Abstract

To help future mobile agents plan their movement in harsh environments,a predictive model has been designed to determine what areas would be favorablefor Global Navigation Satellite System (GNSS) positioning. The model is able topredict the number of viable satellites for a GNSS receiver, based on a 3D pointcloud map and a satellite constellation. Both occlusion and absorption effects ofthe environment are considered. A rugged mobile platform was designed to collectdata in order to generate the point cloud maps. It was deployed during the Canadianwinter known for large amounts of snow and extremely low temperatures. The testenvironments include a highly dense boreal forest and a university campus compris-ing high buildings. The experiment results indicate that the model performs well inboth structured and unstructured environments.
