Title:
INTEGRATED UNMANNED AND MANNED UAV NETWORK
Document Type and Number:
WIPO Patent Application WO/2024/054628
Kind Code:
A3
Abstract:
The operation of multiple unmanned vehicles (UAV) commanded and supported by a manned "Tender" air vehicle carrying a pilot and flight manager(s). The "Tender" is equipped to flexibly and economically monitor and manage multiple diverse UAVs over otherwise inaccessible terrain through wireless communication. The architecture enables operations and analysis enabled by means to detect, assess and accommodate change and hazards on the spot with effective human observation and coordination. Further, the optimal trajectories for UAVs to collect data from sensors in a predefined continues space. The system formulates the path-planning problem for a cooperative, and homogeneous swarm of UAVs tasked with optimizing multiple objectives simultaneously as its objectives are maximizing accumulated data within a given fly time and designed data clouding processing constraints as well as minimizing the probable imposed risk during UAVs mission. The risk assessment model determines risk indicators using an integrated SORA-BBN (the Specific Operation Risk Assessment - Bayesian Belief Network) approach while its resultant analysis is weighted through AHP ranking model. To this end, as the problem is formulated as a convex optimization model, therefore, the system has a low complexity Multi-objective reinforcement (MORL) algorithm with a provable performance guarantee to solve the problem efficiently. The MORL architecture is successfully trained and allow each UAV to map each observation of the network state to an action to make optimal movement decisions. This network architecture enables the UAVs balance multi objectives. Estimated MSE measures show that the introduced algorithm followed decreasing error in learning process with the increase in the epoch number.
