In a TOA (Time of Arrival) system such as the GPS, a target location can be estimated from several range (distance) measurements between a target location and a reference point at known location. However, accuracy of estimated target location is very sensitive to target and reference points geometry. In this paper, we provide a measure of accurate estimated location of the target for a TOA system. This measure is the minimum singular value of an placement matrix that can be calculated from reference points and the nominal value of the target?fs location. We show that we could obtain good estimation when this value is large. |
