平板衛星實驗平台在立方衛星開發中扮演重要的角色，其模組化架構可用於系統整合與功能驗證，亦能模擬在軌衛星任務流程，並具備衛星系統工程教育實作以及開源擴充等優勢。本研究以國內電腦廠商開發之平板衛星實驗平台為基礎，針對衛星電腦、電力子系統、遙測、追蹤與指令子系統以及感測器子系統等，設計實驗並進行功能驗證與整合測試，確保各模組間通訊協同與整體效能。
在此基礎上，將一通訊模組擴充至平板衛星上，進行硬體與韌體的整合，並與大學太空工程聯盟所開發的動手實作技術進展教育計畫衛星平台建立遙測與遙控的雙向通訊，模擬兩顆衛星之間的小型星座運作情境，重現星間鏈路中指令下達與數據回傳流程。接著依據前面建立的實驗流程，基於平板衛星實驗平台設計立方衛星任務腳本，涵蓋任務定義、指令執行與資料回傳等環節，進行完整在軌任務模擬。
最後，採用 Pyboard 開發板作為一節點建立太空區域控制網路及實作其所定義的服務，並針對此平板衛星實驗平台應用其服務。基於此平台設計的實驗與應用不僅能呈現立方衛星系統整合與通訊機制，且具有重複性與模組化特性，可作為大學或研究機構之太空系統工程課程教學參考。

The FlatSat experimental platform plays a vital role in CubeSat development. Its modular architecture not only facilitates system integration and functional verification but also enables on-orbit mission simulation, offering hands-on satellite systems engineering education and open-source extensibility. In this study, we build a FlatSat platform based on a domestic computer manufacturer to design experiments for the On-Board Computer (OBC), Eletrical Power Subsystem (EPS), Telemetry, Tracking & Command (TT&C) subsystem, and sensor system. Functional validation and integration tests are performed to ensure seamless communication and overall performance across all modules.
Building on this foundation, we integrate a communication module into the FlatSat platform, aligning both hardware and firmware, and establish bidirectional TC/TM links with the HEPTA-Sat educational platform developed by the University Space Engineering Consortium (UNISEC). This setup emulates a miniature two-satellite constellation, recreating the inter-satellite command uplink and data downlink processes. Next, following our previously defined experimental workflow, we develop mission scripts on the FlatSat platform that encompass mission definition, command execution, and data retrieval, and carry out a complete on-orbit mission simulation.
Finally, a Pyboard development board is used as a node to establish a SpaceCAN network and implement its defined services tailored to the FlatSat platform. The experiments and applications designed on this platform not only demonstrate CubeSat system integration and communication mechanisms but also offer repeatability and modularity, making it an valuable reference for space systems engineering courses at university and research institutes.
