摘要
卫星姿态变化时,静态红外地平仪的成像面与地平圆之间的夹角也会随着变化,因此会造成地平圆在地平仪成像面上成像的变化,进而导致地平仪大角度测量误差增大.为解决此问题,建立了随卫星姿态变化时地平圆在静态外红地平仪成像面上的成像模型,通过 STK仿真对该模型进行验证,并给出了一种基于该模型的地平仪测量误差校正的方法,为卫星姿态测量与控制提供补偿和精度保证.
Abstract
With the change of satellite attitude,the angle between the imaging plane of static-infrared earth sensor and horizon also changes.This will cause the image of horizon on the imaging plane is not a circle.So the measurement error occurs.To solve the problem,the horizon imaging model on the imaging plane of static-infrared earth sensor is built.The model is verified by STK simulation.At last,a way to correct the measuring error of static-infrared Earth Sensor is given based on this model.
