The position of a Wireless Transceiver (WT) is estimated using the Time Of Arrival (TOA) at several Monitoring Sites (MS) of the signal transmitted by the WT. Several sites are used to solve for the coordinates of the WT using hyperbolic trilateration. A time reference is used to synchronize the Mon ...

A wireless location system uses a statistical approach, in which a probability distribution is trained that relates reliable observations of a signal parameter to a known measure of location. The probability distribution is then used to locate a mobile transmitter when addition observations are avai ...
