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 “Center of Excellence in GNSS and Space Weather (CEGS), King Mongkut’s Institute of Technology Ladkrabang, Thailand” and the sponsor of equipment (if any) such as SEALION Project, Kyoto University, etc.
Most of GNSS data and Ionosonde data that KMITL handles are through
- SouthEast Asian Low-latitude Ionospheric Network (SEALION) project
- Collaboration with ENRI (Japan) and AeroThai
- Chulalongkorn University, Kyoto University
