Saab and Trimble to Integrate Solutions for DGPS Transmissions

September 16, 2008

Trimble and Saab TransponderTech AB are cooperating to integrate their differential GPS (DGPS) solutions for enhanced marine navigation.

Saab and Trimble will integrate their marine navigation solutions to deliver DGPS error correction messages to ships at sea through automatic identification system (AIS) coast stations and networks. The DGPS messages transmitted on AIS frequencies will augment the existing marine DGPS broadcasts from coastal beacon stations.

The two companies are collaborating to develop interfaces connecting Saab's AIS and Vessel Tracking Management & Information System (VTMIS) with Trimble DGPS reference station and integrity monitoring software. The integrated solution will utilize Trimble's Charisma and software for advanced integrity monitoring of the DGPS data prior to transmission through both the beacon transmitters and AIS stations. The integration will also permit the Saab AIS/VTMIS operator to monitor the performance of both DGPS services.
