At present King Mongkut’s Institute of Technology Ladkrabang (KMITL), Chulalongkorn University, Chaingmai University, NICT as well as Kyoto University, Japan have cooperated to install a number of ionospheric monitoring equipment such as ionosondes, all-sky imager, magnetometer as well as GNSS receivers in various locations of Thailand such as Chiangmai, Chumphon, Bangkok and Phuket. Other GPS networks and ionosonde stations exist, whereby each network is owned and operated independently. For example, the Department of Land has 11 stations, the Royal Thai Navy owns three ionosonde stations, the Thai Meteorological Department houses 5-7 GPS receivers and the Aeronautical Radio of Thailand owns 3-4 GPS receivers. We aim to create the database of GPS data and ionospheric parameters in the Thailand location. The data-oriented activity at Thai Space Weather Information Center is hosted at KMITL at This activity presents the current status of GNSS and ionospheric monitoring networks and the efforts to create a GNSS and ionospheric database in Thailand. These data are important for the study of the ionosphere, Troposphere, GPS/GNSS technology, Geodesy and applications on the aeronautical navigation, satellite communication, earthquake study among others. In our plan, the data center with collaboration among various universities and agencies is being foreseen. At present, Thailand GNSS and Ionospheric Data Center is collecting the data from each GPS receiver as well as the ionosonde stations by using the script at each station to send the raw data through the internet.
