The Ublox modules (at least some of them) can support an external oscillator and have messages for controlling oscillator parameters and disciplining. ------------------------ > This is actually done. But you need to design the GPS receiver from the ground up to use a very high quality oscillator. The Thunderbolt is an example of this. It has a 10MHz OCXO used as the internal clock.

Interested to know if anyone has done this with a ublox receiver, I spotted the option in some of the technical documents and went as far as finding a stockist for the external DAC I think it'd need.
