Product Description
The T200 GPS/BeiDou Synchronized Clock Module integrates signals from various satellite navigation systems and can be equipped with up to three different manufacturers' GPS/BeiDou dual-mode positioning or timing modules. By employing rational fusion algorithms, it achieves superior time and frequency performance compared to single-system or single-positioning modules. Multiple synchronized frequency signals are utilized to control the oscillator, enhancing its precision.
This module provides reliable timing and frequency signals, generating a recurring 1 pulse per second (1pps) and time signal when satellite signals are not properly received, ensuring adaptability in cases of signal loss within a short period. It offers multiple time publication interfaces to meet various external application needs.
Frequency and 1pps Generation Technology Combining Frequency Modulation and Phase Modulation:
The 1pps time information is derived by dividing the 10 MHz signal output from the GPS-disciplined oscillator by 10,000,000. It is then combined with the 1pps signal generated by the GPS/BeiDou module. This fusion process results in a 1pps signal with excellent short-term and long-term stability. Frequency modulation and phase modulation techniques are used for frequency control, ensuring both frequency accuracy and phase consistency with the 1pps signal. This feature is particularly well-suited for applications with demanding requirements such as digital video broadcasting and CDMA.
