This invention provides a fully digital wireless time and frequency synchronization system and method, applicable to the fields of positioning, navigation, and timing technology. The system includes: a signal transceiver module for bidirectional time transmission with a master node via a wireless channel and recording transmission and reception timestamps; a time measurement module for calculating time and frequency deviations based on the timestamps and generating a digital frequency control word; a microelectromechanical system (MEMS) oscillator module for receiving the frequency control word via a digital interface and adjusting the output frequency in real time; and a synchronizer module for generating a second pulse signal based on the adjusted frequency. The adjusted frequency is fed back to the signal transceiver module as a local clock driver, forming a closed-loop frequency control. This invention deeply integrates high-precision time measurement with a MEMS resonator, achieving fully digital closed-loop control. While maintaining advantages such as small size, low power consumption, and vibration resistance, it significantly improves the transient response speed and long-term stability of frequency synchronization and supports rapid customization of special frequency points.
