Densham and Associates recently completed a
GMDSS upgrade to the Government marine radio station in Mauritius.
The upgrade provided 2 new 1000 watt transmitters, 11 new receivers and a duplicated Digital Selective Calling (DSC) system. The radio systems were supplied by Barrett Communications and the DSC system by TransOceana .
The majority of the equipment and a new operator console were installed in the main operations centre at Port Louis.
One of the transmitters was installed at
a remote site on the other side of the Island.
The receivers were installed in a rack at the control centre. 7 receivers are dedicated to DSC (6 operational and a hot spare) and 4 receivers are for radiotelephone.
Receiver rack
From the top: patch panel, receiver multi-couplers, DSC receivers (with local control heads) and radiotelephone receivers (with remote control heads). A power supply is provided for each receiver.
The radiotelephone receivers, the transmitter controllers and the DSC system were installed in the operator console.
