installations.
