麻省理工学院空间系统实验室正在开发SPHERES编队飞行测试平台，用于在二维实验室平台KC-135和国际空间站上运行。硬件由三颗直径23厘米、重3公斤的卫星或“球体”组成，它们可以控制它们的相对方向。每个球体由常规卫星的所有典型子系统组成。SPHERES的目的是为空军和NASA提供一个长期的、可扩展的、可扩展的试验平台，用于验证高风险的计量、控制和自主技术，这些技术是分布式卫星作为稀疏孔径任务（如TechSat 21、ST 3、TPF等）的一部分运行所需的。SPHERES利用了MODE系列动力学和控制实验室（STS-40、42、48、62、和平号），提供一个具有成本效益的实验室，利用空间的微重力条件与宇航员直接互动。本文将介绍SPHERES的目标、设计和硬件状况，以及使用测试平台进行验证的技术状况。
The MIT Space Systems Laboratory is developing the SPHERES formation flying testbed for operation on a 2-D laboratory platform, the KC-135, and the International Space Station. The hardware consists of three 23-centimeter diameter, three-kilogram satellites, or “spheres,” which can control their relative orientations. Each sphere consists of all the subsystems typical of a conventional satellite. The purpose of SPHERES is to provide the Air Force and NASA with a long term, replenishable, and upgradable testbed for validating high risk metrology, control, and autonomy technologies needed for operating distributed satellites as a part of sparse aperture missions such as TechSat21, ST3, TPF, etc. SPHERES draws upon the MODE family of dynamics and control laboratories (STS-40, 42, 48, 62, MIR) by providing a cost-effective laboratory with direct astronaut interaction which exploits the micro-gravity conditions of space. This paper will present the SPHERES objective, design, and hardware status as well as the status of the technologies to be validated using the testbed.
