摘要:	PEARL (Propagation Experiment using Kurz-Above-band Radio in Low earth orbit) -1A 與 1B 為兩顆 6U XL 大小立方衛星，由中央大學負責整合測試，立方衛星主要任務目標為在台灣上方進行太空與地面及衛星間通訊實驗。兩顆立方衛星上皆搭載三個酬載，分別為 Inter-Satellite Link (ISL)、Compact Ionospheric Probe (CIP)、Perovskite Solar Cell (PSC)。ISL 將使用 Ka 波段進行跨地平通訊實驗測試，以達成星間通訊與衛星對地通訊功能；CIP 則為中央大學太空酬載實驗室自製小型電離層探測儀酬載，可進行全球電離層電漿溫度、速度與密度探測；而 PSC 則由鈣鈦礦太陽能電池及其他太陽能電池組成，其透過量測太陽能電池在太空中的電流和電壓之間的關係曲線 (I-V curve)，驗證其太陽能電池的發電功率。為確保立方衛星能符合各酬載所需指向， PEARL-1A、PEARL-1B 使用的姿態判定與控制次系統 (Attitude Determination and Control Subsystem, ADCS) 為 CubeSpace 所生產之模組，透過 LabVIEW 整合亥姆霍茲線圈控制、太空環境模擬與 ADCS 通訊，進行地面硬體迴路測試，以了解實際衛星在軌指向變化，以及模擬在軌磁力計校正等測試。;PEARL (Propagation Experiment using Kurz-Above-band Radio in Low earth orbit) -1A and PEARL-1B are two 6U XL CubeSats integrated by National Central University (NCU). Their main purpose is to perform space -to-earth and inter-satellite radio propagation channel experiments. Each CubeSat is equipped with three payloads, an Inter-Satellite Link (ISL) payload, a Compact Ionospheric Probe (CIP), and a Perovskite Solar Cell (PSC) payload. The ISL enables over-the-horizon radio communication experiments, utilizing the Ka-band for both inter-satellite communication and space-to-ground communications. The CIP is an all-in-one in-situ ion sensor developed by NCU to measure global ionospheric ion concentration, velocity, and temperature especially to monitor ionospheric plasma irregularities resulted in radio scintillations. The PSC consists of perovskite solar cells designed to verify power efficiency by measuring their characteristics of I-V curves in space. Depending on the pointing requirements of the payloads, PEARL-1A and PEAR-1B using CubeSpace ADCS modules as their Attitude Determination and Control Subsystem (ADCS). To verify that the ADCS meets mission requirements, we use LabVIEW to control Helmholtz coil for space magnetic environments and communicate with ADCS. Through these setups, we test ADCS control performance in different operating modes and simulation CubeSats behavior in orbit.
