California Leads Efforts to Develop GPS Backup System Amid Rising Interference Concerns
California is spearheading the development of a backup system for GPS, a critical technology increasingly vulnerable to interference. Recent incidents, such as GPS jamming affecting a 40-mile expanse of airspace near Dallas-Fort Worth International Airport and navigation problems for United Airlines flights near Los Angeles International Airport, highlight the urgent need for such a system. Internationally, widespread jamming has been observed in the Middle East, and Russian satellites have been interfering with GPS signals across Europe. Russia and China already possess ground-based complements and backups to GPS, recognizing the severe consequences of a compromised GPS system for telecommunications, public safety, and defense. A one-day GPS outage could cost the American economy $1.6 billion, according to an economic analysis by The Brattle Group. California is currently testing the world's first ground-based, 5G-powered 3D Positioning, Navigation, and Timing (PNT) system in Santa Clara County, which aim...
