The ES-185F/NTP6 is a GPS Master Clock/Time Code Generator/NTP Time Server. The unit receives accurate time and date information from Global Positioning System satellites and supplies this data to the user in a variety of forms. A 12-channel receiver is employed that is capable of tracking up to twelve satellites simultaneously, although reception of only one is required for time data to be output. ESE's ES-185F/NTP6 offers an accuracy of better than 10nS and is entirely self-setting. The unit provides an internal Coin Cell for backing up the GPS receiver time.
