This paper presents an on-board, centralized autonomous navigation algorithm able to reconstruct the trajectories of a fleet of CubeSats relative to an asteroid binary system. The algorithm is executed on-board the main spacecraft, which takes relative measurements using a narrow optical camera and an additional relative measurement, being inter satellite ranging in this paper. The image processing algorithm detects and tracks the CubeSats, deriving line-of-sight measurements. A non-linear estimation filter is employed to reconstruct the trajectory. The algorithm is tested using high-fidelity trajectory simulator and synthetic images generation routines.

Didymos系统周围多个立方体的集中自主相对导航

本文提出了一种机载，集中式自主导航算法，该算法能够重构相对于小行星二元系统的CubeSats舰队的轨迹。该算法在主要航天器上执行，该航天器使用窄光学相机进行相对测量，并进行额外的相对测量，本文将其作为卫星间测距。图像处理算法检测并跟踪CubeSat，从而得出视线测量值。使用非线性估计滤波器来重构轨迹。使用高保真轨迹模拟器和合成图像生成例程对算法进行了测试。
