Page 7: General Information
General Information The satellite receiver clock GPS167 has been designed to provide extremly precise time to its user. The clock has been developed for applications where conventional radio controlled clocks can´t meet the growing requirements in precision. High precision available 24 hours a day around the whole world is the main feature of the new system which receives its information from the satellites of the Global Posi- tioning System. -
Page 9: The Modular System Gps167Lcd-Mp
The Modular System GPS167LCD-MP GPS167LCD-MP GPS-Receiver is a set of equipment composed of a satellite control- led clock GPS167 (LQ-OCXO) together with a power supply unit Mean Well T-60B, both installed in a metal desktop case MULTIPAC and ready to operate. The inter- faces and input/output signals provided by GPS167 are accessible via connectors in the rear and the front panel of the case. -
Page 10: Pulse Outputs
COM0 is compatible with other radio remote clocks made by Meinberg. It sends Meinberg´s standard time string either once per second, once per minute or on request with ASCII ´?´ only. The interfaces can also be configured to transmit capture data either automatically when available or on request. -
Page 11: Dcf77 Emulation
DCF77 Emulation The GPS167 satellite controlled clock generates TTL level time marks (active HIGH) which are compatible with the time marks spread by the German long wave transmit- ter DCF77. This long wave transmitter installed in Mainflingen near Frankfurt/ Germany transmits the reference time of the Federal Republic of Germany: time of day, date of month and day of week in BCD coded second pulses. -
Page 12: Installation
Installation Mounting the Antenna The GPS satellites are not stationary but circle round the globe in 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/converter unit must be installed in a location from which as much of the sky as possible can be seen. -

Page 14: Antenna Short-Circuit
Antenna Short-Circuit 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 is to eliminate. After that the clock can be powered-up again. The antenna supply voltage must be in a range of 18.5V (free) and 17V (connected GPS antenna). -
Page 15: The Front Panel Layout
The Front Panel Layout FAIL LED The FAIL LED is turned on whenever the TIME_SYN output is low (receiver is not synchronized). LOCK LED The LOCK LED is turned on when after power-up the receiver has acquired at least four satellites and has computed its position. In normal operation the receiver position is updated continuously as long as at least four satellites can be received. -
Page 16: Next Key
At the end of the two lines the day of the week, the current date, the name of the time zone (as defined in the setup menu) and local time is displayed. If the NEXT key is pressed from the root menu a submenu is displayed showing the receiver´s software revision: Meinberg GPS167 S/N: 100XXX20 REV:4.30 ED167... -
Page 17: Menu Receiver Pos
Menu RECEIVER POS. This menu shows the current receiver position. The NEXT key lets the user select one of three formats. The default format is geographic latitude, longitude and altitude with latitude and longitude displayed in degrees, minutes and seconds. The next format is geographic, too, with latitude and longitude displayed in degrees with fractions of degrees. -
Page 18: Menu Sv Position
Menu SV POSITION This menu gives information on the currently selected satellite (SV). The satellite´s ID number, its elevation, azimuth and distance from the receiver position reflect the satellite´s position in the sky whereas the doppler shows whether the satellite is coming up from the horizon (doppler positive) or going down to the horizon (doppler negative). -
Page 19: Menu Setup
Menu SETUP From this menu, several topics can be selected which let the user edit parameters or force special modes of operation. A specific topic can be selected using the NEXT key. Depending on the current topic, pressing the CLR/ACK key either enters edit mode with the selected set of parameters or switches to the selected mode of operation (after the user has acknowledged his decision). -
Page 20: Setup Time Zone
SETUP TIME ZONE This menu lets the user enter the names of the local time zone with daylight saving disabled and enabled, together with the zones´ time offsets from UTC. The left part of the display shows the zone and offset if daylight saving is off whereas the right part shows name and offset if daylight saving is on. - Page 21 SETUP: DAYLIGHT SAV OFF DAYLIGHT SAV OFF Date: 25.10.**** Day Of Week: SUN Time: 3:00:00 If no changeover in daylight saving is wanted, an identical date and time must be configured in both of the submenus (see fig. below). In addition identical offsets for DAYLIGHT SAV ON/OFF should be configured in the submenu TIMEZONE.

Page 23: Setup Serial String Mode
The following time strings can be selected: Meinberg Standard String GPS167 Capture String SAT String UNI-Erlangen String NMEA String (RMC) SPA String COMPUTIME String Refer to chapter Time Strings for details. SETUP SERIAL STRING MODE This menu lets the user select the serial ports´ mode of operation. The possible modes depends on the selected output string. -
Page 24: Setup Initial Position
SETUP INITIAL POSITION When the receiver is primarily installed at a new location far away from the last position saved in the receiver´s memory the satellites in view and their dopplers will differ so much from those expected due to the wrong position that GPS167 has to scan for satellites in Warm Boot mode. -
Page 25: Init Gps Parms
INIT GPS PARMS This menu lets the user initialize all GPS datas, i.e. all saved satellite datas will be cleared. The user has to acknowledge this menu again before the initialisation starts. The system starts operating in the COLD BOOT mode and seeks for a satellite to read its actual parameters. -
Page 26: Antenna Cable
ANTENNA CABLE This menu asks the user to enter the length of the antenna cable. The received time frame is delayed by approx. 5ns per meter antenna cable. The receiver is able to compensate this delay if the exact cable length is given. The default value is 20m. The maximum value that can be entered is 500m (only with low loss cable). -
Page 27: Firmware Updates
Firmware Updates Whenever the on-board software must be upgraded or modified, the new firmware can be downloaded to the internal flash memory via the serial port COM0. There is no need to open the metal case and insert a new EPROM. If the MENU key on the front panel is pressed while the system is powered up, a bootstrap-loader is actived and waits for instructions from the serial port COM0. -
