GPS/Galileo testbed using a high precision optical positioning system

Abstract

This paper presents a new approach for verifying and testing devices and algorithms that use position information determined by the Global Position System (GPS), a GPS testbed. A high precision tracking system is used measuring the position of an object and error terms and an offset are added in order to simulate its GPS position. The distribution of the position error of a common GPS receiver is analyzed in this paper and applied to a random number generator used for simulating the errors. Finally experiments with a real mobile robot are made to verify the presented system. © 2010 Springer-Verlag Berlin Heidelberg.
