Japanese satellite company
iQPS (Institute for Q-shu Pioneers of Space, Inc.) is a Japanese satellite manufacturer and operator. The company was founded as a spin-off company of Kyushu University in 2005.[1] As of November 2023, the company operated three Earth observation satellites, each equipped with a synthetic-aperture radar (SAR).[2]
iQPS was founded by Tetsuo Yasaka, Noboru Sakurai and Kunihiro Funakoshi in 2005 to promote the space industry in Kyushu. By 2013, with its members aging, the trio were considering to close the company when Shunsuke Onishi, then a graduate student studying at Kyushu University approached them intending to join iQPS. Onishi was hired on two conditions: that he become the company’s CEO, and that he come up with a viable business plan. Onishi’s idea was to build small SAR satellites and conduct real time observation of Earth.[3]
The company’s first satellite, IZANAGI was successfully launched by a PSLV rocket in 2019.[4]
