Description: The problem of determining the location of a fixed point using range only data occurs in a variety of areas including military applications. An example is outlined and formed the incentive for the work herein. The application consisted of precisely locating hydrophones placed on a ship's null for the purpose of receiving acoustic signals to be used in calculating torpedo positions during a test. In this paper a method is developed which under the assumption of fixed system error input (in range data) produces the smallest possible error in locating the hydrophones. The goal is to determine the coordinates of a point in 3-dimensional space. For the purpose of simplicity this document first investigates the 2-dimensional version of this problem and then extends it to the 3-dimensional case.
