PROJECT & FUNDING SCHEMES

Low Earth Orbit (LEO) satellites have attracted attention in recent years in various fields, e.g., national security, and commercial applications. The construction of the nextgeneration Chinese Beidou Navigation Satellite System puts insight into LEO
development. Meanwhile, driven by the Hong Kong Government's 2025 Policy Address promoting aerospace science and technology development, Hong Kong is exploring streamlined procedures for vetting license applications for operating LEO satellites, positioning LEO as a new strategic trend in global satellite development. This project aligns perfectly with these policy directions by developing a real-time POD and timing software for LEO satellites, as well as a hardware processing platform and an integrated on-board system in LEO missions. Precise orbit and time information for onboard LEO satellites are important in LEO-related applications. However, real-time LEO precise orbit determination (POD) and timing are still challenging, limiting LEO real-time applications in which quick data is required. The platform developed in this project would significantly
enhance LEO capabilities in positioning, navigation, and time, and expand the LEO realtime applications such as remote sensing of the environment, weather forecasting, disaster management, etc. Moreover, it will also drive breakthroughs in Hong Kong's satellite technology and promote industry growth in fields like smart cities and intelligent transportation.
