ABSTRACT:
A method of multilaterating the position of a target, including the steps of deploying a plurality of time synchronized receiving units in a network that allows the receiving units to communicate with a central processor; receiving a target signal from the target at each receiving unit; determining a time of arrival for the target signal at each receiving unit; determining position data for each receiving unit at the time when the target signal is received at each respective receiving unit; and using the time of arrival and position data for each receiving unit to determine the position of the target by multilateration. A system for carrying out the method is also disclosed.
