At 12:01 on August 6, Beijing time, China used the Long March 2D carrier rocket at the Jiuquan Satellite Launch Center to successfully put the Gaofen 9 04 satellite into the scheduled orbit. The launch was a complete success. The mission also carried and launched the Tsinghua Science Satellite.
Gaofen-904 is an optical remote sensing satellite with a ground pixel resolution of up to sub-meter level. It is mainly used for land surveys, urban planning, land right confirmation, road network design, crop yield estimation, and disaster prevention and mitigation. , Which can provide information guarantee for the construction of the "Belt and Road". The Tsinghua Scientific Satellites launched onboard are developed by Tsinghua University. Theories and technologies such as the design method of the on-orbit gravity satellite system and the precision orbital atmospheric density measurement method based on dual-frequency GPS will be carried out for flight verification.
