Bridge, Tunnel & Turnpike Association Asks for Tweak to GPS NOI

A lawyer for the International Bridge, Tunnel & Turnpike Association spoke with an aide to FCC Chairman Brendan Carr to ask about adding a question to the commission's draft notice of inquiry on alternatives to GPS for positioning, navigation and timing (PNT). Commissioners are slated to vote on the NOI on March 27 (see 2503060061). NextNav’s proposal for PNT in the 900 MHz band has long been controversial. The NOI should ask about “interference implications for incumbent spectrum users associated with any of the PNT solutions discussed in this NOI,” the association said in a filing posted Monday in docket 25-110. “The addition of this question will produce a more complete record to support Commission decision-making.”
