By measuring the time of arrival of the signal at the monitoring station, the distance of the signal source can be determined. The location of the signal can be determined by the distance from the signal source to each monitoring station. However, the absolute time is generally difficult to measure, and by comparing the time difference of the arrival of the signals at each monitoring station, a hyperbola with the monitoring station as the focus and the distance difference as the major axis can be formed, and the intersection point of the hyperbola is the position of the signals. AOA is a signal angle-of-arrival based positioning algorithm, which is typically a ranging based positioning algorithm, senses the direction of arrival of a transmitting node signal through some hardware device, calculates the relative bearing or angle between a receiving node and an anchor node, and then calculates the location of an unknown node by triangulation or other means.
