In this final thesis we will develop an additional feature for the IDOCAS system. The goal is to develop an Airport-Server with its own protocol-stack. This stack includes a protocol for the communication and for the application procedure for IDCOAS-Clients at the Aiport-Server. The communication happens between server and client exclusive over radio. The hardware which we used was already developed by the ZHW.

This protocol-stack should be used for the synchronisation of the obstacle database of the IDOCAS-Client. It should be possible to update the database over radio and the own protocol stack. This task will happen if the client has landed.
