SAT-NET 2025

On October 28, the Second International Conference on Satellite Internet (SAT-NET 2025) officially opened at the Xidian University Hangzhou Research Institute. Renowned experts, scholars, industry leaders, and researchers from around the world gathered in Hangzhou to exchange cutting-edge insights and explore the future of satellite internet. Centered on key themes such as communications, network architecture, security, and service applications, the conference showcases the latest research breakthroughs while charting new pathways for technological innovation and industry development.

Yang Weidong, Director of the Satellite Internet Research Institute at the Xidian University Hangzhou Research Institute, delivered a welcome address on behalf of the organizers. He emphasized that the conference is dedicated to fostering an open and collaborative academic ecosystem, bringing together global intelligence through this international platform to jointly tackle the technical challenges of low-Earth-orbit constellation deployment and integrated space–air–ground networking, while accelerating the sustainable growth of an innovation-driven industry ecosystem.

Professor He Pinhan of the University of Waterloo, Canada, Chair of the Conference, noted that satellite internet is entering a pivotal transition from technological validation to large-scale, real-world deployment. He highlighted that this year’s conference will spotlight critical challenges in system architecture, transmission technologies, and service applications, serving as a high-impact platform to drive in-depth academic exchange and forge meaningful, results-oriented collaboration between research and industry.

This year’s SAT-NET Conference spotlights a range of frontier topics, including low-Earth-orbit (LEO) constellation deployment, integrated space–ground networking, communications security, satellite-based Internet of Things (IoT), and terahertz space–air–ground communications. Among the highlights, Professor Jiang Xiaohong of Future University Hakodate, Japan, delivered a keynote on “Covert Communications in Space–Ground Systems”; Professor Yu Jianjun of Fudan University and Principal Investigator at the Xidian University Hangzhou Research Institute presented “Recent Advances in Long-Distance Terahertz Space–Air–Ground Communications”; and Peng Xin, Vice General Manager of Taizhou Starlink Intelligence Technology Co., Ltd., shared insights in “Satellite IoT Technologies and Their Scalable Applications.”

Scholars and industry representatives, including Professor Peng Limei of Kyungpook National University, South Korea, and Professor Wu Zhenqiang of Shaanxi Normal University, led focused discussions across key segments of the satellite internet ecosystem, fostering in-depth dialogue and cross-sector collaboration on emerging technologies and applications.
