WebThe NTP100-GPS is an NTP (Network Time Protocol) server that synchronizes to GPS satellites and distributes NTP reference signals via Ethernet. When synchronized to the atomic clocks in GPS and GLONASS satellites, the long term accuracy of the device is the same as the atomic clock of the GNSS. Web8 nov. 2024 · First, at the topmost level, there is highly accurate time resources’ ex. atomic or GPS clocks. These clock resources are called stratum 0 servers, and they are linked to the below NTP server called Stratum 1,2 or 3 and so on. These servers then provide the accurate date and time so that communicating hosts are synced to each other.
