Research and Design of Azimuth-Only Passive Positioning System on a Circle

In order to reduce external interference, the electromagnetic wave signal should be reduced when UAV flying in formation, so the method of azimuth-only passive positioning is used to determine and adjust the position of UAV. This paper mainly studies the pure Angle passive positioning method on circular formation and quasi-circular formation. Due to its unique geometric characteristics, the positioning method and the quick and simple adjustment strategy in the face of slight deviation are studied and designed.
