Welcome to the Thai GNSS and Space Weather Information Data Center hosted at King Mongkut’s Institue of Technology Ladkrabang (KMITL).  In the future, we hope to cover the forecasting service as well.

The Data Center serves the following purposes:

  1.  Maintain the GNSS, ionospheric and sensor database from the stations which we operate and maintain, data servers and backup. 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.
  2.  Provide the observation of the followings:
    • Solar parameters
    • Space Environment parameters
    • GNSS and Ionosphere
      • Quick-look ionogram, analyzed parameters such as foF2, h’F, M3000(F2) and Spread F  statistics, etc.
      • Slant TEC, vertical TEC
      • Scintillation (S4 index)
  3.  Provide data downloading service for research.
  4.  Develop data products from these observations and support research operations at our Laboratory.
  5.  Provide NTRIP service from several GNSS stations.
  6.  Disseminate the knowledge and awareness of GNSS, Ionosphere and Space Weather Effects in our daily life such as
    • HF and satellite Communication outage (maritime, aviation, disaster)
    • Aeronautical navigation (Aviation),  Radiation dose to aircrafts
    • Power Plant disruption
    • Ionosphere study, Tropospheric study (water vapor),
    • GNSS Accuracy (Precisioned agriculture, UAV, Autonomous cars, Smart City),
    • Earthquake and disaster
    • Accumulated charging on satellites and others
