Data Policy
In general, researchers who are interested in GNSS data and Ionosonde data which are handled by KMITL can make a request by filling out the form below. If there is no objection from our partners, we will then send you the downloadable links. When publishing research works from downloaded data, you will need to acknowledge “Thai GNSS and Space Weather Information Center, King Mongkut’s Institute of Technology Ladkrabang, Thailand” and the sponsor of equipment (if any) such as SEALION Project, Kyoto University, etc.
To request the GNSS or Ionosonde data (Ionograms), please click here to download the Data Request Form.
This file requests researcher(s) or student advisor(s) to fill in the information and send it back to e-mail:
- pornchai.su@kmitl.ac.th or
- jirapoom.bu@kmitl.ac.th
Note: more information will be provided during the Data request process.
Most of GNSS data and Ionosonde data that KMITL handles are through
- SouthEast Asian Low-latitude Ionospheric Network (SEALION) project
- Coolobaration with ENRI (Japan) and AeroThai
- Chulalongkorn University, Kyoto University
