Wireless, frequency-agile spread spectrum ground link-based aircraft data communication system

摘要: A flight information communication system has a plurality of RF direct sequence spread spectrum ground data links that link respective aircraft-resident subsystems, in each which copy its performance is stored, with airport-located subsystems. The subsystems are coupled by way paths, such as land line telephone links, to remote operations control center. At the center, downlinked from plural aircraft parked at different airports analyzed. In addition, center may be employed uploading in-flight files, audio, video and navigation files aircraft.
