A high-precision time synchronization (HTS) system and method using virtual atomic clocks (VACs) includes: providing an implementation of VAC generation method: accessing the high-precision time service provided by the WPT system, solving receiver clock offsets and reconstructing reference stations observations; providing a rapid HTS method: using the VAC information to realize rapid HTS by means of pseudorange or carrier phase CV time transfer; obtaining a HTS system using VACs, including a real-time observations receiving and distributing module, a differential corrections receiving and decoding module, a local clock solving module, a GNSS observations reconstruction module, and a VAC data broadcasting module. Aiming at VACs don't have the function of time-keeping, and GNSS is easy to be interrupted by factors such as environmental and network anomalies, and a VAC is unable to continuously provide high-precision time service, combing VACs is proposed to safeguard the continuity and reliability of the time-frequency service system.
