GPS Modernization Acceleration Act

Key Points

• The bill requires the President to speed up modernizing the GPS system within 180 days of becoming law, including launching new GPS III satellites and upgrading ground control systems.
• Congress points to 15 GPS satellites still operating past their intended lifespan with outdated signal technology, creating vulnerabilities in a system used for military operations and everyday civilian services.
• The bill highlights that adversaries are actively jamming or spoofing GPS signals, threatening both national defense and public safety functions that rely on accurate positioning and timing.
• New, harder-to-block signals like L5 would be prioritized for both civilian and military use to make the system more resistant to interference.
• The Defense Department and Transportation Department must report to Congress every year for three years on funding, progress, and strategies to counter GPS jamming and spoofing.
