摘要

2021年5月15日，“天文一号”任务将着陆器和朱荣探测器送到火星表面，这使中国成为第二个成功在火星上着陆并放置探测器的国家。天文一号任务的进入、下降和着陆(EDL)的制导、导航和控制(GNC)系统在保证成功着陆中起关键作用。本文介绍了天文一号EDL GNC系统的设计，包括GNC体系结构、方案和算法;此外，该系统还通过实验测试、数值模拟和遥测数据的实际飞行结果进行了验证。

Tianwen-1 Entry, Descent, and Landing Guidance, Navigation, and Control System Design and Validation

On 15 May 2021, the Tianwen-1 mission delivered a lander and the Zhurong rover to the Mars surface, which made China the second nation to successfully land and place a rover on that planet. The guidance, navigation, and control (GNC) system for the entry, descent, and landing (EDL) of the Tianwen-1 mission play keys role in guaranteeing a successful landing. In this paper, the Tianwen-1 EDL GNC system design is presented, including the GNC architecture, scheme, and algorithm; additionally, the system is validated through experimental tests, numerical simulations, and actual flight results from telemetry data.
