1. DESCRIPTION
1.1. The GPD2000C01
The GPD2000C01 module is a GNSS signal distributor from one input to four outputs
that provides a 20dB gain between the input and any of the outputs in order to
compensate the attenuation introduced by the cable through which the signal is
received from the antenna.
The module has a high enough bandwidth to distribute all of the global navigation
satellite system (GNSS) frequency bands. These systems use the L Band and their
frequencies range from 1.1 to 1.6GHz.
GNSS signals use active antennas and usually require a power supply voltage of 3.3V or
5V to operate. This voltage is provided through the same coaxial cable that is used to
receive the GNSS signal.
The voltage used to power the antenna can come from an internal power supply to the
GPD2000C01 module or from one of the GNSS receivers the GPD2000C01 has connected
to the outputs labeled RX1+DC and RX2+DC. The power supply used at any given
moment is the one with the highest voltage and the three power supplies are redundant
such that as long as one of them is valid the antenna remains powered.
It is possible to monitor the GPD2000C01 status remotely using a communications
controller module installed in the same mounting frame. In addition, certain controller
modules provide SNMP management and the ability to record events in a file including
date and time information for further analysis.
The GPD2000C01 is a TL2000 terminal line module and can be housed in a two rack unit
(2 RU) UR2000 mounting frame.
