The Hughes vehicle location system (VLS), which locates and tracks one or more asynchronous aperiodic transmitters in either two or three dimensions, is described. It uses a dynamic receiver time-of-arrival (TOA) source selection, a direct hyperbolic position location solution, and an observation noise filter. For tracking a transmitter in two dimensions in an overdetermined system, hyperbolic geometric-dilution-of-precision (GDOP) is used to select an optimum subset of TOA triplets and to form a weighted position estimate. Particular emphasis is placed on the 2-D direct solution approach. The effect of observation noise on position estimation error in 2-D for an overdetermined system is demonstrated, and the derivation of the 2-D direct solution approach is presented.<>
