Description

Technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method for cooperative and autonomous deployment of multiple unmanned aerial vehicle communication relay platforms. Background technique [0002] Line-of-Sight Communications (LoSC) has the characteristics of high information transmission rate and good confidentiality. Therefore, in many application backgrounds (for example, high-definition video live broadcast), it is necessary to maintain line-of-sight communication between execution units to achieve large Real-time transmission of capacity information. However, due to the occlusion of environmental obstacles and the limitation of communication distance, it is impossible to directly establish line-of-sight connectivity between different units. At this time, it is necessary to set the working environment and communication distance between the execution units as constraints. A series of relay nodes realize the estab...
