The LEO Environments Observation Satellite【てんこう: Ten-Koh】
“Ten-Koh” is the satellite to observe LEO environments and the primary purpose is to provide valuable data for future development of satellites or operation.
Ten-Koh is GOSAT-2 and KhalifaSat piggy-pack satellite, and they will be launched together in the summer of 2018. GOSAT-2 is JAXA satellite to observe greenhouse gas, and KhalifaSat is a observation satellite for the government of Dubai. Ten-Koh will take the synchronous sub-recurrent orbit, which latitude is about 600km.
1．Purpose and Missions
Purpose① The observation of LEO environment and initial unveiling of the data
Recently, as the development of micro satellites by universities and other institutes has became active, breakdowns of them on LEO 2000km below have often occurred. It is said that most of these causes are cosmic radiation which have various energy level and come from the sun and so on.
To prevent these breakdowns, our Ten-Koh are going to measure various LEO environment parameters and unveil the data via internet initially.
Purpose② The measurement of degradation of advanced material on LEO
One of the purpose of Ten-Koh is to measure the degradation of advanced material which has potential to use in the future.
- Measurement of radiation, magnetic flux density and electron density on LEO for 6 month.
- Observation of degradation of advanced material for 6 month.
- Contribution to society or all over the world with telecommunication technology.
- Measurement of radiation, magnetic flux density and electron density on LEO for one year.
- Observation of degradation of advanced material for one year.
- Measurement of radiation, magnetic flux density and electron density on LEO for two years.
- Observation of degradation of advanced material for two years.
Ten-Koh shape is Quasi-spherical, which diameter is about 500mm and surrounded by solar cells. This satellite is constituted of structure, thermal control, attitude control, telecommunication, Bus power system and payload power system.
