Evaluation of system components for mobile navigation applications

A concept for the evaluation of navigation components with known system requirements and limitations makes use of modern structured analysis and design methods so that the requirements can be connected easily to efficient realizations. Design is divided into phases, each supported by and checked according to the previous phases or requirements. This method involves stepwise modeling of the application. The importance of each parameter is given by a normalized value selected by the designer. Components and subsystems to be used in navigation applications are modeled and evaluated. Results are shown as parameter weights. Selection of realization is done by comparing the evaluation matrices calculated for each choice. The evaluation of the total system estimates parameters such as accuracy, complexity, and cost. Some examples of applications are given including a delivery van, a wheel chair, and an automatically guided vehicle.<
