Abstract: This invention is related to automatic monitoring and collaboration among aircrafts. Specifically, an aircraft receives the current and future state of adjacent aircrafts by broadcast, then analyzes the start time of collaborative tasks. Base on the start time and prior knowledge, it adjusts automatically the prediction accuracy requirements of its future states, the check interval of predicted state errors and the minimum check interval. And it makes a new prediction and broadcasts new future states based on the check results of prediction errors. In the invention, an aircraft does not periodically broadcast its states, but broadcasts irregularly its future states according to its current tasks, its states and surrounding environment. The invention guarantees that collaborative tasks can be can be correctly carried out among aircrafts while it reduces the bandwidth requirement of wireless communication. It provides guarantee of high density flight and collaboration among many aircrafts.

Abstract: Methods and systems of active discovery and collaborative collision avoidance are described for aircrafts. Specifically, an aircraft predicts firstly the four-dimensional information of its short future flight path based on existing information, then shares the information actively among its adjacent aircrafts, realizes finally collaborative collision avoidance based on the future flight paths of adjacent aircrafts. The described methods contain the following steps: prediction and broadcast of short future flight path, broadcast reception and analysis and collision avoidance, and resumption of planned path and state. According to the methods, a system is also described to implement the above method and it contains seven corresponding modules. Since sharing the future information rather than the past information among aircrafts, the advantage of this intervention is strong real-time, low computation complexity, low cost, and more aircrafts accommodated in the same space.
