本論文電子物理特性量測酬載目的為開發能夠量取電離層的電子溫度及電子濃度，並且設計體型小、能放置在立方衛星上的量測酬載。針對體積小的立方衛星考量到量測酬載的酬載之於探針接觸大氣之表面積比例小，所造成探針量測電漿特性I-V曲線扭曲的現象，本論文藉由等效電路模擬呈現酬載之於探針不同表面積比例對於I-V曲線扭曲的程度。為更深入探討表面積比影響，也將設計提高量測酬載之取樣頻率。本量測酬載設計為實驗室研發的ASA介面，內建C語言函式庫，讓使用者能夠更簡易使用及維護此量測酬載。;The cube satellite payload in this research paper is developed for measuring electron temperature and density in ionosphere which is aim to be installed on a Cube satellite. As for small size-featured, the study present what the ratio of the probe surface area to the payload surface area impact on the I-V characteristic curve. Also, we show the different ratio of surface area and I-V characteristic distortion degree by simulation of equivalent circuit. And upgrading the sample frequency of payload to aid for doing more ratio of surface area problem experiment on payload. A special design on the payload is to provide call function which is built in ASA system, C language based, which developed by our lab. The design makes the use and maintenance of the payload easier.
