Design And Realization Of The Atomic Clock Performance Analysis Platform Software

At present, the Time and Frequency System of high accuracy which contains many atomic clocks builds and keeps a time scale according some algorithm. And the atomic clock has to be in a good state. The Atomic Clock Performance Analysis Platform Software is a tool of evaluating the run-state of clocks. And it is one important part of the Atomic Clock Time and Frequency System, and is also the preparing work of the Integrating Atomic Time Calculation. By developing the platform software, this paper did some work as follows:This article discussed the token of frequency variable deeply, and gave the formula of frequency accuracy, frequency drift rate, frequency stability, clock speed and clock acceleration, and the function of the time model. Then it also analyzed the relationship of clock speed and frequency accuracy, clock acceleration and frequency drift rate. These are the theory preparing work for the Design and Realization of the Atomic Clock Performance Analysis Platform.Using the theory of Gross Error Inspecting which is always used in the theory of Survey Adjustment to deal with the datum of time and frequency, constructing the error inspecting estimation of clock difference datum, gross error could be easily found and deleted.This paper calculated the applied formula of frequency accuracy, frequency drift rate, frequency stability, and analyzed the atomic noise model in the time domain, and then gave the calculating method of the model's modulus.According to the demand of the performance analysis platform, this article detailedly designed the five main functions of the atomic clock performance analysis platform: datum query analysis, clock performance variable calculation, clock performance evaluation, results query analysis, and datum input and output function. And it also gave the project in detail.The writer developed the Atomic Clock Performance Analysis Platform Software independently, and realized the aim of software. This paper introduced the developing environment, tools, and developing process of the platform software, and also introduce the software interface, analyzed the output results of the software.At last, the whole research work was summarized, and the next work was also showed.
