lateration
Lateration is a technique used in various fields, including geolocation, seismology, and wireless communication, to determine the position of an object or event. The term "lateration" is derived from the Latin word "latere," meaning "to lie." It refers to the process of measuring the time difference of arrival (TDOA) or the time of flight (TOF) of signals from multiple reference points to a target. By analyzing these measurements, the distance between the target and each reference point can be calculated. Using geometric principles, such as triangulation or multilateration, the position of the target can be estimated.
In geolocation, lateration is commonly used in Global Navigation Satellite Systems (GNSS) like GPS, where the
The accuracy of lateration depends on various factors, including the precision of the time measurements, the
