The invention relates to a safe sun alignment method for configuring a single-wing sailboard satellite. The method comprises the following steps: judging an available state of a satellite actuator; setting a sun alignment axis according to the available state of the satellite actuator; if the on-satellite SADA and the reaction wheel in the X/Y axis direction are available, the SADA executes a zeroing action, the reaction wheel in the sun axis direction rotates to + 3000 Rpm, and the magnetic torquer executes a magnetic control sun alignment process; if only the reaction wheel in the X/Y axis direction is available on the satellite, the SADA keeps the original position, the available reaction wheel forming an acute angle with the normal line of the sailboard is rotated to 3000Rpm, the sun alignment axis is set to be in the direction of the available reaction wheel, and the magnetic torquer executes the magnetic control sun alignment process; if only the SADA is available on the satellite, the SADA executes a zeroing action, a sun alignment axis is set to be in the SADA zero position direction, and the magnetic torquer executes a magnetic control sun alignment process; if not, whether the included angle between the normal of the SADA sailboard and the main inertia axis is an acute angle or not is judged, if yes, the sun alignment axis is set to be in the SADA zero position direction, and the magnetic torquer executes the magnetic control sun alignment process; otherwise, entering an uncontrolled mode.
本发明涉及一种配置单翼帆板卫星安全对日方法,包括判断卫星执行器可用状态;根据所述卫星执行器可用状态,设置对日轴;若星上SADA及X/Y轴方向反作用轮可用,则SADA执行归零动作,对日轴方向反作用轮起旋至+3000Rpm,磁力矩器执行磁控对日流程;若星上只有X/Y轴方向反作用轮可用,则SADA保持原位置,将与帆板法线夹角成锐角的可用反作用轮起旋至3000Rpm,对日轴设置为该可用反作用轮方向,磁力矩器执行磁控对日流程;若星上只有SADA可用,则SADA执行归零动作,对日轴设置为SADA零位方向,磁力矩器执行磁控对日流程;若均不可用,判断SADA帆板法线与主惯量轴夹角是否为锐角,若为锐角,对日轴设置为SADA零位方向,磁力矩器执行磁控对日流程;否则进入无控模式。
