To replicate the performance of GPS, a satellite navigation system in low-Earth orbit would need about 10 times more satellites than a similar satellite constellation in medium-Earth orbit, Kassas explained. But as the recent rise of Xona and other competitors shows, lower manufacturing and launch costs have made it possible to build and launch such a satellite constellation dedicated to delivering PNT services from low-Earth orbit.
