Abstract: The position of a vehicle may be fixed by making range measurements to three known satellite and solving the resultant geometric problem. This paper argues that to answer the question "when there are random errors is the range measurements and in the satellites' positions, how accurate is this position fix?" It may be unncessary to solve the full geometric problem; it may suffice to solve rather a separate, simpler problem. It is shown that a single algebraic equation using a set of six scalar variables (three of which are random and three deterministic) completely determines the root-sum-squared error of the position fix. Graphs and ann example are provided for the application of the results.
