Wireless ground link-based aircraft data communication system with roaming feature

摘要

A system and method for providing a retrievable record of the flight performance of aircraft includes a ground data link unit that obtains flight performance data representative of aircraft flight performance during flight of the aircraft. A spread spectrum transceiver, such as a frequency hopping or direct sequence spread spectrum transceiver, is coupled to a data store. A transmitter is operative to download the flight performance data that has been accumulated and stored by the data store during flight over the spread spectrum communication signal. A ground based spread spectrum transceiver receives the spread spectrum communication signal from the aircraft and demodulates the signal to obtain the flight performance data.
