System design of LAPAN-CHIBA microsatellite

Development of compact and low power consumption synthetic aperture radar (SAR) by Center for Environmental Remote Sensing (CEReS), Chiba University make it feasible to bring such payload in microsatellites. Under collaboration with Center of Satellite Technology, Indonesian Institute of Aeronautics and Space (LAPAN), the concept LAPAN-CHIBA microsatellite is being developed. The mission of the satellite is for land cover mapping, disaster monitoring, Cryosphere monitoring, and oceanographic monitoring. In land cover mapping, the mission is to classify the forest and non-forest area, estimation of tree trunk height, and mangrove area monitoring. The system design of the microsatellite is presented in this paper. The resulted system design shows that the satellite could perform the mission while meeting the dimensional and weight requirement of most auxilary payload launches. The design also show that the satellite will have sufficient power to operate the payload during its pass in Indonesia and Japan area, and ocasionally on other areas on non-direct downlink mode.
