This paper presents a synthesizable low power VHDL model of a three-dimensional hyperbolic positioning system algorithm. The algorithm derives the equations needed to obtain an exact solution for the three dimensional location of a mobile given the locations of four fixed stations (like a GPS satellite or a base station in a cell) and the signal time of arrival (TOA) from the mobile to each station. The VHDL model of the algorithm was implemented and tested using the IEEE numeric_std package. The model can be easily synthesized for hardware implementation.
