Hi all,
A leap second insertion occurred on December 31, 2016. What does this means to reach users? Not sure, but here is all the info below.
just fyi…
If I understand correctly, these are factored into the clock corrections that the ground segment stations send to to the Space Vehicles, which I think will process them and include them in the clock corrections sent in the NAV message. For GPS at least… So our GPS time can apply the necessary corrections to the time at the SV? Unless it is our receiver clocks that need to be adjusted?
