Starlink Shuts Down Access to GPS Alternative Feature

Starlink is shutting down a GPS-style feature that most of its customers likely never realized existed. The shutdown of the Starlink location feature will not dampen broader momentum toward using the satellite constellation as a navigation alternative, especially as GPS jamming and spoofing have become more widespread worldwide.

The Starlink constellation is designed to provide communications services first and foremost. SpaceX publicly acknowledged in a May 2025 letter to the US Federal Communications Commission that Starlink could deliver positioning, navigation, and timing (PNT) services. A handful of savvy Starlink customers had been accessing Starlink PNT capability for several years until the recent decision to shut it down, according to PCMag.

The built-in location feature was previously accessible through the Starlink mobile app’s Debug Data section. It enabled users to give local networks access to their Starlink dish’s precise latitude, longitude, and altitude with no authentication required, according to software developer Paul Sutherland’s blog post. Starlink dishes have their own GPS receivers to pinpoint locations so they can find the nearest satellites, but the feature also offered an option to use Starlink positioning exclusively.

Todd Humphreys, director of the Wireless Networking and Communications Group and the Radionavigation Laboratory at The University of Texas at Austin, has described the Starlink PNT capability as a “cheat code for those who knew about it” because it worked in regions with GPS interference. In correspondence with Ars Technica, Humphreys said, “The beauty of Starlink as a backup to GNSS is that it’s such a different system—frequencies 10 times higher, bandwidths 10 to 100 times wider, power 100 to 1,000 times stronger, satellites 100 times more proliferated.”

The capability proved especially useful for users who installed the latest Starlink dishes on recreational vehicles and boats. In one case study highlighted by PCMag, a sailboat cruising through the Red Sea with the Starlink Mini dish—a user device released in 2024—was able to exclusively rely on Starlink positioning data despite GPS jamming and spoofing.

On April 21, Starlink users received email notifications telling them that dish location data would no longer be available as of May 20, 2026. There was no specific rationale given for the decision, and SpaceX did not respond to an Ars Technica request for comment.

GPS jamming and spoofing have become widespread, impacting shipping routes from Europe to Asia and disrupting hundreds of flights on a daily basis. Jamming involves broadcasting strong signals to overpower the relatively weak radio signals coming from GPS and other global navigation satellite systems. Spoofing relies on transmitting false signals that mimic authentic satellite signals to trick receivers into calculating erroneous positions. Starlink’s low-Earth orbit satellites transmit higher-power signals in the Ku-band with wider bandwidths that are difficult for adversaries to disrupt. Starlink is also much more resilient to spoofing because its user dishes are phased array antennas capable of focusing in the direction of a fast-moving Starlink satellite to detect.
