The design, integration and testing of the satellite are all done on the campus of Wuhan University.In order to cultivate interdisciplinary talents in the field of remote sensing, the project has decided to let students play the leading role since its launch in 2019, with more than 50 students, ranging from undergraduates to postdocs, participating.The qiming research and development team has overcome difficulties in integrated satellite design, payload development and attitude control. The final research and development cost is only about 5 million yuan, which maximizes benefits, Jin said.In the future, Wuhan University also plans to launch satellites such as Luojia NO. 2 01, Luojia No. 3 01, and Luojia No. 3 02.Disclaimer: The copyright of this article belongs to the original author, if there is a source error or infringement of your legitimate rights and interests, you can contact us through email or wechat, we will deal with it in time.Email address: jpbl@jp.jiupainews.com;Wechat id: Jiupai6688 (Note to add and withdraw)
