为统一描述编队飞行卫星中主从星的相对位置和姿态参数,利用对偶四元数,建立编队飞行卫星运动学模型,分析其物理意义,提出了基于对偶四元数的编队飞行卫星相对位姿描述的划船算法,并利用这一算法解算出相对位置和姿态参数,突破了传统方法中将卫星轨道和姿态分而治之的方式。仿真结果表明该算法科学合理,能够有效描述编队飞行卫星间的相对位置和姿态。
In order to unify the relative position and attitude parameters of the main and subordinate stars in formation flying satellites, the dual quaternion is used to establish the kinematics model of formation flying satellites, and its physical meaning is analyzed. The relative pose of the formation flying satellites based on dual quaternions is proposed Described the boating algorithm and use this algorithm to solve the relative position and attitude parameters, breaking the traditional method of satellite orbit and attitude divided and the way. Simulation results show that the algorithm is scientific and reasonable and can effectively describe the relative position and attitude of the formation flying satellites.
