• TimeTools T550 time server is a very accurate, Stratum-1 Multi-GNSS referenced Network Time Protocol Server in a 1U rack-mountable enclosure. The built-in 32 channel timing receiver provides concurrent multi-constellation reception of GPS and either GLONASS, BeiDou or Galileo for improved reliability and redundancy.
  The T550 also features Dual Ethernet ports and a high-stability TCXO oscillator, which provides extended Stratum-1 holdover during loss of GNSS signal lock.
  The T550 provides an accurate time reference to computer networks of any size and can accurately synchronize any NTP or SNTP compatible system.
