Xona Space Systems is developing a constellation of 258 low-Earth orbit satellites called Pulsar to provide a GPS alternative with 100x stronger signals, enabling centimeter-level accuracy indoors and in dense urban areas, with initial launches planned for October 2026.
An experimental satellite has mapped GPS jamming across Europe and the Middle East, revealing a larger scale of interference than expected. The findings highlight vulnerabilities in GNSS signals and the need for more resilient navigation systems.
