Abstract
To facilitate GPS hardware selection and evaluate performance of vehicle integrated GPS hardware, including various types of GPS antennas and receivers, within different vehicle operating environments, embodiments of the invention are used to provide a simulator which does not require physical GPS hardware to simulate GPS system performance. Preferably, the simulator randomly generates one or more GPS system link budget variables, within predetermined performance bounds, in order to predict GPS system performance in a specific vehicle operating environment for a given antenna radiation pattern and/or GPS receiver. The simulator employs a Monte Carlo technique to evaluate the GPS system performance based on generated pools of link budget variables.
