"Tianzhi-2D" satellite was launched, and the types of satellites are as follows

China Science and Technology News Network, January 16 (Xu Qiqi) At 11:14 on January 15, the Long March 2 Dingyao 71 carrier rocket successfully launched the Qilu-2, Qilu-3, Luojia-3 01, Golden Bauhinia Satellites 3, 4, 6, Jilin-1 MF02A 03, 04, 07, Gaofen 03D 34, Haihe-1, Wolfman, Beiyou-1, and Tianzhi-2D satellites into the predetermined orbit at the Taiyuan Satellite Launch Center, and the launch mission was a complete success.

Artificial satellites are unmanned spacecraft orbiting the Earth or other planets. Artificial satellites can be divided into three categories: scientific satellites, application satellites and technical test satellites.

Scientific satellites are satellites used for scientific exploration and research. They can study and detect the atmosphere, radiation belts, magnetosphere, cosmic rays, solar radiation, etc. of a planet. The satellites are equipped with various detection instruments. Through the data collected by scientific satellites, humans can better understand the universe.

The mission of application satellites is to provide practical business applications on the ground. There are many types of application satellites, mainly including navigation satellites, communication satellites, and observation satellites, which can be subdivided into more than ten types.

A technology test satellite is a satellite that tests new technologies or conducts tests for application satellites. Some countries will test some new or complex technologies on application satellites on technology test satellites, and then use them on application satellites after they are successful. The content of technology test satellite tests is very wide, including manned spacecraft life support systems, rendezvous and docking tests, mobile communication tests, etc.

Satellites are now on the road to becoming more intelligent. According to Science and Technology Daily, the Tianzhi-2D satellite has realized full deployment on a unified micro-cloud computing platform for the first time, which in turn drives intelligent scheduling and computing, and no longer has separate satellite services, attitude control, data management and other subsystems. The Tianzhi software stack with an open system architecture makes it highly open.
