Assessment of Light Squared Terrestrial Broadband System Effects on GPS Receivers and GPS-dependent Applications

The Executive Steering Group (ESG) of the National Executive Committee (EXCOM) for Space-Based Positioning, Navigation, and Timing (PNT) directed the National Space-Based PNT Systems Engineering Forum (NPEF) to conduct an assessment of the effects of LightSquared’s planned deployment of a terrestrial broadband network to Global Positioning System (GPS) receivers and GPS-dependent systems and networks.
