Enhancing the continuity and robustness of Galileo HAS PPP time transfer with a novel adaptive clock model

Precise point positioning (PPP) is a cornerstone technology for delivering high-precision spatiotemporal transfer in Global Navigation Satellite Systems (GNSSs). Although the Galileo high accuracy service (HAS) improves static PPP timing and time transfer, practical applications remain limited by observation noise, tim...
