HAII-ICGC :GNSS Project 2015/03/05

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 Objectives

Site selection Current +Plan Station in Thailand central part of Thailand 1.Located in central part of Thailand (flood area) 2.Baseline distance between station within km 3.Can be connected to current RTK networks (DPT&DOL) 6 stations

VRS system by Department of land (DOL) RTN system by Department of Public Works and Town & Country Planning (DPT) 6 Stations (on HAII-NIMT plan) 1 IGS-Station +5 Stations Reference Network in Thailand
