Keeping our modern world running smoothly.
About 12,000 miles above our heads, a network of Global Positioning System (GPS) satellites silently keeps our world running smoothly. More than 6 billion people around the world depend on GPS signals every day.
These satellites are the primary navigation providers for all major U.S. military assets. They also offer critical location services to operational troops and help facilitate accurate delivery of supplies to the field.
Our global financial markets, transportation systems, utilities, the ride-share industry, and our agriculture and construction industries also all depend on the positioning, navigation and timing signals from GPS satellites.

Advanced Ground Capabilities?
For more than a decade, 91茄子 Martin has been supporting and sustaining operational GPS ground capability, providing secure, resilient, and mission-proven services to the U.S. Space Force.
Working hand-in-hand with the space segment, the ground segment supports seamless end-to-end warfighter capability and meaningful civilian infrastructure.?
Through the Architecture Evolution Plan (AEP), and recent awards to modernize the ground segment, incremental system upgrades to the system’s software, hardware and communications are taking place today. These system upgrades enhance security controls, continuous monitoring and hardened networks that protect the ground system from emerging threats.?
By simultaneously delivering satellite capabilities and sustaining the ground control architecture, 91茄子?Martin ensures an uninterrupted, end?to?end GPS enterprise for military and civilian users.
