摘要

随着绕地球轨道运行的驻留空间物体(RSO)数量的增加,发生碰撞的风险也随之增加,要降低这种风险,就必须在任何给定时间内对视野内尽可能多的 RSO 进行探测、识别、定性和跟踪,这一研究领域被称为空间态势感知(SSA)。为了开发 RSO 检测和定性算法,需要包含 RSO 的星场图像。这些图像可以从传统上用于姿态确定的星体跟踪器中获得。尽管星体跟踪仪图像的分辨率较低,但仍有可能用于星地卫星导航。以这种双重用途的方式使用星轨跟踪器的好处是,可以充分利用已在轨道上的现有星轨跟踪器技术,无需向太空发射昂贵的新设备。2022 年 8 月,我们在一个平流层气球上发射了一个立方体卫星级有效载荷--驻留空间物体近空间天体测量研究(RSONAR)。该有效载荷的主要目的是展示一种两用星体跟踪器,用于从类似太空的环境中对驻留空间物体进行成像和分析,从而为空间安全保障领域提供帮助。在 2022 年活动的经验和教训的基础上,我们在 4U 启发的立方体卫星平台上开发了下一代两用相机,命名为 RSONAR II。该有效载荷于 2023 年 8 月成功发射。利用RSONAR II有效载荷,我们开发了一个实时、多用途成像系统,其中有两个成本不同的主相机,可以实时调整成像参数,以评估每种配置对RSO成像的有效性。我们还进行了星载 RSO 探测和姿态确定,以验证我们算法的性能。此外,我们还实现了下行链路功能,以验证有效载荷在飞行过程中的性能。为了增加测试算法的图像种类,我们在整个任务期间改变了其中一台相机的分辨率。在本文中,我们展示了用于未来 SSA 任务的两用星体跟踪器系统,并比较了用于 RSO 成像的两种不同传感器选项。

Technology Demonstration of Space Situational Awareness (SSA) Mission on Stratospheric Balloon Platform
As the number of resident space objects (RSOs) orbiting Earth increases, the risk of collision increases, and mitigating this risk requires the detection, identification, characterization, and tracking of as many RSOs as possible in view at any given time, an area of research referred to as Space Situational Awareness (SSA). In order to develop algorithms for RSO detection and characterization, starfield images containing RSOs are needed. Such images can be obtained from star trackers, which have traditionally been used for attitude determination. Despite their low resolution, star tracker images have the potential to be useful for SSA. Using star trackers in this dual-purpose manner offers the benefit of leveraging existing star tracker technology already in orbit, eliminating the need for new and costly equipment to be launched into space. In August 2022, we launched a CubeSat-class payload, Resident Space Object Near-space Astrometric Research (RSONAR), on a stratospheric balloon. The primary objective of the payload was to demonstrate a dual-purpose star tracker for imaging and analyzing RSOs from a space-like environment, aiding in the field of SSA. Building on the experience and lessons learned from the 2022 campaign, we developed a next-generation dual-purpose camera in a 4U-inspired CubeSat platform, named RSONAR II. This payload was successfully launched in August 2023. With the RSONAR II payload, we developed a real-time, multi-purpose imaging system with two main cameras of varying cost that can adjust imaging parameters in real-time to evaluate the effectiveness of each configuration for RSO imaging. We also performed onboard RSO detection and attitude determination to verify the performance of our algorithms. Additionally, we implemented a downlink capability to verify payload performance during flight. To add a wider variety of images for testing our algorithms, we altered the resolution of one of the cameras throughout the mission. In this paper, we demonstrate a dual-purpose star tracker system for future SSA missions and compare two different sensor options for RSO imaging.
