摘要：
In a time-frequency system as an important part used in the satellite navigation, timing and positioning systems, often requires processing of high-precision time and frequency signals. It includes frequency conversion, frequency and phase adjustment, frequency, phase and time measurement and control, the guarantee of the frequency accuracy, stability and phase noise performance of the output time-frequency signal and so on. To achieve the above requirement of the time and frequency processing, besides the communication and connection with the other devices in the total system, we also developed multi-level time interval measurement and synchronization control technology between 1pps signals with the ps resolution, ultra-high stability crystal oscillator and its phase-locked technology with 10-13/s stability for 10MHz, 10.23MHz frequency signals, ultra-high resolution phase detection technique higher than ps resolution, parallel the accuracy improvement technology of time-frequency detection devices, system noise restraint and software processing technology, and the processing and compensation technology of the different systematic errors of high precision frequency sources (second-class atomic clock, and high stability crystal oscillator) based on the time-frequency processing system resources. These technologies will enhance the overall performance specifications of the corresponding systems.
