System and method for implementing rubidium clock aging compensation

Abstract

This invention provides a system and a method for compensating aging of Rb clocks, which compares the clock frequency to be tested with a reference clock frequency and computes the measured result to get a compensation value to be sent to the being tested Rb clock to realize the compensation or introduces a management terminal and the test module transmits the compensation value and the test result to the management terminal by Ethernet, at the far end, the compensation value is sent to the being tested Rb clock artificially or automatically by the management terminal to realize the compensation to the aged Rb clock.

Description

technical field [0001] The invention belongs to the field of electronic communication, and in particular relates to a system and method for realizing aging compensation for rubidium clocks. Background technique [0002] Rubidium clock is an atomic oscillator with high stability and high accuracy, which is widely used in aerospace, national defense communication, electronic information, instrument measurement and other fields. Rubidium clocks use the stimulated radiation of rubidium elements to produce clock references with high stability, high accuracy and low aging rate. The existing commercial rubidium clocks in the field of communication generally cooperate with satellite signal receivers, and combine the good long-term stability of satellite timing signals and the good short-term stability of rubidium clock signals to generate a primary reference clock LPR for communication, which is used as a digital synchronization in communication networks The highest base clock for ...

Problems solved by technology

However, this method needs to carry a large number of instruments to the scene, and the antenna of the satellite signal receiver must be placed outside the window or on the roof of the building, but the general telecom operator's computer room cannot allow the antenna to be placed on the roof or outside the window at will; it requires high labor costs and material resources Cost, if the rubidium clock that needs to be calibrated is in the computer room of the foreign operator, it is almost an impossible task. Whether it is done at home or abroad, such maintenance operations will cost the operator or equipment provider a high cost; and require high The participation of technical personnel makes this maintenance task a task that can only be completed by specific personnel, and cannot be maintained in a timely and convenient manner
