MOS-1航空機検証実験の成果について

抄録

Marine Observation Satellite-1 (MOS-1) will be launched by a N-II launch vehicle from Tanegashima Space Center, NASDA in the January-February period of 1987. Main mission objectives of MOS-1 are to observe ocean, land and atmosphere using three radiometers (MESSR, VTIR, MSR) covering visible, nearinfrared, thermal infrared and microwave wavelength region, and to establish fundamental technologies of earth observation satellite total system.
In order to accomplish these objectives, NASDA is developing MOS-1 space segment and ground segment and planned MOS-1 Verification Program (MVP) to evaluate the total MOS-1 system by using MOS-1 data obtained after launch of MOS-1. In order to develop MOS-1 data distortion correction method and earth observation system evaluation method and to prepare for the MVP, NASDA conducted airborne observation experiments using three radiometers mounted on an aircraft turbo-prop type "Merlin IV A' equivalent to MOS-1 MESSR, VTIR and MSR in cooperation with cooperative agencies from November, 1984 through September, 1985. NASDA obtained airborne MESSR, VTIR, MSR data and aerial photograph data in winter and summer during 11 days over several test sites in Kanto of Honsyu and in Hokkaido. Cooperative agencies obtained ground/sea truth data.
By using airborne data and ground/sea truth data, distortion correction algorithms and observation system evaluation algorithms have been developed. These algorithms have been installed in MOS-1 data processing facility. Based upon the airborne observation experiments, Japanese first satellite verification program MVP will be performed with domestic and foreign investigators. MVP will be continued during mission life of MOS-1. MOS-1 data will be sold to general users, while MOS-1 data are free of charge when these data will be used for the MVP.
