Overview of Hodoyoshi Microsatellites for Remote Sensing and its future Prospect

There are various natural and man-made disasters and abnormal weather in the world. In order to monitor such disasters and weather, it is necessary to observe the earth frequently by using spaceborne, airborne and ground based observation equipments. Constellation of small satellites with optical sensor or radio sensor is very useful to conduct afore-mentioned observation. In 2014, more than 10 microsatellites for remote sensing with the same and different orbital altitudes will make constellation and these constellation will contribute to monitoring earth environment. This is the largest number of microsatellites launched in the same year in the history of microsatellites. In this paper, overview of Hodoyoshi microsatellites and future microsatellites using technology of system and components of Hodoyoshi technology is presented.
