China used the Long March 2D carrier rocket at the Jiuquan Satellite Launch Center to successfully put the Gaofen-9 05 satellite into the scheduled orbit, and the launch was a complete success. The mission also carried and launched a multi-functional test satellite, Tiantuo-5 satellite.
Gaofen-9 05 is an optical remote sensing satellite with a ground pixel resolution of up to sub-meter level. It is mainly used in territorial surveys, urban planning, land right confirmation, road network design, crop yield estimation, disaster prevention and mitigation, etc. , Which can provide information guarantee for the construction of the "Belt and Road".
The multi-functional test satellite carried and launched will be developed by the Academy of Military Sciences, and will test and verify new technologies such as communications, navigation, and remote sensing in orbit; the Tiantuo-5 satellite will be developed by the National University of Defense Technology and will target ships, aircraft, and buoys in orbit. And the Internet of Things and other new information collection technologies are tested and verified.
