C.12 What is the time delivered by a GPS receiver?


Navstar GPS (global positioning system) is a satellite based
navigation system operated by the US Air Force. The signals broadcast
by GPS satellites, contain all information required by a GPS receiver
in order to determine both UTC and TIA highly accurately.  Commercial
GPS receivers can provide a time reference that is closer than 340 ns
to UTC(USNO) in 90% of all measurements, classified military versions
are even better.
