一种卫星动量轮控制下的变轨间隔确定方法
摘要：
本发明公开了一种卫星动量轮控制下的变轨间隔确定方法，包括以下步骤：（1）计算动量轮能够承受的最大角动量变化；（2）获取轨控推力器带来的干扰力矩；（3）计算干扰角动量的幅值；（4）计算动量轮控制下的变轨时间间隔；（5）地面注入本次变轨序列的变轨数据块；（6）执行变轨。本发明方法在动量轮控制下进行，一方面不至于动量轮饱和，另一方面，本发明设计的变轨方式不需要姿控发动机喷气，仅仅需要轨控发动机喷气即可实现变轨，节省燃料。
摘要（英）：

The invention discloses a method for determining orbital transfer interval under control of a satellite momentum wheel. The method includes the steps of firstly, calculating maximum angular momentum variation which can be borne by the momentum wheel; secondly, acquiring disturbance torque brought by a orbital control thruster; thirdly, calculating amplitude interfering angular momentum; fourthly, calculating orbital transfer time interval under control of the momentum wheel; fifthly, loading orbital data blocks of a orbital transfer sequence on the ground; and sixthly, performing orbital transfer. The method is performed under control of the momentum wheel, so that saturation of the momentum wheel is avoided. Jetting of a posture-control engine is unnecessary, orbital transfer can be achieved by jetting of an orbital control engine, and fuel is saved.
