Azimuth Only Passive Positioning Adjustment of Unmanned Aerial Vehicles

Objective: This article starts from the actual environment, passive localization based on pure azimuth, introduces theoretical tools such as geometric calculation, and constructs a unmanned aerial vehicle positioning system on a circular formation.The positioning error is under and through the traversal method, it is determined that the unmanned aerial vehicle positioning system requires at least 4 positioning unmanned aerial vehicles under unknown numbering. Regarding the queue adjustment problem of drones, the relative position of the drone is obtained based on the positioning system, and then a vector is applied for adjustment. The adjustment is terminated by checking whether the Euclidean distance between the actual position and the expected position of the drone is less than the threshold. After testing, the model can adjust the queue error to within 7 rounds. In addition, to address issues such as collinearity and electromagnetic signal interference, the adoption of a reconfigurable positioning system has increased the accuracy and effectiveness of the drone positioning system. Through experiments, the model can accurately locate and adjust drones, and has little dependence on the geometric shape of drone formations, making it universal.
