U.S. Losing Leadership in Space-Based Navigation, Expert Warns

Former Pentagon space policy official Marc J. Berkowitz warns that the U.S. has lost its leadership in space-based positioning, navigation, and timing (PNT), affecting both critical infrastructure and military operations. The aging GPS constellation remains vulnerable to jamming and spoofing, posing security risks. Berkowitz stresses the urgent need to deploy GPS IIIF satellites, which feature enhanced encryption and anti-jam capabilities. While the U.S. Space Force’s Resilient-GPS program aims to strengthen navigation with smaller satellites, Berkowitz argues it may not fully counter cyber and electronic warfare threats. The analysis underscores growing concerns over U.S. space security and military readiness.
