Abstract
A remote satellite which attitude are biased in long time operation,and constrainted by the general configuration,the double solarry array mounted slanted to the satellite body coordinate,meanwhile,in order to depress the influence to attitude stability,the solar array was drived toward Sun vector with the uniformly angular velocity.Aim to those feature,the method to calculate solar array panel incident angle is presentated in this paper.It has considered the attitude offset,yaw steering,J2 pertubation of earth and the effect of earth shadow,applying the transform of corordinate,the sun vector and the normal line of solar array are transformed in the same coordinate,calculated the orientation cosine number of value,accordingly,obtained the solar array sunlight incident angle.The four special point being selected,the calculate example is given,compare to the telemetry data obtained by coarse sun sensor on-orbital,the result indicate that they are well consistent.关键词
