GPS is extremely complicated and studying it is probably not worth your while if you're only trying to modulate a time signal onto an RF carrier. For that, look at basic RF digital modulation techniques. Are you trying to get microsecond accuracy? Sub-millisecond? Sub-second? It gets easier at coarser levels. You stop having to account for speed of light delay between the transmitter and receiver, relativistic corrections because of the endpoints being in motion, etc.
