SpaceX has submitted reply comments to the FCC describing how its Starlink LEO satellite system currently provides and could further support positioning, navigation, and timing (PNT) services.

The filing was submitted as part of the FCC’s ongoing Notice of Inquiry (NOI) into promoting resilient and diverse PNT capabilities across the United States.

It states that Starlink’s capabilities are not hypothetical and have been demonstrated under real-world conditions.
