Abstract The probability distribution of the location error based on range differences is presented first. After having the relationship between two common criteria for measuring location accuracy and the error covariance matrix, the optimal constellation is obtained for the case in which the radars are constrained in a sysmmetic area to locate a target in space by use of the minimum error ellipsoid criterion. Finally, some calculation results are given.
