GPS首次授时开始的时间“0”为1980年1月6日午夜(00:00:00)(UTC时间):当年GPS时间与UTC时间正好重合,由于对UTC时间进行了修正,今天相差18秒 (到 2016 年 12 月 31 日为 17 秒,到 2015 年 6 月 30 日为 16 秒),与 GPS 时间相比的秒数,如上所述,不受任何天文调整。从 GPS 接...
GPS 系统中有两种时间区分,一为UTCTime,另一为LocalTime 本地时间(LocalTime):也就是系统设置时区的当前时间。比如系统的右下角显示的时间为“2017/8/18 11:47”,那么这个时间就是当前系统的本地时间! 格林威治时间(UTCTime):就是0时区的时间,本初子午线被定义为通过格林威治经线的位置,相对这条经线的时区向...
Standard of time definition: UTC, GPS, LORAN and TAI A lot of the current technology to work properly requires a very precise definition of the time. Typically this time is maintained by specific atomic clocks and has a satellite distribution.There are many standard definitions of the time, bu...
time_t记录了Unix时间,即纪元至某一时刻经过的秒数。 而tm结构体则记录了年份、月数、日期、小时、分钟、秒、是否考虑daylight saving。 当用gmtime函数将tm结构体转为time_t时,tm结构体时间被认为是UTC时间。 当使用localtime函数时,tm结构体时间被认为是UTC时间提前或推迟一段时间,即当地时间,时区信息则从TZ环...
UTC and GPS: Though both are used for time synchronization, they are not the same, and there is a constant offset of +18sec between them.
I want to know the difference between the UTC, TAI, and GPS timebases, their relationships to each other, as well as how to convert them from one to another. SolutionInternational Atomic Time (TAI)TAI time is maintained by the Bureau International des Poids et Mesures (BIPM). TAI time ...
GPS, Global Positioning System time, is the atomic time scale implemented by the atomic clocks in the GPS ground control stations and the GPS satellites themselves. GPS time was zero at 0h 6-Jan-1980 and since it is not perturbed by leap seconds GPS is now ahead of UTC by18 seconds. ...

UTC是英文Coordinated Universal Time的缩写,即协调世界时。它是一种标准的时间制度,用来统一全球时间的标准。UTC可以简单地理解为是一个基于原子钟的全球标准时间,它与格林尼治标准时间(GMT)相同。目前UTC已成为全球通用的时间标准,也是世界各国通信、交通、科学、高新技术、能源等领域进行国际技术合作的...
