Abstract:

The random failure of the unmanned aerial vehicles (UAVs) in performing the task of remote sensing will result in the lack of timely response in the mission execution process, affecting the overall result of the mission or causing partial or complete failure of a mission. To address the failure issues, a redundant and fault-tolerant method for UAV remote sensing networking were proposed. With this method, the lead-follower drone group flight mode is used. Multiple networked drones can complete the designated flight tasks stably and reliably. The simulation result verifies the efficacy of the redundant fault-tolerant method, which can help solve the problem of missing data or task failure in the remote sensing of UAV.

Key words: unmanned aerial vehicle, remote sensing and telemetry networking, redundancy and fault tolerance, cybernetics
