This paper describes a methodology for accuracy evaluation of Global Positioning System (GPS) data, on the basis of a reference measurement system (RMS). The use of Global Navigation Satellite System (GNSS) for positioning in precise vehicle control needs previous evaluation and validation of the generated position information. The methodology, based on deviation analysis, is described using actual experimental data that allows a characterization of the quality of the positioning system through statistical distribution fittings, also validating the expected sensors responses. A system quality characterization method focused on accuracy is proposed, relating these findings with potential requirements for precise vehicle control systems. Actual results obtained by using the developed method of accuracy evaluation are shown.
