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.]
