摘要:	飛鼠號衛星(IDEASSat)是由國家太空中心資助由中央大學與國際合作研發的教學立方衛星計畫。立方衛星本身相較於一般衛星其尺寸要小得非常多也較不複雜，導致製造時間與消耗成本也會低得多，因此是一個非常適合以教育為目的或由學術組織開發的衛星架構。衛星由許多的次系統(Subsystem)所構成，一般來說，衛星的次系統被分為: 主酬載(Main Payload)、衛星電腦指令控制系統(Command and Data Handling Subsystem, C& DH)、通訊次系統(Communication Subsystem, COMM)、電力次系統(Electrical Power Subsystem, EPS)以及姿態控制次系統(Attitude Determination and Control Subsystem, ADCS)。通訊次系統是負責對地的資料傳送與接收從地面發射的指令，因此與地面站的通訊時間與資料的正確程度會是主要考量。本論文將會集中於IDEASSat立方衛星的通訊次系統評估與設計，還有與其相對的通訊地面站的建置，希望總和這個計劃的經驗，以提供接下來的同仁做為學習及借鑒。 ;IDEASSat is a 3U CubeSat funded in part by the Taiwan National Space Organization and developed by National Central University in collaboration with international partners. The size and complexity of a CubeSat is much smaller than a typical satellite so that the manufacturing time and cost are much lower. These reasons make the CubeSat satellite architecture ideal for education purposes or for development in a university environment.. Like larger satellites, a CubeSat is made up of sub-systems including the Main Payload, Command and Data Handling Subsystem (C&DH), Communication Subsystem (COMM), Electrical Power Subsystem (EPS), and Attitude Determination and Control Subsystem (ADCS). Among those, COMM is responsible for transmitting data and receiving commands. Therefore, the amount of data that can be downlinked during access time between the satellite and the ground station, as well as the integrity of the data received will be the main considerations driving COMM subsystem design. This thesis will introduce and discuss the assessment and design of the COMM subsystem of IDEASSat and the corresponding ground station. We conclude with the lessons learned through the development of this project for reference in the design of future missions.
