Apparatus sharing situational awareness information of data link based on airborne data relay

摘要

The present invention relates to a status recognition information-sharing apparatus of an over-the-air repeater-based data link, which uses frequency mirroring and comprises a status recognition information-sharing node for sharing the status recognition information in an over-the-air repeater-based data link, wherein the method of operating the node enables assignment of slots and sharing of the status recognition information according to various attributes of a plurality of status recognition information-sharing nodes existing in the over-the-air repeater-based data link, and usability of a frame to be transmitted or received between nodes can be increased. In addition, because each status recognition information-sharing node directly assigns resources and performs information transmission without approval of a coordinator node, a load on the coordinator node can be reduced, and platforms having various attributes can efficiently share status recognition information.
