针对行星际微型航天器PROCYON(PRoximate Object Close flYby with Optical Navigation)的角动量控制问题,提出了一种太阳航行方法。该方法提出了一个简单,方便的实际应用控制在深空任务。所开发的方法的目的是防止角动量饱和,因为它控制的角动量的方向,通过使用太阳辐射压力(SRP)。航天器的SRP分布被建模为在浅太阳角下的平坦且光学均匀的板。该方法是通过只选择一个单一的惯性固定的姿态偏置动量状态。数值分析的结果表明,PROCYON的角动量被有效地控制在所需的方向上,使航天器能够在不通过反应控制系统进行动量减饱和操作的情况下生存至少一个月,并在燃料使用量非常有限(小于10克)的情况下生存两年。PROCYON的飞行数据还表明,PROCYON的SRP分布的建模误差在10− 9 Nm量级的小太阳角(< 10°)下足够小,并且能够保持目标周围的角动量方向。
This study proposes a solar sailing method for angular momentum control of the interplanetary micro-spacecraft PROCYON (PRoximate Object Close flYby with Optical Navigation). The method presents a simple and facile practical application of control during deep space missions. The developed method is designed to prevent angular momentum saturation in that it controls the direction of the angular momentum by using solar radiation pressure (SRP). The SRP distribution of the spacecraft is modeled as a flat and optically homogeneous plate at a shallow sun angle. The method is obtained by only selecting a single inertially fixed attitude with a bias-momentum state. The results of the numerical analysis indicate that PROCYON's angular momentum is effectively controlled in the desired directions, enabling the spacecraft to survive for at least one month without momentum-desaturation operations by the reaction control system and for two years with very limited fuel usage of less than 10 g. The flight data of PROCYON also indicate that the modeling error of PROCYON's SRP distribution is sufficiently small at a small sun angle (< 10°) of the order of 10− 9 Nm in terms of its standard deviation and enables the direction of the angular momentum around the target to be maintained.
