未来大功率通信、广播卫星将采用大面积太阳翼,较强的太阳辐射压会引起轨道偏心率摄动量很大,影响东西向位置精度.本文着重讨论此种情况下的东西向位置保持修正策略;给出一种平经度漂移环方式;导出漂移环参数、最长修正周期及最小修正速度的计算公式并讨论了偏心率修正速度与修正周期的关系.比较了切向速度脉冲两脉冲控制方式及径向切向速度脉冲两脉冲控制方式所需的修正速度及允许的最长修正周期.
The future of high-power communications, broadcasting satellites will use a large area of the sun wing, a strong solar radiation pressure will cause the orbital eccentricity perturbation is large, affecting the east-west position accuracy.This article focuses on this case of the east-west position retention correction strategy ; A kind of longitude drift ring mode is given; the formula of the parameters of the drift ring, the longest correction cycle and the minimum correction speed are derived and the relationship between the correction rate and the eccentricity correction speed is discussed. And radial tangential speed pulse two pulse control mode required to amend the speed and allow the longest correction cycle.
