Public trust. Wuhan, 27 Feb (Ma Furong Wu) On the 27th, the "Qixing-1" micro-nano satellite of Wuhan University was launched by the Long March-8 Yao-2 carrier rocket and entered the scheduled orbit. According to the feedback from the satellite launch site, the satellite successfully entered the scheduled orbit, and 14: 08+0 1 received the satellite monitoring and control signal. The satellite works normally, and will provide experimental and teaching data for personnel training in the field of aerospace information in the later stage.
"Micro-nano satellite" refers to a satellite with small volume and weight. "Morningstar-1" is the first programmable micro-nano satellite in China, which has visible hyperspectral and luminous multispectral modes. The whole satellite weighs about 19kg. It is equipped with a visible light camera and an infrared camera. It can obtain hyperspectral, luminous and infrared remote sensing images, and is typically used in water environment monitoring, regional forest coverage observation, urban planning and regional economic development trend analysis.

Guang Jin, a professor at the School of Remote Sensing Information Engineering of Wuhan University, said that the development of "Qixing-1" started from 2065438+September 2009. In order to cultivate compound talents in the field of remote sensing, the project decided to let students play a leading role from the beginning of research and development. After independent application and selection, more than 50 undergraduate and graduate students have participated in * * * for more than two years.
"Students' enthusiasm for participation is very high, and they have provided many' golden ideas'". Guang Jin said that in the past, the images obtained by satellites were black and white. When developing "Qixing-1", some students put forward the idea of color image, and the team tackled the problem all the way, and finally realized the color collection of luminous remote sensing images.
Bathen Chow, a third-year graduate student majoring in photogrammetry and remote sensing in Wuhan University, participated in the integration and testing of Venus-1 sensor. "The biggest feeling is to exercise your practical ability." He admits that satellite development involves many fields of knowledge such as optics, circuits and computers. Everyone consulted the information, consulted the tutor, and saw that the theory had become a real thing, which made them feel a sense of accomplishment and pride.

"I never thought I could participate in building satellites when I was a student." Ke Shiyun, a graduate student of Wuhan University, participated in the construction of the ground processing system of Venus-1. This experience also strengthened her determination to engage in the aerospace industry. Today, she is still involved in the development of the "Luojia III" satellite of Wuhan University.
According to reports, "Venus 1" is the first satellite in the Venus constellation plan, which consists of several remote sensing satellites. After the operation of Venus-1, the remote sensing satellite ground station of Wuhan University in Jiangxia will be responsible for ground measurement and control and data reception, and become a "space laboratory" for teachers and students of Wuhan University, which is convenient for teachers and students to carry out autonomous measurement and control and on-orbit experiments and master related technologies and applications of remote sensing satellites.
