2
• To establish 1 IGS-nominated GNSS reference station with time control at NIMT with data center to synchronize data with IGS and the International Bureau of Weights and Measures (BIPM)
• To establish 5 GNSS reference stations in the flood risk area.
• To setup a data center at HAII to synchronize all existing and new GNSS reference stations in order to formulate national CORS network and provide services to support precise mapping applications
