> What if the crystal driving the DSP changes frequency with temperature?
I believe it would have no effect. The local clock should drop out of any navigation or timing solution, so long as the changes are slow enough to avoid loss of lock in carrier tracking. Let's take a GPS module with 1 PPS output. Over temperature its internal TCXO might be wandering around by parts in 10^7. Does this hurt the 1 PPS? Nope, it soldiers on, the pulses remaining accurately spaced by 1 second despite the variation in the local clock.
