Hardware-in-the-loop verification of GNSS-based orbit determination, time synchronization, and oscillator disciplining for LEO-PNT
Positioning, navigation and timing (PNT) services from low Earth orbit (LEO) present an important alternative or complement to established global satellite navigation systems (GNSSs). Within a LEO-PNT system, proper knowledge of the instantaneous LEO satellite position and onboard time is essential for the generation o...
