Abstract
Tianwen-1, the first mission of China’s planetary exploration program, accomplished its goals of orbiting, landing, and roving on the Mars. The entry, descent, and landing (EDL) phase directly determines the success of the entire mission, of which the guidance, navigation, and control (GNC) system is crucial. This paper outlines the Tianwen-1 EDL GNC system design by introducing the GNC requirements followed by presenting the GNC system architecture and algorithms to meet such requirements. The actual flight results for the whole EDL phase are also provided in this paper.
期刊介绍：
"China Space Science and Technology" is sponsored by the China Academy of Space Technology. It is an academic and technical journal that comprehensively and systematically reflects China's spacecraft engineering technology. The purpose of this journal is to "exchange scientific research results, explore cutting-edge technologies, activate academic research, promote talent growth, and serve the space industry", and strive to make "China Space Science and Technology" a first-class academic and technical journal in China.
This journal follows the principle of "let a hundred flowers bloom and a hundred schools of thought contend", promotes academic democracy, and actively carries out academic discussions, making this journal an important platform for Chinese space science and technology personnel to publish research results, conduct academic exchanges, and explore cutting-edge technologies; it has become an important window for promoting and displaying China's academic achievements in space technology.
