The Galleon NTS-4000-GPS-R is a Stratum 1 standalone NTP time server that delivers primary reference timing via GPS to TCP/IP networks. The unit combines a 12-channel active GPS antenna with a dedicated solid-state computer running a proprietary secure operating system, synchronizing network time to better than 1 microsecond relative to UTC. It occupies a single 19-inch rack unit (1U) and connects via standard 10/100 MBit Ethernet, handling over 3,000 NTP requests per minute for small to medium-sized deployments.
