The National Telecommunications and Information Administration (NTIA) has published a Notice and Request for Comment (RFC) on the potential impact of the increasing deployment of satellite-enabled direct-to-device (D2D) services in the 1610-1660.5 MHz (L-band) on GPS operations at 1575.42 MHz (the GPS L1 Signal). While inviting comment on interference risks generally, NTIA raises specific concerns regarding D2D interference with GPS systems onboard aircraft that support aircraft navigation and safety operations. The RFC includes a technical analysis by the U.S. Department of Transportation (DOT) detailing aviation safety concerns and seeks comment on potential mitigation strategies. Comments are due on February 10, 2025.
