GPS sync has nothing to do really with different radios having different latency or jitter, and has everything to do with frame size and timing (although different frame sizes can have different latency).
See THIS forum post on how GPS sync works. NOTE although it's written for ePMP, the underlying theory applies to all radios that use TDD sync.
