Using GPS For NTP Server Time Synchronisation
The protocol also provides additional information such as visible satellites and satellite orientation in the sky.NTP servers utilise a specific receiver tailored for timing applications. Timing receivers have additional functions and circuitry to ensure a highly precise reference time. They also perform an automated site-survey to compare satellite clocks for synchronicity. Time servers also utilise an accurate pulse per second (PPS) output generated by the receiver. A PPS output provides a highly accurate reference trigger for timing purposes.The GPS system provides an ideal solution for computer network timing applications. Using the 'free-to-air' system, NTP time servers can synchronise to within a few microseconds of UTC.About the Author:Dave Evans has written a number of articles on time server and network timing.
