| Abstract: | VHF data link plays a very important role in aviation communication today. At present, there are many kinds of aviation data link protocols,each of which has some advantages. In this paper, the protocol of VDL Mode 4 Data Link is first discussed. And then, the key technologies such as methods of network access,slot selection and channel management are explained.Finally,it is compared with other aviation data links and the advantages of VDL 4 Data Link are illustrated. This shows VDL4 can meet the FANS'' needs,and it is an aviation data link with rivalrousness. |
