Aronson, E A

The mean and covariance of object location errors in time-of-arrival (TOA), time-difference-of-arrival (TDOA), and time-squared-difference (TSQD) systems are estimated in this report. These errors are due to errors in the assumed locations of the devices sensing the TOA data and in the measuarement of the TOA data itself. Also given is an analysis of the errors in these systems if the model vector is augmented with constraint-like equations. In the somewhat special case where system three-space geometry induces large location error covariances, an analysis is presented of the errors in an approximating two-space system.
