Keywords:Space weather, High energy particle observation, Geostationary satellite

High energy particles, such as galactic cosmic rays, solar energetic protons, and radiation belt particles, that are hazard to spacecraft operation and radiation exposure of astronauts and aircrews. The necessity of operational space weather monitoring in space is increasingly high with the expansion of space utilization, including social infrastructure, such as navigation, communication, and broadcasting. To mitigate these risks from space environment hazard, the space weather forecast service group of the National Institute of Information and Communications Technology (NICT) started to develop CHARMS (Charging and radiation monitors for space weather) which considered to be installed onboard follow-on Japanese geostationary meteorological satellite. CHARMS will be responsible for operational space-based in-situ observation in geostationary orbit over Japan after launch scheduled in 2028. Current status of CHARMS instruments development is introduced in our presentation.
