Lockheed Martin has successfully completed the core mate phase of GPS IIIF Space Vehicle 11 ( SV11), a critical production milestone that marks the satellite’s formal “birth.” <p>Continued manufacturing and deployment of these next-generation GPS spacecraft is essential to maintaining reliable global coverage, with the GPS IIIF block introducing a suite…
Low-Earth orbit (LEO) systems have emerged as a promising complement to GNSS, offering higher received power, better satellite geometry and broader spectrum options. Researchers aim to evaluate whether LEO-PNT can complement or enhance GNSS performance through large-scale simulations and design…
Astroscale of the UK will provide Xona Space Systems with next-generation docking plates for integration into Xona’s growing constellation of low Earth orbit (LEO) satellites. The collaboration supports two critical goals: building a resilient positioning, navigation and timing (PNT) infrastructure…
The Pentagon’s first batch of new and more capable GPS satellites, part of the GPS IIIF program, is facing significant delays. The first batch is eight to eleven months behind schedule, which the U.S. Space Force attributed to manufacturing difficulties encountered…
