GPS relies on very accurate timing of it's signals.  Each satellite
carries an atomic clock [Rubidium?] and the frequency of the satellite's
various signals are thus extremely accurate and stable.  With
appropriate equipment, they can be used to control a standard oscillator
which in turn controls the TXCO in the K3 to the same accuracy.  The K2,
K1, and KX1 have no such provision.
