u00a0u00a0SDI-316 is a high accuracy timing system, which uses Kalman filteringu00a0and Closed-loop control theory. u00a0Phase-locked loopu00a0is adoptedu00a0in taming Rubidium oscillator and constant temperature crystal oscillator,so it canu00a0stillu00a0output high-stable timing synchronous signal and standard-frequency signal in a period of timeu00a0even interference happens.
1.High stable synchronous signal
2.self-learning and adjusting
3.keep outputting signal when reference signal interrupts
