Northrop Grumman Corporation's Sperry Marine business
unit announced that its Decca BridgeMaster E marine
radars have been type accepted by QinetiQ for display of Automatic Identification System
(AIS) data in accordance with the technical provisions of the International Maritime Organization Circular
"The BridgeMaster E is one of the first marine radars to be type accepted for display of AIS data," said John Robinson
, who heads Sperry Marine
's radar business group
"The ability to display AIS data on the radar screen significantly enhances situational awareness for the navigator by providing real-time information on target ships’ position movements and identity," said Robinson. "We have taken great care to ensure the AIS data is presented in such a way that it does not clutter the radar screen or overload the watch officer with too much data."
The BridgeMaster E radar processes data from the AIS and automatically displays the AIS targets, which are shown graphically within the radar circle in accordance with IMO-prescribed symbology. The navigator can view additional information about a selected AIS target in a separate target tote window. Any displayed AIS targets infringing the defined CPA/TCPA limits or entering a guard zone will raise an alarm to alert the watchkeeper.
The AIS function on the BridgeMaster E radar can be switched off at any time, reverting to the standard radar presentation. The AIS data will continue to be shown on the stand-alone AIS display.
A key feature of the BridgeMaster E radar is that it interfaces with the ship's AIS transponder via a simple IEC61162-2 serial cable link without the need for any additional pre-processor unit. The AIS interface can be supplied as a factory-fitted option or as a field upgrade kit for any BridgeMaster E series ATA or ARPA radar.
