GPS Clock

TimeTools manufactures and distributes GPS clock, NTP server and PC time server systems for accurate computer and network timing. GPS Clock NTP systems can be used to distribute accurate time from an external timing reference around a network. Network time clients can sync time to within a few milliseconds of the correct time. Both MSF, DCF-77 radio and GPS external time references are also available as time server solutions for PC's by utilising a standard RS232 interface.

Please take time to view our comprehensive range of NTP Server and PC time server synchronisation products and systems.

	GPS Time Server for PC's. Accurate GPS timing server for PC's and other time critical devices and applications. TimeTools GPS atomic clocks for PC's provide accuracies to <100 nanoseconds and can accurately synchronise's Windows 95/98/ NT/2000/XP/2003, LINUX and UNIX platforms.
	GPS NTP Server NTP version 4.2 stratum one GPS, radio and dual reference NTP servers for accurate IP network timing. TimeTools s5000 series Radio and GPS NTP Server provides a highly accurate, highly reliable solution to your network timing problems.

TimeTools GPS Clock Software is a freeware utility that runs on any Windows NT/2000/XP/2003 workstation or server. The software polls time from a standard NMEA GPS receiver connected to the host PC's serial port and optionally allows time to be synchronised on the host PC.

The GPS clock utility polls GPRMC messages from a standard NMEA GPS receiver. It shows information received from the GPS receiver such as time, date, GPS status, number of satellites in view, longitude and latitude information. The utility also displays NMEA sentences as they are transmitted by the GPS receiver.

The GPS clock utility can also update the system time of the host PC with GPS time. Note however, time synchronisation can only be achieved to the nearest second. Standard NMEA GPS devices do not have a pulse per second output that can be utilised by the serial port of a PC. Therefore, the microsecond accuracy that is available from TimeTools GPS T1000 and T2000 GPS timing receivers is not available with this software.

To Do:

18 January 2007 : Add functionality to restrict time updates to within a 15 minute window of the current system time. This could be used as a 'safety net', incase any erroneous NTP servers provide incorrect un-synchronised time information. This could be added as a checkbox to enabled or disable time checks.
