The SRS PRS10 has a very versatile PPS input that can discipline its 
frequency with a truly comprehensive array of adjustments (to the 
point of potential bafflement).  The PRS10 and a good PPS source can 
make an excellent GPSDO.  (Note that the PRS10 is, by itself, one of 
the best compact Rb oscillators available.)

The PRS10 manual has a good explanation of the PPS operation at 
pp.14-17 and 33-36:
