Non-timing receivers could be unsuitable for your requirements, as
some of us have discovered:

=======================
Gabs,
The oscillations I reported are not due to the use of a navigation GPS
receiver. I have discovered one other difference between the two Raspberry
Pi PCs - firmware version. I upgraded the PC with the oscillation from
version 337601 to version 346337 firmware and this appears to have resolved
the issue. Fingers crossed! Once things have stabilised, you will find a
comparison between navigation (RasPi #1, MTK3339 Adafruit) and timing (RasPi
#2, Trimble Resolution SMT) receivers here:
