摘要
提出了一种微型航天器间基于四元数的相对状态光学测量方法。首先介绍了测量系统结构,然后分析了利用四元数法解算航天器相对姿态的解算过程,最后通过仿真实验和实测试验验证了方法的正确性、实用性及可行性。该测量方法可直接用于航天器编队飞行及空间站交会对接过程、空间监视、目标拦截等应用领域中航天器间相对姿态测量。
A method of determining the relative states among spacecrafis based on quaternion is proposed. Firstly, the measurement system is introduced, and then the calculation of the relative spacecraft attitude is analyzed by using the quaternion, and finally the simulation results and experimental tests verify the correctness, practicality and feasibility of the method. The method can be widely used in the fields such as the formation flying of spacecrafts, the rendezvous docking with space station, the space surveillance and the target interception.
