4 The Modular System LANTIME
4 The Modular System LANTIME
The basic-system M1000-S is a set of equipment, composed of a reference clock (e.g.: GNSS satellite controlled
clock, long wave radio clock or IRIG/AFNOR time code reader), a single-board computer SBC LX800 500 MHz
with integrated network card and a power supply unit, all installed in a metal desktop case and ready to operate.
The implemented NTPD distributes the reference time from the used receiver cyclic in the network. Infor-
mation on the NTPD can be monitored via the network.
The installation of a LANTIME Server is very easy for the system/network administrator. The network ad-
dress, the netmask and the default gateway have to be configured (see chapter "Sarting of Operation"). 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 a large display which is accessed via network connection (e.g. VP100/20/NET).
In order to avoid a service interruption several LANTIME NTP servers can be installed in the same network to
obtain redundancy.
IMS-M1000-S Date: 6th September 2017 7

5 Network Timeserver with GNSS 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 ref-
erence. The several LANTIME variants differ from each other by the time reference and output configuration.
A GNSS receiver (GPS, GLONASS, Galileo or BeiDou), 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 GNSS 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 protec-
tion: IP55). However, we recommend an indoor installation, as close as possible to the wall where the antenna
cable is entering, to minimize the risk of overvoltage damage, for example by lightning.

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.

6.3 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-S Date: 6th September 2017 11

7 Booting the GNSS 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 (38400/8N1/VT100)
HTTP Interface
Secure HTTP Interface (HTTPS)
SNMP Management
A startup wizard is available for the initial operation of the LANTIME. Once a connection to the system has been
established with an SSH session (network) or via the LANTIME serial interface, this command-line based tool
can be used for initial configuration (see also chapter "LANTIME S-Chassis: Putting in Operation"). 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

10 The graphical user interfaces
10 The graphical user interfaces
The LANTIME offers two different options for configuration and status management: An extensive and powerful
web interface and SNMP. In order to use the SNMP features of your LANTIME, you need special software
like management systems or SNMP clients. In order to use the web interface, all you need is a web browser
(LANTIME supports a broad range of browsers, we recommend Mozilla Firefox).
The WEB Interface
The web interface can be used by more than one user in parallel, but the two or more running sessions may
influence each other. We explicitly do not recommend the parallel usage of the configuration interfaces.
Connect to the web interface by entering the following address into the address field of your web browser:
http://198.168.10.10 (You need to replace 198.168.10.10 with the IP address of your LANTIME).
