New navigation satellites in low-Earth orbit could provide 100 times stronger signal strength compared to GPS and other global navigation satellite systems operating from higher orbital altitudes—enabling greater location accuracy within dense cities, under thick foliage, and even inside buildings. Such signals would also likely prove more resilient to interference at a time when commercial flights, maritime shipping, and even various smartphone apps face increasingly widespread disruption from GPS jamming.
That vision may start to take shape when the first six production satellites of California-based Xona Space Systems are scheduled to launch in October 2026, with early service starting in 2027. Once the full constellation of 258 Pulsar satellites has been launched in the following years, Xona claims that customers will be able to accurately pinpoint their locations anywhere on Earth to within several centimeters.
“That added power means that we can get into that indoor environment that GPS can't get to today,” Adrien Perkins, co-founder and VP of engineering at Xona Space Systems, told Ars. “Our higher power allows you to get into those jamming environments a lot further than you would with GPS by itself.”

Scientists have found a way to make GPS remarkably accurate in city “urban canyons,” where navigation has long gone wrong. Most of us trust that the location shown by our GPS is accurate. But anyone who has tried navigating an unfamiliar city knows that is not always the case. You may be walking steadily down [...]
Russian satellites have been identified as the cause of mysterious, seconds-long bursts of GPS interference across Europe—a rare example of human-made GPS interference coming from space. But uncertainty still hangs over whether such interference is intentional and if it could be more powerfully weaponized as GPS jamming with continental reach in the future.
The discovery came from an investigation detailed in a June 2 preprint paper by Todd Humphreys and his student Zach Clements at The University of Texas at Austin, along with Argyris Kriezis at Stanford University in California. By sifting through public data from ground-based stations with global navigation satellite system (GNSS) receivers, they identified a pattern of high-powered interference lasting less than 10 seconds each time but simultaneously detectable by ground stations across Europe from Norway to Spain to Poland, and even reaching as far west as Greenland and Canada.
By analyzing the ground station data from January 2019 to April 2026, the researchers found 75 days with at least one widespread GNSS interference event overlapping with the GPS L1 frequency band centered on 1575.42 megahertz. That represents the main band used for signal transmission by the US-made GPS satellite constellation and GNSS constellations from other countries.

GPS is commonly treated as a way to find a route or track a delivery. In critical infrastructure, its quieter function is often more consequential: it distributes precise time that helps far-flung systems agree on when something happened. That shared time base supports cellular and broadband networks, parts of the electric grid, and regulated timekeeping […]

NASA satellites designed to observe cyclone wind speeds and collapsing ice sheets have also proven capable of identifying the approximate locations of GPS jammers. That could help monitor high-risk areas for aircraft and ships navigating the growing prevalence of GPS interference worldwide.
Two different NASA satellite systems showed how they could locate a known but mysterious GPS jammer within several kilometers of its position in Iran, according to an experiment by Sean Gorman, CEO and cofounder of the location-based technology company Zephr.xyz that was detailed in the magazine GPS World. Such jammers use strong signals to overpower the weaker radio signals coming from US-operated GPS satellites and other global navigation satellite systems.
Such NASA satellites cannot perform “near-real time monitoring” or pinpoint the exact location of GPS jammers, said Clara Chew, principal scientist and lead of the GNSS systems and data team at the California-based satellite manufacturer Muon Space, who was not involved in the study. But Chew told Ars that identifying the approximate locations of GPS jammers “could potentially be helpful for flight planning” or for “indicating high risk areas for maritime shipping.”
