A High Precise GPS/GLONASS Synchronization Clock PLL
Liu Chun-ping · Telecommunication Engineering · 2002
A clock synchronization implementation which can be used in mobile system is presented in this paper. The exterior synchronization resource is the signal receivd from GPS/GLONASS. The CPU reads the phase error data of the digital distinguisher and adjusts the input voltage of OCXO in this wayfrom a small step to a big step. As a result, a very high synchronization precision is achieved.
