This bill directs the President to speed up the modernization of the Global Positioning System (GPS), which is used by the military, transportation systems, utilities, and countless civilian applications. The legislation requires the development and deployment of newer GPS III satellites, an upgraded control system to manage the satellite constellation, and new signal technologies like L5 that would make GPS more secure and resistant to jamming and interference from foreign adversaries. Within 180 days of the bill's enactment, the President must create clear timelines for deploying a full constellation of 24 modernized satellites and upgrading ground infrastructure, while coordinating efforts across the Defense Department, Transportation Department, and other relevant agencies. The bill also requires the Secretary of Defense to submit progress reports to Congress every year for three years, detailing funding needs, modernization progress, and strategies to protect GPS from interference and spoofing attacks. No specific funding amount is allocated in the bill itself, but it identifies the need for additional resources and asks agencies to report on their budget requirements.
