4 The Modular System LANTIME
4 The Modular System LANTIME
LANTIME is a set of equipment composed of a reference clock GPS180, a single-board computer SBC ELX800
500 MHz with integrated network card, and a power supply unit, all installed in a metal desktop case and ready
to operate. The interfaces provided by LANTIME are accessible via connectors in the rear panel of the case.
Details of the components are described below.
The implemented NTPD distributes the reference time from the GPS180 receiver cyclic in the network. Infor-
mation on the NTPD is monitored on the LC-Display or can be inquired via the network.
The installation of LANTIME is very easy for the system/network administrator. The network address, the
netmask and the default gateway have to be configured from the front panel of LANTIME. The network address
or the equivalent name of LANTIME has to be shown to all NTP clients in the TCP/IP network.
As well as NTP the Linux system also supports a number of further network protocols: HTTP(S), FTP, SSH
and Telnet. Because of this remote configuration or status requests can come from any WEB browser. This
access via the network can be deactivated. Changes in the receiver status, errors or other important events are
logged either on the local Linux system or on an external SYSLOG-Server. In addition messages can be sent to
a data center via SNMP traps or automatically generated e-mails where they can be recorded. Furthermore all
alarm messages can be displayed by the large display VP100/20/NET that is accessed via network connection.
In order to avoid a service interruption several LANTIME NTP servers can be installed in the same network to
obtain redundancy.

5 Network Timeserver with GPS synchronized
time base
The LANTIME (Local Area Network Time Server) provides a high precision time base to a TCP/IP network
(Stratum-1-Server). The NTP (Network Time Protocol) is used to synchronize all NTP clients with the refer-
ence. The several LANTIME variants differ from each other by the time reference and output configuration. A
GPS or combined GPS/GLONASS receiver, a long wave receiver (like DCF77, MSF or WWVB) or an IRIG time
code receiver can be integrated as an internal reference as well as a combination of these references (hybrid
system). External references are also possible.
The LANTIME system is a set of equipment composed of a internal receiver, a single-board computer and
a power supply, all installed in a metal 19 inch modular chassis and ready to operate. A simplified LINUX
operating system is installed on the single-board computers flash disk. Eight push buttons and a display can
be used to configure and monitor the time server.
After the network connection has been established the time server can also be configured and monitored
remotely from a workstation via TELNET or FTP. An integrated web server enables access to the LANTIME by
using an ordinary web browser.

6 Mounting the GPS Antenna
6 Mounting the GPS Antenna
The GPS satellites are not stationary, but circle round the globe with a period of about 12 hours. They can only
be received if no building is in the line-of-sight from the antenna to the satellite, so the antenna/downconverter
unit must be installed in a location that has as clear a view of the sky as possible. The best reception is
achieved when the antenna has a free view of 8◦angular elevation above the horizon. If this is not possible, the
antenna should be installed with the clearest free view to the equator, because the satellite orbits are located
between latitudes 55◦North and 55◦South. If this is not possible, you may experience difficulty receiving the
four satellites necessary to complete the receiver’s position solution.
The antenna/converter unit can be mounted on a wall, or on a pole up to 60 mm in diameter. A 50 cm
plastic tube, two wall-mount brackets, and clamps for pole mounting are included. A standard RG58 coaxial
cable should be used to connect the antenna/downconverter unit to the receiver. The maximum length of cable
between antenna and receiver depends on the attenuation factor of the coaxial cable.
Up to four GPS180 receivers can be run with one antenna/downconverter unit by using an optional antenna
splitter. The total length of an antenna line from antenna to receiver must not be longer than the max. length
shown in the table below. The position of the splitter in the antenna line does not matter.
The optional delivered MBG S-PRO protection kit can also be used for outdoor installation (degree of pro-
tection: IP55). However, we recommend an indoor installation, as short as possible after wall entering of the
antenna cable, to minimize the risk of overvoltage damage by lightning for example.
6.1 Example:
Type of cable diameter Ø Attenuation at 100MHz max lenght.
[mm] [dB]/100m [m]
RG58/CU 5mm 17 300 (1)
RG213 10.5mm 7 700 (1)
(1)This specifications are made for antenna/converter units produced after January, 2005
The values are typically ones; the exact ones are to find out from the data sheet of the used cable
IMS-M1000 Date: 9th June 2016 9

6.2 Antenna Assembly with Surge Voltage Protection
Optional a surge voltage protector for coaxial lines is available. The shield has to be connected to earth as
short as possible by using the included mounting bracket. Normally you connect the antenna converter directly
with the antenna cable to the system.

6 Mounting the GPS Antenna
6.3 Antenna Short-Circuit
(systems with front display only)
In case of an antenna line short-circuit the following message appears in the display:
ANTENNA
SHORT-CIRCUIT
DISCONNECT POWER
! ! !
If this message appears the clock has to be disconnected from the mains and the defect eliminated. After that
the clock can be powered-up again. The antenna supply voltage must be 15VDC .
IMS-M1000 Date: 9th June 2016 11

7 Booting the GPS180 receiver
If both the antenna and the power supply have been connected, the system is ready to operate. About 2 minutes
after power-up the receiver’s oscillator has warmed up and operates with the required accuracy. If the receiver
finds valid almanac and ephemeris data in its battery buffered memory and the receiver’s position has not
changed significantly since its last operation, the receiver can determine which satellites are presently in view.
Only a single satellite must be received to synchronize and generate output pulses, so synchronization can be
achieved within one minute after power-up.
If the receiver position has changed by more than one hundred kilometers since last operation, the satel-
lites’ real elevation and Doppler might not match those values expected by the receiver, and this will force the
receiver to start scanning for satellites. This mode is called Warm Boot because the receiver can obtain ID
numbers of existing satellites from the valid almanac. When the receiver has found four satellites in view it can
update its new position and switch to Normal Operation. If the almanac has been lost (because the battery
has been disconnected) the receiver has to scan for a satellite and read in the current almanac. This mode is
called Cold Boot. It takes 12 minutes until the new almanac is complete and the system switches to Warm Boot
mode, scanning for other satellites.

8 Booting the Single Board Computer
8 Booting the Single Board Computer
The LINUX operating system is loaded from a packed file on the flash disk of the single board computer to a
RAM disk. All files of the flash disk are stored in the RAM disk after booting. This guarantees that the file
system is in a defined condition after restart. This boot process takes approximately two minutes. During this
time the following message appears on the display:
NORMAL OPERATION
NTP: not sync
Thu, 01.01.2008
UTC 12:00:00
NORMAL OPERATION
NTP:sync to local
Thu, 01.01.2008
UTC 12:00:00
After starting the LINUX system, the network function is initiated and the communication program with the
receiver and the NTPD (NTP daemon) is started. Then NTPD starts synchronization with the reference clocks
(usually the hardware clock of the single board computer and the integrated receiver clock). The message "NTP:
sync to local" is displayed until synchronization is complete.
For the synchronization of the NTPD with the time reference it is necessary that the receiver is synchronous
with the incoming time signal. In this case the following message is monitored on the display:
NORMAL OPERATION
NTP: Offs. 2ms
Thu, 01.01.2008
UTC 12:00:00
The second line shows the user that the NTPD is synchronized with the receiver with an offset of 2ms (Figure).
Because of the internal time of the NTP which is adjusted by a software PLL (phase locked loop) it takes a
certain time to optimise this offset. The NTPD tries to keep the offset below +-128 ms; if the offset becomes
too large, the system time is set with the receiver’s time. Typically values for the offset are +-5 ms after the
NTPD has already synchronized.

9 Configuration User Interface
There are several ways to configure the LANTIME parameters:
Command Line Interface (CLI) via TELNET
Command Line Interface via SSH
Command Line Interface via serial terminal in front panel
(38400/8N1/VT100)
HTTP Interface
Secure HTTP Interface (HTTPS)
Front panel LCD/VFD Interface (except LANTIME M100)
SNMP Management
In order to be able to configure the time server via the web interface or a telnet/SSH connection, an IP address
has to be assigned via the front panel keys and LC/VF display (for automatic assignment possibilities please
refer to: DHCP IPv4 or AUTOCONF IPv6). LANTIME variants without a display can be configured using the
serial terminal interface (labeled “Term” or “Terminal”) The termin program should be set to 38400Baud / 8N1
– VT100 emulation. Once the IPv4 address, net mask and IPv4 GATEWAY have been set up or the network
interface has been automatically configured with DHCP/Autoconf, further configuration changes can be done
via a network connection:
To set up a TELNET connection the following commands are entered (replace 198.168.10.10 with the IP of
your LANTIME):
telnet 198.168.10.10 // LANTIME IP address
user: root
password: timeserver
With “setup” the configuration program is started.
To set up a SSH connection the following commands are entered:
ssh [email protected] // LANTIME IP address
password: timeserver
With “setup” the configuration program is started.
To set up a HTTP connection the following address is to enter in a web browser:
http://198.168.10.10 // LANTIME IP address
password: timeserver
To set up a Secure HTTP (HTTPS) connection the following address is entered in a web browser:
https://198.168.10.10 // LANTIME IP address
password: timeserver
