Mimer SoftRadio - Marine systems
Mimer SoftRadio can be built in many sizes and for many purposes
Please also see the other pages with examples.
Below are a number of examples of systems for use in marine environment both onshore and ofshore. All of them can be expanded at any time to any size needed.
Coastal radio centre with three radio sites.
A coastal radio dispatcher mostly needs to use many radio sites in order to get coverage along a coastal line or other water way. In the example to the left there are three radios each at three different sites. This can of course be many more.
The dispatchers can listen to all radios at the same time and transmit on either one of them.
If the option GroupSend is added to the system, the operator can also transmit on several radios at the same time.
Using Receiver Voting / Diversity
In the example above three radios are connected to the system using the same radio channel, Channel 16. This can be a problem for the operator since he is likely to hear the ships on more than one receiver simoultaneusly. If one signal then is a bit noicy or distorted he will have a hard time to hear the good signal.
With the use of a diversity voting system the operator gets audio from only one receiver at a time to his speaker. The system will choose the first receiver with an acceptable signal and ignore the others.
The system can connect many receivers at different sites in this way.
Sending and receiving DSC and ATIS
A vital part of marine systems are the abilities to receive and transmit DSC calls. This can be achieved through the optional module “MarineCalls” in your SoftRadio dispatcher software.
The dispatcher can easily make a DSC call to a single ship or group of ships and with the use of SoftRadios Local CallLog the operator software will display the incoming messages with time stamps.
Calls to the operators MMSI number will be presented in green and an alarm call will be highlighted in red for higher visibility. The alarm can also be set to sound an alarm tone.
The calls are both displayed in a user window that shows the latest calls and also saved into a log file on the computer. A new log file is created for each new day.
On Central European inland waterways ATIS is used. This is a message transmitted at each PTT from the ships containing the identity of the ship. The ATIS messages are in the same format as the DCS calls and will therefor be displayed in the same log list as DSC calls.
ATIS calls can also be exported to other systems, outside SoftRadio, for example GIS systems, so that ships can be highlighted on a map when they transmit.
Radios onboard ships
SoftRadio onboard the Swedish Coast Guard ships.
Large ships have many radios onboard. To combine them into a common operator interface is often a very good idea. A touch screen PC with virtual control panels is a very intuitive way of working with different types of radios.
The example above is from the Swedish Coast Guard. More information on this system, is found on the Command and Control page.
Oil/gas rigs and Wind farms
Example from an oil rig with many types of radio systems.
Wind power farm system with different types of IP connections to the radio sistes.
On an oil or gas rig in the North Sea there are many types of radio systems. These systems can all be connected together through the use of Mimer SoftRadio. Also when building and running wind farms you have a need for many types of radio systems.
In the example above there are local operators both on the rig and on land connected via the Internet. The operators can connect to both the local radio net on the rig and to marine VHF and Airband VHF. They also have access to the PA and alarm system on the rig.
Combining this with the option CrossPatch means that an operator for example can cross connect a Tetra user on the rig with a helicopter pilot, using airband radio, approaching the rig.
Different radio types
Mimer SoftRadio connects to any radio type via audio and PTT. In this way we can remote control Sailor, Garmin or other standard types of marine VHF radios.
If you have a need for channel change, scanning on/off etc, menu driven functions, we recommend that you use one of the radios that we have virtual control heads for. For example Icom IC-M423, the Jotron 7750C or the land mobile radios Motorola GM360 or Motorola DM4600. They can all be programmed to work as any other Marine VHF radio.
HF radio stations
Mimer SoftRadio can also connect to HF radios using audio and PTT ports. This will not give any virtual control head. At the moment we have no HF radios with virtual control heads.
Mimer SoftRadio connects to SIP phones and GSM-modems, and also to POTS phone connections. You can for example use this to connect to a sattelite phone using its POTS connection.
