Preprocessing for fast synchronization of high-stability oscillators disciplined by GNSS 1 PPS signal

摘要

This paper presents a novel algorithm for preprocessing of pulses coming from GNSS and signals produced locally by a rubidium oscillator to reduce synchronization time without changing the main algorithm of the control loop. Moving average and Kalman filtration were used as the preprocessing methods. The experimental results for different rubidium oscillators are presented.
