The European Space Agency (ESA)'s LEO-PNT (Low Earth Orbit Positioning, Navigation and Timing) demonstrator mission will feature a 10-satellite constellation demonstration mission that will assess how a low Earth orbit fleet of satellites can work in combination with the Galileo and EGNOS constellations in higher orbits that provide Europe’s own global navigation system. This launch will lift 2 “Pathfinder A” satellites built by Thales Alenia Space and GMV to a 510 km altitude Low Earth Orbit.
