ICGPSRO 為全球 GNSS 掩星與遙測領域的重要國際會議，2025 年由成功大學夏漢民太空科技中心（HMSSTC）、中央大學全球太空觀測與資料處理中心（GAODARC）共同主辦，成大、中央大學、國家太空中心（TASA）及美國大氣科學研究大學聯盟（UCAR）合力策劃，是臺灣少數以太空科學為主題、連結國際學術社群的盛會。
國家太空中心（TASA）吳宗信主任致詞
研討會主題涵蓋電離層變化、數值天氣預報資料同化、GNSS-R 海面風場觀測及次世代衛星任務應用等關鍵議題。會中國際太空與大氣科學領域的專家分享 GNSS 遙測技術創新、太空天氣監測資料應用及氣候觀測前瞻發展的最新成果。
成大研發長劉全璞
除專題演講與技術論壇外，大會亦設有海報展示與青年學者論壇，提供年輕研究人員與國際專家面對面交流的機會。期望藉由多元互動，培育具備 GNSS 觀測、資料分析與模式應用能力的新世代科研人才，推動我國太空科學持續向前發展。
成大副國際長張巍勳
自「福衛三號」與「福衛七號」任務以來，臺灣長期在全球掩星觀測領域扮演關鍵角色，提供全球最多的觀測資料，對氣象預報與太空天氣監測貢獻卓著。
成大團隊在兩項任務中皆扮演核心角色—福衛三號時期即參與電離層資料分析與太空天氣預報模式研發，並於福衛七號任務中率先以掩星觀測揭示南極平流層暖化引發低緯度電離層異常震盪的現象，研究成果刊登於國際頂尖期刊《Geophysical Research Letters》。
中央大學劉正彥教授
成大夏漢民太空科技中心近年積極投入衛星研發與太空觀測研究，致力推動跨領域整合與國際合作，逐步建立我國太空科研的重要推動能量。本次會議結合國內太空研究單位與國際專業組織，打造兼具科學探討與技術合作的平台。藉由此此 ICGPSRO 國際研討會，成大持續拓展太空科學的國際影響力，深化臺灣與全球研究機構的合作連結，並推動新一代衛星觀測與太空遙測任務的發展。

The 7th International Conference on GPS Radio Occultation (ICGPSRO) was held from October 28 to 30 at Wanghong Hall, Cheng Kung Campus, National Cheng Kung University (NCKU). Leading experts and scholars from the United States, Europe, Japan, and other top research institutions gathered to discuss the latest advances in Global Navigation Satellite System (GNSS) radio occultation and reflection remote sensing technologies (GNSS-RO/R) for meteorology, climate, and space weather research. Through these academic exchanges, the conference aimed to enhance the global research community’s understanding of Taiwan’s contributions to occultation observations and space weather research, while strengthening Taiwan’s international scientific presence.

ICGPSRO is a major international conference in the field of GNSS occultation and remote sensing. In 2025, it was co-hosted by National Cheng Kung University’s Han-Min Hsia Summer Space Science and Technology Center (HMSSTC, 成大夏漢民太空科技中心) and National Central University’s Global Atmospheric Observation and Data Application Research Center (GAODARC, 中央大學全球大氣觀測與資料應用研究中心), with planning support from NCKU, National Central University, the National Space Organization (NSPO/TASA, 國家太空中心), and the University Corporation for Atmospheric Research (UCAR, 美國大氣科學研究大學聯盟). This conference is one of the few Taiwan-based international gatherings focused on space science that connects the global academic community.
Opening Remarks by Tsung-Hsin Wu (吳宗信), Director of the National Space Organization (TASA)
The three-day conference covered key topics including ionospheric variations, numerical weather prediction data assimilation, GNSS-R ocean surface wind observations, and applications for next-generation satellite missions. International experts in space and atmospheric sciences shared the latest innovations in GNSS remote sensing, applications of space weather monitoring data, and forward-looking developments in climate observations.
NCKU Dean of Research & Development Department Chuan-Pu Liu (劉全璞)
In addition to keynote speeches and technical forums, ICGPSRO featured poster sessions and a Young Researchers Forum, providing opportunities for early-career scientists to engage directly with international experts. Through these interactions, the conference aimed to cultivate a new generation of researchers proficient in GNSS observations, data analysis, and modeling applications, further advancing Taiwan’s space science capabilities.
NCKU Deputy Vice President for International Affairs Wei-Hsun Chang (張巍勳)
Since the FORMOSAT-3 and FORMOSAT-7 missions, Taiwan has played a critical role in global occultation observations, providing some of the world’s most extensive datasets and making significant contributions to weather forecasting and space weather monitoring.
The NCKU team has been central to both missions. During the FORMOSAT-3 mission, they contributed to ionospheric data analysis and the development of space weather prediction models. In the FORMOSAT-7 mission, they were the first to reveal low-latitude ionospheric oscillations triggered by stratospheric warming over Antarctica through occultation observations. The findings were published in the top international journal Geophysical Research Letters.
Professor Cheng-Yen Liu (劉正彥), National Central University
In recent years, NCKU’s Han-Min Hsia Summer Space Science and Technology Center (HMSSTC, 成大夏漢民太空科技中心) has actively engaged in satellite development and space observation research. The center promotes interdisciplinary integration and international collaboration, gradually establishing Taiwan’s key capabilities in space science. This conference brought together domestic space research institutions and international professional organizations to create a platform for both scientific discussion and technical cooperation.
Through the 2025 ICGPSRO, NCKU continues to expand its international influence in space science, deepen Taiwan’s collaboration with global research institutions, and advance the development of next-generation satellite observation and space remote sensing missions.
