Pulsar-0, launched on a SpaceX Falcon 9 rideshare on July 1, 2025, is Xona Space Systems’ first in-orbit test of a low-Earth navigation network aimed at boosting signal strength and accuracy beyond GPS.
100-times-stronger signals from low Earth orbit could improve positioning in dense cities, under foliage and indoors, while also resisting growing GPS jamming that is disrupting aviation, shipping and smartphone services.
Live-sky jamming tests in multiple countries showed Pulsar signals could cut a jammer’s effective area by 95%, and software updates improved the satellite’s native positioning accuracy from a 4.2-centimeter ranging error to 1.5 centimeters.
Six production satellites are scheduled to launch in October 2026, with early service in 2027 and intermittent timing coverage for mid-latitude customers in sectors including finance, telecoms, data centers and transport.
Xona ultimately plans a 258-satellite constellation that it says could deliver global positioning accuracy within several centimeters, offering a potential alternative layer for navigation and timing as interference risks rise.
As commercial satellites promise flawless indoor GPS, how will this reshape our daily lives?
With private companies selling precision location, will reliable navigation become a paid luxury?
Xona’s new satellite network is jam-proof, but what is its hidden vulnerability?
