GPS / GNSS NTP Time Servers

VCL offers a very wide range of NTP Time Servers that are designed to provide NTP Time and ITU-T G.811 Primary Reference Clock that is locked to a GPS / GNSS reference to provide time synchronization to private networks such as Railways and Metro (ticketing and platform) networks, Airports and Air-Traffic Control facilities, Electric Sub-Stations, Power Distribution and Transmission companies, Oil and Gas Utilities, ISPs and Cable TV networks as well as to Campus networks that are required to maintain a complete isolation from public networks for security reasons. It may be also used by 2G, 3G, 4G and 5G service providers which provide a ToD (Time-of-Day) reference to their customers over their wireless networks.
