Abstract

Relative navigation is crucial for spacecraft noncooperative rendezvous, and angles-only navigation using visible and infrared cameras provides a feasible solution. Herein, an angles-only navigation algorithm with multisensor data fusion is proposed to derive the relative motion states between two noncooperative spacecraft. First, the design model of the proposed algorithm is introduced, including the derivation of the state propagation and measurement equations. Subsequently, models for the sensor and actuator are introduced, and the effects of various factors on the sensors and actuators are considered. The square-root unscented Kalman filter is used to design the angles-only navigation filtering scheme. Additionally, the Clohessy—Wiltshire terminal guidance algorithm is introduced to obtain the theoretical relative motion trajectories during the rendezvous operations of two noncooperative spacecraft. Finally, the effectiveness of the proposed angles-only navigation algorithm is verified using a semi-physical simulation platform. The results prove that an optical navigation camera combined with average accelerometers and occasional orbital maneuvers is feasible for spacecraft noncooperative rendezvous using angles-only navigation.

航天器非合作交会多传感器数据融合纯角度导航算法的可行性分析

相对导航是航天器非合作交会的关键，而使用可见光和红外相机的纯角度导航提供了一种可行的解决方案。本文提出了一种多传感器数据融合的纯角度导航算法，用于推导两个非合作航天器之间的相对运动状态。首先，介绍了该算法的设计模型，包括状态传播方程和测量方程的推导。随后，介绍了传感器和执行机构的模型，并考虑了各种因素对传感器和执行器的影响。采用平方根无迹卡尔曼滤波器设计纯角度导航滤波方案。此外，引入了Clohessy-Wiltshire末端制导算法，获得了两个非合作航天器交会过程中的理论相对运动轨迹。最后，利用半物理仿真平台验证了所提出的纯角度导航算法的有效性。结果证明，光学导航相机与平均加速度计和偶尔的轨道机动相结合，对于仅使用角度导航的航天器非合作交会是可行的。
