The Navigation Laboratory has equipped with modern positioning equipment, such as GNSS receivers, INS, optical motion tracking system, and indoor positioning facilities. It has a platform for GNSS RTK service and generates real-time GNSS related products, i.e. water vapor content and ionosphere TEC distribution. The main research directions include GNSS theory and applications in positioning and environment monitoring, technologies for establishing urban positioning infrastructure, integrated navigation systems, Intelligent Transportation Systems (ITS) and Location Based services (LBS).
