为了解决单自由度太阳帆板在一般倾斜轨道中对日定向的局限性问题，一种常见的方法是让卫星提供辅助的姿态调整。对于对地观测的卫星，一般只要求卫星姿态保持能使有效载荷指向地面，即对卫星的俯仰角和滚转角有限制而对卫星的偏航角没有要求。因此可以调整卫星的偏航角来辅助太阳帆板对日定向。-In order to solve the single degree of freedom solar panels tilted orbits in the general limitations of the problem of orientation, a common approach is to provide support for satellite attitude adjustment. For earth observation satellites, satellite attitude generally only required to keep pointing to the ground to make the payload, ie the satellite pitch angle and roll angle is limited and yaw angle of the satellite is not required. Therefore, the satellite yaw angle can be adjusted to assist the solar panels of orientation.
