Galleon Systems has a range of devices able to synchronise PC's and computer networks with an Atomic Clock radio or gps signal reference. Products range from a small MSF, WWVB, DCF or GPS receiver that synchronises PC's via a serial connection with software drivers to synchronise the PC system time. Also available are dedicated rackmountable NTP time servers that sit directly on an ethernet network and utilise NTP to synchronise network time clients.
Radio solutions utilise either the MSF, WWVB and DCF radio time signals transmitted from UK, US and Germany respectively. A GPS solution is also available that provides an high precision timing reference for world-wide operation.
