\n\t\tResearch awarded \u201cbest paper award\u201d at Homeland Security conference<\/p>\n


\n\tKINGSTON, R.I. \u2013 December 16, 2010 \u2013 Commercial global positioning systems (GPS) like those dispensing driving directions in cars can provide reliable location information to within 20 feet, while an augmented system used primarily by the Coast Guard for navigation is even more accurate. <\/p>\n


\nNow a 溏心vlog免费B站 engineering researcher says that the augmented system, called Differential GPS or DGPS, can also be used to concurrently transmit emergency messages or other relevant data for use by Homeland Security or other government agencies.<\/p>\n


\n\u201cThe DGPS system has significant capability for use beyond that of its current mandate,\u201d said Peter Swaszek, 溏心vlog免费B站 professor of electrical engineering, whose paper co-authored with Coast Guard researchers Richard Hartnett and Keith Gross won the top award at a Homeland Security conference in November sponsored by the Institute of Electrical and Electronics Engineers. \u201cWe believe that simultaneous transmission of the current navigation correction information and additional messaging could be accomplished at very minimal cost and with minimal impact on current users.\u201d<\/p>\n


\nThere are 88 DGPS towers located around the continental United States that improve the accuracy and integrity of the satellite-based GPS system. Swaszek said that the Coast Guard has been using and testing the augmented system since the 1980s because the accuracy of the commercial system isn\u2019t precise enough for landing aircraft, docking large ships and other navigation needs. The 溏心vlog免费B站 researcher said that the DGPS towers are robust in the face of challenging weather conditions and could be used to send emergency messages if, for example, a hurricane knocks out television or radio signals.<\/p>\n


\n\u201cThis could be a great tool for the Department of Homeland Security because it uses existing infrastructure and fills a need within the emergency communication system,\u201d Swaszek said. \u201cAnd you can transmit a maximal amount of information across this link.\u201d<\/p>\n


\nThe DGPS system is not a two-way communication channel, so it could only be used to broadcast information to users, and it cannot transmit a voice signal, only text and other low data-rate applications. But Swaszek envisions a wide variety of uses. He said that anyone with the proper equipment \u2013 a baseball-sized antenna \u2013 could receive the information.<\/p>\n


\nSwaszek said that his proposed expansion of the DGPS system still needs additional testing, and he is meeting with potential users to seek interest and funding for further tests, including the New York Port Authority and the Mitre Corp. He believes the system could be operational within three years.<\/p>\n


\n\u201cI am incredibly pleased that this research got recognized at the IEEE conference,\u201d Swaszek said, \u201cI hope that those in government will see it as a useful tool and they can give it a push to get it implemented.\u201d<\/div>\n","protected":false},"excerpt":{"rendered":"
