3 Global Information LANTIME M400/GPS
LANTIME stands for Local Area Network Timeserver. The LANTIME provides an absolute and highly precise
time reference in a TCP/IP network (stratum 1 server). The time is made available to all NTP clients by NTP
protocol (Network Time Protocol) and allows a simple integration of an absolute time reference into an existing
network.
The individual LANTIME variants differ mainly in the reference time used: An external radio clock, a built-in
GPS or GNSS (GPS, GLONASS, Galileo, BeiDou) satellite receiver / GNS-UC (only GPS and Galileo), an
IRIG time code receiver or a long wave receiver (DCF77, MSF, WWVB), as well as external NTP servers or
a DCF77/GNSS combination as hybrid receiver can be used as reference time source. A GNSS synchronized
LANTIME consists of a GNSS satellite receiver, a single board computer with integrated network card and a
power supply.
A simplified LINUX operating system is implemented on the single-board computer, which is loaded from a
flash disk during the boot phase. All settings can be made using eight pushbuttons and a display. There is
also the possibility of remote configuration via the network using FTP or TELNET. An integrated web server
allows access to the LANTIME with any web browser.
