摘　　要：天问一号火星探测器成功实现了我国首次行星环绕探测,环绕器制导、导航与控制(GNC)系统负责行星际飞行和环绕飞行全过程的姿态与轨道控制、帆板和天线的指向控制等,确保探测器被火星捕获(MOI)进入环绕轨道,并保障器地通信链路、器间通信链路和器上能源安全。本文介绍了天问一号火星环绕器GNC系统的飞行阶段、系统设计、技术特点,以及关键阶段的设计和在轨飞行结果。The Tianwen-1 Mars probe has successfully realized the first planetary orbiting exploration in China.The guidance,navigation,and control(GNC)system of an orbiter is responsible for the attitude and orbit control,the pointing control of solar wings and antenna,etc.during the whole process of interplanetary flight and orbiting flight so as to ensure the communication between the orbiter and the Earth,the communication between the orbiter and the rover,the power supply,and that the probe can be captured by the Mars and thus enter the orbiting orbit.In this paper,the flight phase,system design,method features,and key phase design of the GNC system of Tianwen-1 Mars orbiter are described,along with the flight results.
