Rockwell Chipset GPS receiver is mounted with ZODIAC protocol output and 1PPS 1sec pulse output.
GPS receiver has capability to receive signals from 12 satellites. For 300ns accuracy it is needed only 5 sats. This 12-channel architecture provides rapid Time to First Fix under all startup conditions. Enhanced built in algorithm provide superior performance in "urban canyon" and dense foliage environments.
Time stamps in the server are connected through the GPS system to UTC world time.

With NTP server GPS active antenna is delivered also.
