ASNARO（Advanced Satellite with New system ARchitecture for Observation）衛星のシステム概要

摘要

ASNARO satellite system outline and attitude control will be presented in this paper. ASNARO is a LEO satellite project for earth observation by optical sensor in sub-meter class. This satellite capture images which is less than 0.5 [m] GSD (Ground Sample Distance) by panchromatic band from 504 [km] high. This satellite is able to maneuver from nadir to +/-45 degree (Cross/Along Track), and has high agility of +/- 45 degree. This satellite observes the earth by four capturing modes, which are Snap Shot mode, Wide View mode, 3D mode and Strip Map mode. The limit of continuous taking pictures in wide view mode is analyzed in this paper.
