The Federal Communications Commission (FCC) plans to vote on an inquiry to explore alternatives to GPS, FCC chair Brendan Carr says in a blog post. Carr says that while GPS has been “indispensable,” the technology “isn’t infallible” and that “disruptions to GPS have the potential to undermine the nation’s economic and national security.

The Federal Communications Commission is making a push for the US to develop alternatives to GPS, opening the door for satellite systems like SpaceX’s Starlink to play a role. FCC Chair Brendan Carr will ask the commission to vote later this month on starting a formal inquiry to explore GPS alternatives.

The U.S. Federal Communications Commission said on Wednesday it plans to vote next month to explore alternatives to GPS after national security concerns have been raised about relying on a single system crucial to modern life.

“On Earth we can use GNSS signals to navigate in everything from smartphones to airplanes,” Kevin Coggins, deputy associate administrator for NASA’s SCaN (Space Communications and Navigation) Program, said in a statement. “Now, LuGRE shows us that we can successfully acquire and track GNSS signals at the Moon.”

NASA has successfully deployed GPS technology on the Moon, enabling Firefly Aerospace's Blue Ghost lunar lander to navigate and set distance records from Earth.
