Telecommunications Capabilities for the U.S. (United States) Defense Mapping Agency's Automated Notice to Mariners System

摘要

The Defense Mapping Agency (DMA) has developed capabilities to telecommunicate Automated Notice to Mariners to remote users including merchant ships at sea that have INMARSAT terminals. A Research and Development feasibility study of civilian and military telecommunications networks indicated that a large number of ANMS users are linked to the domestic telephone network, TWX, Telex, foreign telephone networks (CCITT modems), and AUTODIN I. DMA initiated a pilot program to link the ANMS Prime 400 computer to these networks enabling users with appropriate modems and terminals to receive ANMS by remote interactive query. The TWX, Telex, domestic, and foreign phone network interfaces have been implemented and tested. The AUTODIN I interface is under development and new capabilities such as computer to computer downline loading, transmission of graphics and ties to value-added networks are planned. (Author)
