Page 4: Content Of The Usb Stick
Content of the USB stick Besides this manual, the provided USB stick includes a setup program for the monitor software GPSMON32. This utility can be used to configure Meinberg GPS receivers via their serial ports and display status information of the module. -
Page 5: General Information
General information The module GPSGEN1575/MP was designed to reconvert the intermediate frequency of 35.42 MHz transmitted on the antenna cable of Meinberg GPS clocks into the original GPS frequency of 1575.42 MHz. This technology allows the connection of GPS receivers of other manufacturers working without IF-technique to a Meinberg antenna with up to 300 meters of coaxial cable RG58 without the need of an additional amplifier. -
Page 6: The Modular System Gpsgen1575/Mp
The modular system GPSGEN1575/MP The modular system is a set of equipment composed of a GPS-signal converter GPSGEN1575, a GPS antenna diplexer GPSAV4 and a power supply unit T60B, installed in a metal desktop case (19'', 1U) and ready to operate. The interfaces provided by GPSGEN1575 are accessible via connectors in the front or rear panel of the case. -
Page 7: Features Gpsgen1575/Mp
The integrated eurocard GPSGEN1575 includes a complete GPS receiver and a signal conditioning circuit for reconversion of the IF frequency (35.42MHz) trans- mitted on the antenna cable of Meinberg GPS clocks into the original GPS frequency (1575.42MHz). The receiver circuit of the board is connected to the antenna/converter unit by a 50 Ω... -
Page 8: Gps Outputs
GPSGEN1575 uses two different paths to process the incoming signal of the antenna/ converter unit. One receive section works as a standard GPS receiver, the other is used to reconvert the IF-frequency of a Meinberg antenna/converter into the original GPS frequency band with a RF of 1575.42 MHz. -
Page 9: Enabling Of Outputs
Enabling of outputs In the default mode of operation the pulse output (PPS) and the serial interfaces are disabled until the receiver has synchronized after power-up. However, with the help of the monitor program GPSMON32 the system can be configured to enable those outputs immediately after power-up. -
Page 10: Installation
Installation Power supply The type of power supply needed for operation of GPSGEN1575/MP can be found in the chapter „Technical data power supply“ at the end of this manual. Mounting the antenna The GPS satellites are not stationary but circle round the globe in a period of about 12 hours. -

Page 12: Powering Up The System
Powering up the system If both the antenna and the power supply have been connected the system is ready to operate. About 10 seconds after power-up the receiver´s TCXO has warmed up and operates with the required accuracy. If the receiver finds valid almanac and epheme- ris data in its battery buffered memory and the receiver´s position has not changed significantly since its last operation the receiver can find out which satellites are in view now. -

LEDs in the front panel 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. -
