Elevation-cutoff-dependent convergence and steady-state performance of LEO-augmented multi-GNSS PPP time transfer

Under restrictive elevation-cutoff conditions, Global Navigation Satellite System (GNSS) precise point positioning (PPP) time transfer can suffer delayed convergence because fewer satellites are available and the timing geometry degrades. However, it remains unclear whether low Earth orbit (LEO) geometric augmentation...
