GNSS Disciplined Systems

Precision timing is at the heart of GNSS disciplined systems. With our increasingly connected world, a consistent GNSS signal is more critical than ever. SiTime offers highly reliable and ultra-robust MEMS timing solutions that manage the incoming GNSS signal and filter wander to maintain signal lock. If the satellite signal is obstructed or not available, SiTime’s precision devices can keep the system running until the reference is restored.
