Strengthening Satellite Navigation: New Resilient LEO PNT System

This Act directs the U.S. Air Force to test a commercial Low Earth Orbit (LEO) satellite system as a more reliable alternative to the existing GPS. The goal is to create a system highly resistant to jamming and outages, ensuring greater security and accuracy for all users. Crucially, the new system must be compatible with current civilian GPS devices without requiring hardware modifications.
Key points
Mandates a demonstration project for a new, resilient Positioning, Navigation, and Timing (PNT) system using commercial LEO satellites.
The new system must operate independently of GPS and be significantly more resistant to signal jamming and spoofing threats.
The technology must work with existing civilian GPS equipment (L1 or L5) without requiring users to modify or replace their hardware.
The project aims for high accuracy (positioning under 30 cm) and rapid service restoration after potential satellite failures.
