Research on position correction strategy for unmanned aerial vehicle formation based on pure azimuth passive positioning

In modern drone applications, precise positioning in formation flying is one of the primary issues that needs to be addressed. Among these, passive positioning technology is a commonly used and effective method for precise formation flying. However, most such methods require the transmission and reception of radio signals, which is inconvenient in scenarios requiring electromagnetic silence. This study proposes a drone formation positioning correction strategy based solely on azimuth passive positioning. This strategy, through geometric analysis and mathematical visualization techniques combined with polar coordinate positioning and a 0-1 planning model, corrects the positions of drones with deviations, optimizes flight efficiency, and enhances safety. Experimental results show that this method can effectively improve the positioning accuracy of drone formations under conditions of electromagnetic silence, demonstrating substantial practical value and prospects for wider application.
