梯度使气流方向测量值向负梯度方向偏转。 圆柱探针和锥形多孔探针相比，气流方向测量误差对速度梯度更敏感，纵向梯度对俯仰角测量值的影响尤其大。
The velocity gradient, especially the perpendicular velocity gradient, leads the measuring error of flow angle with cylindrical probe to be larger than with conical multi-hole probe.
在对接面内与旁瓣转轴方向相垂直的方向上，重复定位误差对锁紧力位置误差最为敏感。
In the perpendicular direction to the rotation axis of the petal, the repeat position error is most sensitive to the position error of the locking force.
利用星敏感器测量所得的恒星星光方向信息，采用六状态变量推广卡尔曼滤波，得到卫星姿态误差和陀螺漂移误差信息并进行相应的修正。
Utilizing celestial observations from star trackers, a 6-state extended Kalman filter is adopted to correct the satellites attitude error as well as gyro bias error.
