Experiments of adaptive filters for kinemetic GPS positioning applied in road information updating in GIS
Zou Yi-jiang · Cehui kexue · 2003
The experiments for the road,information updating in the geographical information system by using GPS receiver mounted on a vehicle have been performed in Xian area of China. The navigation software accompanied with the GPS receiver, Sage filtering method and a new developed adaptively robust Kalman filtering method are employed and compared in the experiments. It is shown by experiments that the new adaptively robust filtering is not only simple in calculation but also robust in controlling the influences of the outliers of the GPS pseudoranges and kinematic state disturbing of the vehicle.
