Also, when you say "the GPS temperature," what, exactly, are you 
measuring/reporting?  Is the GPS's own time base varying with 
temperature?**  And how much thermal isolation is there between the 
various subsystems (GPS, PLL circuitry, OCXO, etc.) in your test setup?

Some photos of the test setup could be helpful.

Best regards,


**  I'm assuming that the GPS does not use the OCXO output for its 
own timing.  That is such a good idea, I can't understand why more 
designers don't do it.
