Is the gps date calendar specific to gps?


Asked by Zariah McDowell on Dec 04, 2021 FAQ



This calendar presents dates specific to the GPS community. The data for each day are as follows:
Accordingly,
GPS time is the atomic time scale maintained by GPS satellites and the ground control stations used to synchronize the GPS system. The time scale is a count of the number of weeks, and seconds of the current week, since an epoch. The start epoch was 0 hours (midnight) Sunday 6-Jan-1980, when GPS time was 0.
Also, GPS Time is a uniformly counting time scale beginning at the 1/5/1980 to 1/6/1980 midnight. January 6, 1980 is a Sunday. GPS Time counts in weeks and seconds of a week from this instant. The weeks begin at the Saturday/Sunday transition. The days of the week are numbered, with Sunday being 0, 1 Monday, etc.
One may also ask,
Both tick in SI seconds. The difference between GPS time and UTC time increases with each (intercalary) leap second. To find the correct UTC time, you need to know the number of leap seconds occurred before the given GPS time: where leap_count (date) is the number of leap seconds introduced before the given date.
Just so,
In general this does not come up for the casual user. The GPS message contains information that allows a receiver to convert GPS Time into Universal Time (really UTC or Universal Time Coordinated) or any time zone. Universal Time used to be called Greenwich Mean Time or Zulu time.
