Hong Kong University of Science and Technology (HKUST) start-up Stellerus Technology aims to be the world’s first provider of satellite-enabled three-dimensional wind data to help wind power, transport and insurance firms boost revenues, cut costs and manage risks, according to its founders.
Stellerus, founded in 2023 by the university’s academics, would leverage China’s cost competitiveness in satellite manufacturing to make global 3D wind data collection economically viable, said Su Hui, the chairwoman and co-founder.
3D wind data – wind direction and speed and their changes with altitude – is crucial for improving weather forecasting, especially severe climate events.
“After I came to Hong Kong, I realised the technology for implementing such a project in mainland China was quite developed and the cost would be much lower than overseas,” Su said. “In the US, such a satellite could cost US$100 million to build, compared with 20 million yuan [US$2.8 million] in China.”
Su, a hydraulic expert, joined the HKUST’s department of civil and environmental engineering in 2022 as chair professor. She was formerly a principal scientist and weather programme manager at the Jet Propulsion Laboratory at Nasa.
