Northrop Grumman Corporation's Sperry Marine business unit today announced a partnership agreement with Thrane & Thrane AS under which Sperry Marine will market the Capsat Fleet 77 Broadband Satellite Communications System, designed to support the increasing demand for higher-speed data connections between ship and shore. Fleet 77 provides a constant two-way link to Inmarsat satellites, taking advantage of new-generation packet data switching technology enabling the ship's crew to integrate the vessel with onshore management systems via Internet-based systems from shipboard PC workstations, using standard software for e-mail and file transfer.
