Accuracy Estimation of a Low-Cost GPS Receiver Using Landmarks On Aerial Images

Abstract

The number of applications that use low-cost global positioning system (GPS) receivers have dramatically increased over the years in the scientific, military and civil fields. The accuracy in the position estimation of these low-cost GPS receivers is crucial for a successful operation. This research focuses on the accuracy estimation of a low-cost GPS receiver based only on position measurements, and landmarks in aerial images. In addition, a comparison with respect to a commercial receiver and coordinates obtained using differential GPS (DGPS) is performed. The accuracy estimation procedure shows a meter level accuracy for pedestrian outdoors applications for a low-cost u-blox NEO-6M GPS receiver.
