Research & Development
JAXA promotes three research and development programs and a fundamental research program that underpins them.
Unmanned Airplane for Radiation Monitoring System (UARMS)
Since June 2012, JAXA, in cooperation with the Japan Atomic Energy Agency (JAEA) , has been conducting research and development on a small Unmanned Aerial Radiation Monitoring System (UARMS).
JAXA's research focuses on:
- Unmanned aerial vehicle (UAV) system design including on-board system redundancy
- System safety technologies for small unmanned aircraft system (UAS) operations
- Automatic flight control technologies for more precise radiation monitoring
JAEA's research focuses on:
- Aerial radiation monitoring methodologies using UAS
- Light and small radiation detector system
The research is being conducted to be used for radiation-monitoring missions in the restricted area of Fukushima in the near future.
