I think a GPSDO is different from "GPS disciplining". In a GPSDO you
are disciplining a local oscillator, not a GPS system.
Algorithms used to discipline oscillators are also used and were
developed for other uses. For example it is common to use a PID to
discipline a local oscillator. The PID algorithm predates GPS by more
than a half century.
The algorithm is not complex. The hard part is selecting constants
