TDOA (Time Difference of Arrival)

Time Difference of Arrival (TDOA) is a method used to determine the location of a signal source, such as a cell phone or radio transmission. It works by measuring the time it takes for a signal to reach multiple receivers located at different positions. By comparing the arrival times at these receivers, the system can calculate the exact position of the source. This technique is commonly used in various applications, including GPS, mobile phone tracking, and locating emergency signals, as it allows for accurate positioning without requiring the signal source to send any location information.
