What does it mean to launch a remote sensing satellite?

China's space industry is getting better and better, and it has made good achievements in various fields. Recently, Billie Billie plans to launch a remote sensing satellite. Do you know what remote sensing satellite means? Then let the constellation knowledge reveal the secret for everyone!

Miley Miley plans to launch a remote sensing satellite. Billie Billie plans to launch a remote sensing satellite named "Bi Li Bi Li Video Satellite" in late June this year. Remote sensing video and picture data obtained by satellite will be used for popular science work. Bili Bili is a highly concentrated cultural community and video platform for young people in China. The contents of popular science dissemination and knowledge sharing in the station are deeply loved by young netizens in China. The staff told reporters that the video satellite is like an "eye" to see the world from space. It will look down on the earth in a sun-synchronous orbit more than 500 kilometers from the ground, and it can circle the earth 15 times a day. Satellite has the function of three-dimensional imaging, which can realize high-precision remote sensing observation of the earth, capture the dim light of the city at night, observe the change of the aurora of the earth, and also observe space celestial bodies such as the moon and Saturn. At present, the official account of "Mile Mile Video Satellite" has been officially launched in Mile Mile, and the whole process of satellite launch will be broadcast exclusively in late June. In the future, popular science videos will be regularly updated based on massive remote sensing videos and picture data taken by satellites, covering science and technology, humanities, history, earth, public welfare, education and other fields. And customize the shooting task for users, and take aerial photos of the beautiful earth with satellites.

This satellite has inherited the mature stand-alone and technical foundation of the "Jilin No.1" series of domestic satellites, adopted a self-developed large-format high-resolution camera, a wide-field night light camera and a new generation of high-speed storage system, and has the functions of high-resolution imaging, sports video shooting, celestial and aurora photography, night light remote sensing and so on. According to the staff of Changguang Satellite, the video satellite weighs about 172kg and is equipped with two high-performance load cameras. The main load camera can obtain ultra-high definition color video with resolution better than 0.92m and width greater than 1 1km×9km, and the sub-load night vision remote sensing camera can obtain night vision remote sensing images with resolution better than 50m and width greater than 200km. After the satellite is put into orbit, it will be networked with the previously launched 16 "Jilin No.1" satellite to enhance the multi-dimensional remote sensing information acquisition ability of the constellation and play a role in emergency safety, disaster prevention and mitigation, urban construction and other fields. It is reported that the video satellite was sent to Jiuquan Satellite Launch Center on May 1 1 this year. At present, the test preparation before satellite launch is progressing smoothly.

What does remote sensing satellite mean? Remote sensing satellite is an artificial satellite used as a remote sensing platform for outer space. Satellite-based remote sensing technology is called satellite remote sensing. Usually, remote sensing satellites can run in orbit for several years. Satellite orbit can be determined according to needs. Remote sensing satellites can cover the whole earth or any designated area within a specified time. When it runs in geosynchronous orbit, it can continuously remotely sense the designated area on the earth's surface. All remote sensing satellites need a remote sensing satellite ground station. Satellite data obtained from remote sensing market platform can monitor agriculture, forestry, ocean, land, environmental protection and meteorology. There are three kinds of remote sensing satellites: meteorological satellites, land satellites and ocean satellites.
