隼鸟2号是日本从近地小行星龙谷进行的样本返回使命。隼鸟2号宇宙飞船于2014年12月3日发射，并于2018年6月27日抵达龙宫。它在那里停留到2019年11月13日，进行原位观测和土壤样本采集，并将于2020年11月或12月返回地球。在小行星停留期间，飞船于2019年2月首次成功进行了着陆操作。由于龙宫的地表崎岖不平，到处都是巨石，所以最终找到的目标区域只有3米的半径。有几个技术挑战需要克服，包括苛刻的制导，导航和控制精度，以实现着陆操作。本文介绍了制导、导航和控制系统的策略和技术细节。飞行结果证明，这些系统的性能令人满意，在很大程度上促进了行动的成功。
Hayabusa2 is a Japanese sample return mission from the near-Earth asteroid Ryugu. The Hayabusa2 spacecraft was launched on December 3, 2014, and arrived at Ryugu on June 27, 2018. It stayed there until November 13, 2019 for in situ observation and soil sample collection, and will return to the Earth in November or December 2020. During the stay at the asteroid, the spacecraft performed a touchdown operation successfully for the first time in February 2019. Since the surface of Ryugu was rough and full of boulders, a targeted area finally found had a radius of only 3 m. There were several technical challenges to overcome including demanding guidance, navigation and control accuracy to realise the touchdown operation. In this paper, strategies and technical details of the guidance, navigation and control systems are presented. The flight results prove that the performance of the systems was satisfactory and largely contributed to the success of the operation.
