| 摘 要： | 针对三轴稳定静止轨道气象卫星图像运动补偿技术,分析了轨道运动误差源对有效载荷成像仪成像光轴的影响.基于轨道确定数据,采用空间成像矢量修正方法,对轨道运动引起的光轴偏离进行补偿.根据高分辨率成像对光轴高指向精度的指标要求,研究了轨道确定误差和有效载荷伺服控制系统误差对图像配准精度的影响关系,并指出了进一步提高图像配准精度的措施.仿真结果表明了补偿方法的可行性.

| Abstract: | Aimed at the image motion compensation technology of three-axis stabilized geostationary meteorologic satellite,this paper analyzes the influence which the source error of orbit motion acts on the optical axis of the payload.Based on the orbit determination data,a vector correcting method of space imaging is presented for compensating the optical axis deviation caused by the orbit motion.The influence in connection with the orbit determination error and the payload control system error versus the image regi... |
