The NR3623 CAL 10MHz frequency reference which features Auto-Cal, continously monitors the correction coefficients being applied to the OCXO to compensate for aging and temperature stability. The coefficients are stored in non-volatile memory and in the event of GPS loss are used to maintain the accuracy of the crystal.  Frequency loss offset +-10 ppb..  A good choice for general lab use, Simulcast and test systems.
