Product Description
The T710M GPS Rubidium Atomic Module consists of a high-precision timing GPS receiver, high-performance rubidium atomic clock, low-phase-noise phase-locked circuit, control module, and high-precision filtering module. By utilizing digital phase-locking technology, it combines the long-term stability of GPS and the low aging characteristics of rubidium atomic clocks, resulting in a low-phase-noise high-precision rubidium atomic frequency standard with long-term stability and high accuracy. When in GPS lock state, the stability of the 10MHz frequency can reach the performance of a regular cesium clock, offering excellent cost-effectiveness.
The T710M GPS Rubidium Atomic Module outputs a 1PPS signal derived from the frequency signal of the rubidium atomic clock and synchronized with the UTC time output by GPS. Compared to the original second pulse of GPS, the frequency-divided pulse is smoothed, overcoming the influence of original pulse fluctuations and jumps, and serving as a reproduction of UTC time reference. When the GPS signal is lost or abnormal, the device can intelligently recognize it and automatically switch to the rubidium atomic clock timing mode, providing a highly stable time frequency signal continuously.
