Abstract

The invention provides an all-day ball view field sun sensor and a determination method for a sun vector thereof.The sun sensor comprises a body structure, probes and a sun vector processor, wherein the body structure is in a rectangular pyramid shape and is provided with four side faces and a top face, the probes are arranged on the four side faces and the top face of the body structure and used for outputting current, and the sun vector processor is in communication connection with the probes and used for judging the number of the active probes and the quadrant where the projection of the sun vector in the XY plane and calculating the sun vector.According to the all-day ball view field sun sensor and the determination method for the sun vector thereof, on the condition that the requirement for the precision of the sun vector is met, the size can be decreased, the view field is increased, and coverage of an all-day 4 pi view field is achieved.

Description

technical field [0001] The invention relates to the field of determining the sun vector, in particular to a sun sensor with a full celestial field of view and a method for determining the sun vector. Background technique [0002] The sun sensor is used as the main attitude measurement instrument of the satellite control subsystem in the sun orientation mode and emergency mode at the initial stage of orbiting, and provides the satellite with the azimuth and elevation angle information of the sun light vector relative to the star coordinate system or the product coordinate system. The sun sensor takes the sun as the observation object, and its main technical indicators are the measurement field of view and measurement accuracy. The large measurement field of view is conducive to the rapid acquisition and orientation of the satellite to the sun, or the rapid realization of alignment to the sun in emergency mode. The high measurement accuracy means that the satellite has a high...
