| Abstract: |
| Supporting the four-dimensional(4D) trajectory based operation is one of the main trends in the development of civil aviation transportation technology in the future.The 4D trajectory based operation puts forward new requirements for the datalink application,datalink protocol stack and datalink transmission technology.On the basis of studying the foreign new technology of 4D trajectory based operation,the new characteristics of datalink applications such as Controller Pilot Data Link Communications(CPDLC) application and Automatic Dependent Surveillance Contract(ADS-C) application which support the 4D trajectory based operation are analyzed.And the working principle of Aeronautical Telecommunication Network/Internet Protocol Suite(ATN/IPS) protocol stack which supports the 4D trajectory based operation in the future is introduced.The characteristics of candidate communication links which support the 4D trajectory based operation such as broadband satellite communication and L-band Digital Aeronautical Communication System(LDACS) are also analyzed. |
