One other Chinese language Gaofen Earth-imaging satellite tv for pc launched Sunday aboard a Lengthy March 2D rocket, using to house with a pair of experimental rideshare payloads for the Chinese language navy.

The fifth in a sequence of Gaofen 9 Earth commentary satellites lifted off at 0227 GMT Sunday (10:27 p.m. EDT Saturday) atop a liquid-fueled Lengthy March 2D rocket from the Jiuquan house base within the Gobi Desert of northwestern China, in line with Chinese language state media.

The brand new satellite tv for pc — designated Gaofen 9-05 — “can be primarily used for land surveys, metropolis planning, land proper affirmation, highway community design, crop yield estimation and catastrophe prevention and mitigation,” China’s state-run Xinhua information company stated.

The outline matches info printed about earlier satellites within the Gaofen 9 sequence.

Earlier Gaofen 9 satellites launched in 2015 and on Could 31, June 17 and Aug. 6 of this yr.

The 173-pound (78.5-kilogram) Tiantuo 5 spacecraft will take a look at applied sciences to gather information on maritime and aviation visitors, automated information assortment, and a brand new electrical propulsion system for small satellites, in line with the college’s web site.

The opposite small satellite tv for pc launched by the Lengthy March 2D rocket was a “multifunctional take a look at satellite tv for pc” developed by the Academy of Army Science, a analysis institute of the Folks’s Liberation Military.
