Title:
SUN SEARCH METHOD AND FOR THREE-AXIS STABILIZED SATELLITE, AND THREE-AXIS STABILIZED SATELLITE
Document Type and Number:
Japanese Patent JP3098419
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a sun sensor with a view field having a gap to be utilized only in the case where a measurement axis is oriented as desired relatively to the view field by generating a moment which is not parallel to the direction of the measurement axis by a flywheel device to be additively used.
SOLUTION: A control device is provided with a rotation speed gyro, and a rotation moment generating device which is not a flywheel device, and the rotation moment generating device is controlled based on a measurement signal of the rotation speed gyro. At this time, control τ=-kGGTω is used. Where, τis an inertia moment, k is a coefficient, G is a direction vector, and ω is a rotation vector of a satellite. Two reaction wheels RWX and RWZ of which rotation axes respectively coincide with X-axis and Y-axis, and two spin wheels FMW1, FMW2 of which rotation axes form the same angles θ to negative Y-axis with the opposite signs to each other, and which exist on the same plane with the axes are provided. A corresponding surface forms an angle ηto negative X-axis.
