| 摘要: | 小型電離層探測儀（Compact Ionosphere Probe, CIP），是由國立中央大學（National Central University, NCU）太空酬載實驗室（Space Payload Laboratory, SPL）研發與製作出的一個可現地量測（In-situ）太空電漿的儀器，收集衛星經過的電漿離子，轉化成封包數據提供我們做科學資料的分析。小型電離層探測儀的前身是福爾摩沙衛星五號（FORMOSAT-5）的科學酬載：先進電離層探測儀（Advanced Ionospheric Probe, AIP）的優化版，體積重量都減少了許多，為的是能將其安裝於立方衛星上，配合立方衛星本體在耗能、空間限制下仍不失其功能。隨著衛星任務的進展與需求，CIP也一次又一次的進行改良與優化，不論是在機構，又或是電路、功能上都有了大幅度的更新，也隨著積體電路製造技術的快速發展，越來越多合適的元件可以取代原先的設計，使其在電路上能夠以更精簡的方式實現。除此之外，在新式CIP當中，將新增儲存裝置，並針對CIP電路設計上需要改進的部分做系統性的優化，同時也把他的核心元件做一次統整性的更新，包含FPGA晶片全面升級，不但維持其低功耗、低成本的優勢，更能促進未來軟硬體的更高效開發。這確保了未來的衛星任務，例如福爾摩沙衛星九號（FORMOSAT-9）、珍珠號立方衛星（PEARL-1AB），可以更加方便地整合並運行。這篇論文將從電離層開始說起，介紹小型電離層探測儀在太空酬載實驗室上的歷史演進，介紹CIP最新的架構、功能、驗證，並展示模組化CIP在PEARL 1C立方衛星上、ELITE衛星測試上所展現出的成果。接著以福衛九號太空天氣探測儀（Space Weather Ionosphere Probe, SWIP）為例，說明SWIP最新的電路架構、功能、介面與韌體，展示小型電離層探測儀在未來能夠繼續為台灣的太空做出貢獻，使科學研究更有價值性。;The Compact Ionospheric Probe （CIP） is an in-situ instrument for measuring space plasma, developed and manufactured by the Space Payload Laboratory （SPL） at National Central University （NCU）. It gathers plasma ions from the areas where the satellite passes through, converting them into data packets for scientific analysis. The CIP is a miniaturized version of the Advanced Ionospheric Probe （AIP）, a science payload on the FORMOSAT-5. Its size and weight have been significantly reduced to allow installation on CubeSats, while still retaining the functionality to conform to the energy and space limitations. As the satellite mission requirements, the CIP has undergone continuous improvements and optimizations, including substantial updates in its structure, circuitry, and functionality. With advancements in integrated circuit manufacturing technologies, more suitable components are available to replace the original designs, fulfilling the functional requirements in a more streamlined manner. Additionally, the new generation of CIP incorporates enhanced storage capabilities and systematic optimizations will be undertaken to refine and enhance the identified shortcomings in the CIP circuitry design. Moreover, the core component, the FPGA chip, has also had a comprehensive upgrade, maintaining its advantages of low power consumption and cost-efficiency while facilitating more efficient hardware and software development in the future. These advancements ensure that future satellite missions, such as FORMOSAT-9 and PEARL-1AB, can be conveniently integrated and operated. This paper begins with an overview of the ionosphere and shows the historical evolution of the Compact Ionosphere Probe at the Space Payload Laboratory. It details the latest architecture, functions, and validations of the CIP and showcases its modular design′s performance in applications such as the PEARL-1C CubeSat and the ELITE satellite tests. Take the FORMOSAT-9 Space Weather Ionosphere Probe （SWIP） as an example, the paper also explains the latest circuit architecture of SWIP, functionality, interfaces, and firmware, demonstrating how the CIP continues contributing to Taiwan′s space exploration efforts. These contributions significantly enhance the scientific value of space research. |
