The Canadian Coast Guard has placed orders for 141 Saab TransponderTech marine DGPS receivers in a move to upgrade shipboard navigation systems throughout the fleet. The new Saab DGPS antennas and sensors will replace the stand-alone DGPS receivers currently installed on the vessels. They will be integrated with the existing Saab R4 Automatic Information Systems (AIS) installations, providing a seamless DGPS/AIS solution sharing a common user interface and display. The DGPS systems will be fitted on Canadian Coast Guard icebreakers, buoy tenders, fisheries patrol vessels and search-and-rescue cutters during 2006. The products are being supplied by Austin Navigation, a Saab authorized dealer in Canada.
