See this link which describes picosecond laser timing for ranging of satellites to the mm. Not sure how this would affect sychronization though.

Can anyone shed some light as to why is important to a achieve picosecond time synchronization?
For this third technical element, Rockwell Collins is tasked with developing multifunction communication system solutions that yield DARPA STOIC objective picosecond-accurate time transfer and enable GPS-levels of relative positioning accuracy in contested environments.
