Only if you have a good antenna and/or antenna location.
I have several low cost GPS units located in far-from-ideal locations. They
work most of the time but often fade out for minutes at a time.
[This is a poor setup for using the output of a GPSDO to feed other measuring
setups, but it's great for finding corner cases in things like ntpd.]
