TanDEM-X任务是一项科学和商业地球观测任务，由两颗近距离飞行的卫星组成。机载自主系统可以有效地进行编队维护，减少操作工作量，在发生突发事件时提供更短的反应时间，并提高控制性能。TanDEM-X自主编队飞行（TAFF）系统就是为此目的而开发的，旨在取代常规作战期间的地面编队保持活动。TAFF于2010年10月首次启动调试，在此期间禁止自主使用推进器。随后，在2011年3月成功进行了闭环活动，证明了TAFF保持自主编队的能力。在对系统进行了简要的技术描述之后，本文介绍了在调试阶段和闭环运动中获得的关键结果。
Abstract The TanDEM-X mission is a scientific and commercial Earth observation mission comprising two satellites flying in close formation. The formation maintenance can be advantageously performed by an onboard autonomous system, which reduces the operational efforts, provides a shorter reaction time in case of contingencies and increases the control performance. The TanDEM-X Autonomous Formation Flying (TAFF) system has been developed for this purpose and is intended to replace the ground-based formation keeping activities during routine operations. TAFF has been activated for the first time in October 2010 for commissioning, during which the autonomous usage of thrusters was prohibited. Afterwards, a closed-loop campaign was successfully conducted in March 2011, demonstrating the capability of TAFF to maintain autonomously the formation. After a brief technical description of the system, the paper presents the key results gained during the commissioning phase and the closed-loop campaign.
