CTOC Introduction

Relying on The Chinese Society of Theoretical and Applied Mechanics, the China Trajectory Optimization Competition was started in 2009.
The first edition was initiated and organized by Tsinghua University. After that, the champion team of the competition was responsible for organizing the next competition. This organizing mechanism ensures the long-term sustainable development of the competition in a scientific and fair environment.

The Chinese Society of Theoretical and Applied Mechanics

The Chinese Society of Theoretical and Applied Mechanics was established in February 1957 under the joint initiative and organization of famous mechanics such as Xuesen Qian, Weichang Qian, yonghuai Guo and Peiyuan Zhou.

The Chinese Society of Theoretical and Applied Mechanics is a legally registered and non-profit academic social group voluntarily formed by technical researchers in the mechanics of the country. It is an important social force in the development of Chinese mechanics science and technology, and is a component of the China Association for Science and Technology. It is established to unite and organize mechanics researchers across the country to carry out international and domestic academic exchanges, promote non-governmental scientific and technological cooperation and exchanges,and establish mechanics journals to promote the development and prosperity of mechanics.

Harbin Institute of Technology

Harbin Institute of Technology (HIT) was established in 1920 in Harbin, Heilongjiang, China. In 1954, HIT became one of China's first six leading universities. Presently HIT is a member of China's top nine University Union (C9). It is a National Key University with science and engineering as its core and has developed with management, liberal arts, economy, law and other disciplines.

HIT is a university characterized by aerospace. HIT has successfully launched 20 microsatellites, including the "longjiang-2" satellite, which has independently completed Earth-Moon transfer, near moon braking and circumlunar flight for the first time by microsatellites in the world.

June 7, 2020 is the 100th anniversary of Harbin Institute of Technology. In the special issue published by Nature, Zhou Yu, Academician of Chinese Academy of Engineering and President of HIT, published an article called Piloting Science and Engineering Through Innovation. In this article, President Zhou Yu introduced the history, advantages and characteristics of HIT to the global scientific and technological talents, as well as the marvelous achievements of hit in scientific research. In addition, the article also introduced the basic situation of international exchange and cooperation, the pattern of “one university three campuses”, and looked forward to the development prospect of the school in the new century.

Introduction of CTOC11 logo

The CTOC11 logo is composed of three elements: elliptical
orbits, earth, and Dongfanghong-1 satellite. Two elliptical
orbits fit the theme of the trajectory optimization
competition. The dark and white eccentric circle represents
the earth with twilight lines. Dongfanghong-1 is China's
first man-made satellite and a symbol of China's exploration
of the universe.
