Abstract : A method is derived for obtaining a weighted average of several redundant measurements of a common vector quantity so as to obtain the estimate of the vector with minimum error ''variance''. The method is general in the sense that the individual vector components may be made with unequal precision and with all possible correlations of error. Finally, the method is applied to a specific submarine-locating problem, where the submarine's position is to be estimated by use of hydrophones and a depth sensor. The results of dsing both weighted averages and simple averages are compared. (Author)
