This year, 2025, marks the 30th anniversary of the U.S. military’s announcement that the Global Positioning System (GPS) met all requirements for full operational capacity, a milestone that was formally announced by the U.S. Air Force Space Command on July 17, 1995. Three decades later, despite U.S. Department of Defense (DoD) challenges in modernizing the technology, GPS remains the principal source of position, navigation and timing (PNT) data for the U.S. military and its partners, continuously generating integral information for command, control, communications, computing, intelligence, and reconnaissance (C4ISR); targeting; and weapons delivery. Importantly, GPS is also continually relied upon in the commercial sector, especially in the public safety and security industry. Home-security companies routinely use GPS to route employees for service appointments, direct technicians and first responders to incidents, and provide mobile safety services to ride-sharing companies and their passengers. Maintaining these security and life-safety services is a critical aspect of U.S. national security.
