| Abstract: | A technical method was proposed to detect the stability of the computer internal clock with the use of GPS.A set of testing method is established.A group of experimental program is set up.The test lasted for 117 days.Processing and analyzing the experimental data,we obtained a set of results which can objectively reflect the long-term stability.The result analysis showed that: with the use of the first-order polynomial,it fitted that the clock speed of the experimental computer is 0.01,its accuracy is 0.000... |
