Embodiment 1
[0034] The inventive method comprises following two processes:
[0035] 1. Input the atomic time and leap second forecast, and output the correct UTC time;
[0036] 2. Input UTC time and leap second forecast, and output correct atomic time.
[0037] Among them, the input is atomic time and leap second forecast, and the output is coordinated universal time. The process includes the following steps:
[0038] ① Obtain the leap second forecast from the satellite navigation message. The leap second forecast includes the current time difference between UTC and atomic time, the future time difference between UTC and atomic time, and the absolute second of UTC. It should be noted that since the leap second forecast is calibrated by the UTC time system, and the input atomic information is calibrated by the atomic time system, the two time systems use different reference systems, so the two systems need to be calibrated For information conversion, the time correspondence between the t...
Embodiment 2
[0054] This embodiment mainly adds the following special processing steps in the process step ⑤ in which the input of embodiment 1 is the atomic time and the leap second forecast, and the output is the coordinated universal time: that is, if the current moment is the occurrence of the leap second, the output will appear In the case of 60 seconds in UTC, special processing is required at this time, that is, output 60 seconds before the leap second occurs, that is, set 60 to the second of the obtained Coordinated Universal Standard Time, so as to obtain the correct leap second time Coordinated Universal Time standard time.
[0055] Other technical characteristics are identical with embodiment 1.
Embodiment 3
[0057] This embodiment mainly adds the following special processing steps in the process step v) in which the input of embodiment 1 is Coordinated Universal Time and leap second forecast, and the output is atomic time: that is, if the current moment is neither before the leap second occurs, nor If it is not after a leap second occurs, that is, when a positive leap second occurs, and 60 seconds in UTC is entered, it is necessary to judge whether the second in UTC is 60; if the second in UTC is 60, the UTC absolute Seconds plus the current time difference between UTC and atomic time to get the absolute second of atomic time; if the second of UTC standard time is not 60, add the absolute second of UTC to the future time difference between UTC and atomic time to get atomic time Absolute seconds.
[0058] Other technical characteristics are identical with embodiment 1.
