Abstract

This paper presents a system design approach for vehicle positioning systems. Global Navigation Satellite Systems (GNSS) and inertial sensors are major positioning measurements used in this approach. A number of phases are designed in this approach including: system architecture design using an estimator, GNSS error modelling, estimator low level design, simulation and experiment design, frequency domain simulation, time domain experiment, sensor selection and deployment decision making. This approach enables to model GNSS errors from end user's view point, and choose low cost inertial sensors to meet positioning system requirements using a new sensor selection criterion.
