FCC Releases NOI Examining Alternatives to GPS

The FCC posted Friday a notice of inquiry on alternatives to GPS for positioning, navigation and timing (PNT), approved by commissioners 4-0 Thursday (see 2503270042). “Relying on GPS alone as the primary source of PNT data leaves America exposed to a single point of failure and leaves our PNT system open to disruption or manipulation by adversaries,” the notice says.
