Abstract:	飛鼠號立方衛星(IDEASSat)是一顆由台灣國家太空中心資助，由國立中央大學(NCU)開發的3U大小的立方衛星，其任務為對地球電離層進行現地量測，以量化電離層變化與小尺度的電離層不規則體。飛鼠號立方衛星已於2021年1月24日由SpaceX的Falcon 9 Block 5 (Transporter-1)發射成功，於2021年9月2日宣布退役，並於任務期間成功接收上傳的指令、下傳飛行資料，用以提供研究與未來任務的經驗學習。中央大學衛星地面站位於中央大學健雄館10樓，擁有UHF頻段上傳和下載能力與S頻段下載能力，主要提供IDEASSat與INSPIRE聯盟衛星，監測與操作使用。本論文將介紹與討論中央大學衛星地面站的設計與測試過程，主要包含通訊鏈路估算、通訊硬體選用、軟體無線電、衛星資料編碼與使用者介面的設計與軟體整合，以及地面站接收成果與IDEASSat和地面站在開發時遇到的挑戰與經驗學習。 ;The Ionospheric Dynamics Exploration and Attitude Subsystem Satellite (IDEASSat) is a 3U CubeSat which has been funded in part by the Taiwan National Space Organization (NSPO) and developed by National Central University (NCU), Taiwan. IDEASSat was developed to provide in-situ measurements of the Earth’s ionosphere to quantify ionospheric variability and irregularities. IDEASSat was successfully launched aboard the SpaceX Falcon 9 Block 5 launch vehicle (Transporter-1) on January 24th, 2021 and decommissioned on September 2nd, 2021. During the mission duration, IDEASSat received uplinked commands, and downlinked flight data successfully to provide information on the on-orbit performance of the spacecraft for evaluation and experience for future missions. The NCU satellite ground station is located on the 10th floor of the Chien-Shiung building. The NCU ground station has the capability to transmit in the UHF band and receive in the UHF band and S band, and provides control and monitoring services for spacecraft developed under the International Satellite Program in Research and Education (INSPIRE) consortium. The thesis will introduce and discuss the design and implementation of the NCU satellite ground station. The thesis includes the link budget, communication hardware, software defined radio (SDR), satellite telemetry and command coding, user interface design and integration, flight performance results of the NCU ground station, as well as the challenges and lessons learned in the development of the NCU ground station.
