First Step in Building Satellite Constellation
Contributing to National Development in Remote Sensing Technology
HONG KONG, Aug. 21, 2023 /PRNewswire/ — The Hong Kong University of Science and Technology (HKUST) announced today that it will launch a multispectral optical satellite at the Jiuquan Satellite Launch Center in Gansu with Chang Guang Satellite Technology Company Ltd (Chang Guang) this Friday (August 25). The satellite “HKUST-FYBB#1” will be used for tracking remote sensing data related to the global environment, disaster, and sustainable development. As the first university in Hong Kong to initiate a satellite mission, the launch also marks HKUST's first step towards building a remote sensing satellite constellation and a comprehensive environmental monitoring and disaster forecasting system.
The multispectral optical satellite set to be launched on August 25 for research purposes is the most advanced type in the realm of civilian satellites. The spatial resolution of the remote sensing images it collects is 0.5 meters, which is 20 times higher than the openly accessible data of images taken from the European Space Agency's Sentinel-2 optical satellite. Its swath of image is over 150 kilometers, comparable to those of the latest generation of the United States' land satellites.
As an expression of gratitude to Mr. Francis YIP Chi-Hung and his wife, Mrs. Catherine YIP NG Bun-Bun, for their generous donation and support for the launch, the satellite is named “HKUST-FYBB#1”. HKUST will first use the data collected by the satellite to establish a digital twin system that covers all slopes in Hong Kong for the monitoring of their surface conditions, as well as the simulation and show of the process of landslide disasters and societal responses to emergencies. This is done in the hope of enhancing coordination and decision-making in disaster response and management.
HKUST signed an agreement earlier with Chang Guang, the first commercial remote sensing satellite company in Mainland China. Apart from the launching of “HKUST-FYBB#1”, HKUST and Chang Guang will venture into a long-term, extensive and multi-facet collaboration in satellite research and development for carbon emission and its data application.
Combining HKUST's scientific research capability and achievements in meteorology, oceanography, and environmental protection, as well as remote sensing data obtained from Chang Guang's 108 orbiting satellites, which form the world's largest sub-meter level commercial remote sensing satellite constellation “JiLin-1″, the parties are set to build a comprehensive environmental monitoring and disaster forecasting system. The system aims to provide scientific data in support of the nation's dual carbon policy goals, namely peaking carbon emissions by 2030 and achieving carbon neutrality by 2060. It also seeks to enhance the country's remote sensing technology – a cutting-edge technique involving the collection of electromagnetic radiation information from space or higher altitudes on Earth's surface, as well as the processing and imaging of such data for the identification and understanding of the Earth's environment and resources.
Rendering their full support to the satellite launch, Mr. Francis YIP and Mrs. Catherine YIP said they were delighted to facilitate the strategic cooperation between HKUST and Chang Guang. They stated, “We have seen HKUST's indefatigable effort and determination in promoting the development of aerospace technology in Hong Kong. We will continue to support HKUST and the innovation and technology development in Hong Kong. This project marks an important milestone in Hong Kong's aerospace development. As Hongkongers, we feel proud of our city's progress and are deeply honored to contribute to this project. We would also like to express our gratitude to Prof. LIU Yuyi for inscribing the name of the satellite in calligraphy.”
HKUST Council Chairman Prof. Harry SHUM said, “HKUST is a staunch supporter of sustainable development and has always been active in exploring and finding solutions to global carbon emissions problems. In the face of the pressing challenge of climate change, we are deeply thankful to Mr. and Mrs. Yip for their support, which allows us to commence our remote sensing satellite program. We look forward to cooperation with the government, research institutes, enterprises, and different sectors for the wider application of the data we will obtain through our cooperation with Chang Guang. Together, we can make contributions to the nation's dual carbon policy goals, our government's carbon emissions targets, and the easing of global climate change to demonstrate our commitment to sustainable development.”
HKUST President Prof. Nancy IP also expressed her gratitude to Mr. and Mrs. Yip. She said, “HKUST strongly encourages our researchers to engage in exploratory, socially impactful frontier research projects, and to actively work with industry partners to actualize scientific discoveries to address global challenges such as natural disasters and climate change. We are excited to partner with Chang Guang to drive aerospace innovation and contribute to the national development strategy. HKUST will fully leverage its research capabilities and continue to promote cooperation among various academic, research, and industry sectors to strengthen our aerospace industry and achieve the nation's dual carbon policy goals.”
Chang Guang Deputy General Manager Mr. CHEN Maosheng said, “The strategic cooperation agreement signed between HKUST and us aims to foster deep collaboration in the fields of scientific satellite development and remote sensing data application. Leveraging our research and development ability in satellite manufacturing and combining it with the remote sensing application expertise of HKUST, the two parties will jointly develop greenhouse gas remote sensing monitoring satellites. We will continue to engage in extensive cooperation in the field of new remote sensing satellites, promoting the joint development of the aerospace industry in Mainland and Hong Kong, and enhancing the remote sensing data service capabilities in Hong Kong and the Greater Bay Area.”
HKUST Vice-President for Institutional Advancement Prof. WANG Yang, the driving force behind the plan, emphasized, “This satellite launch marks the initial step towards HKUST's ambitious goal of building a comprehensive remote sensing satellite constellation. Our aim is to develop cutting-edge multimodal spatial remote sensing technologies, including novel carbon monitoring techniques and data analysis tools. With comprehensive sensing capabilities, we envision providing services for disaster management, smart city development, and sustainable resource management. This initiative will benefit the Greater Bay Area and the nation, aligning with the national dual-carbon strategic goal and leading the development of environmental monitoring satellite remote sensing technology. Our ultimate aim is to contribute to sustainable development domestically and globally.”
The HKUST research team is led by Prof. Su Hui, who joined the University last year through the Global STEM Professorship Scheme, and Prof. ZHANG Limin, Head and Chair Professor of HKUST's Department of Civil and Environmental Engineering. The team will work with their counterparts at Chang Guang to develop high-resolution optical satellites and key technologies for monitoring carbon emissions. The two teams will lead the development of remote sensing technology in environmental monitoring satellites, providing scientific data for macro-level decision-making on areas such as energy conservation, emission reduction, and achieving the national dual-carbon strategic goal.
