摘要
为解决风云二号卫星连续区域观测时的精确姿态计算难题，提出了风云二号卫星红外云图的几何模型，并对得到的风云二号卫星姿态计算的关键参数进行了验证.在区域观测模式下，提出了几何距离约束进行模型的解算方法，得到了符合业务运行精度的结果.
Abstract
In order to obtain precise attitude calculation for FY-2 in regional observation, the model of FY-2 full disk infrared images is established. The key parameters for FY-2 attitude calculation resolved from the model is validated. In the regional observation, distance-based algorithm is presented, and the results meet the requirements of precision.
