隨著立方衛星任務與搭載科學酬載的多樣化，地面操控系統的需求逐漸從單 純的資料接收，擴展至即時解析、狀態監控與硬體控制等整合性操作。考量到現有 通用型開源地面站軟體在應對特定任務的客製化通訊協定與保護機制時，往往需 要較高的整合成本，本研究針對國立中央大學參與之兩項立方衛星任務——旺來 衛星（ONGLAISat）與鯨鯊號（SCION-X），開發符合其任務需求與具備防錯機制 之專屬地面飛控軟體。 針對衛星任務的不同規範，本研究實作了兩套獨立系統：ONGLAISat飛控軟 體以MATLAB為平台，作為備援接收系統，處理遵循CCSDS標準之三層封包遙 測解析；SCION-X飛控軟體則以C#為開發環境，透過TCP網路介面與GNU Radio 軟體定義無線電連接，處理基於AX.25(Amateur X.25)協定之雙向通訊。為了提升 系統維護性並減少編碼的限制，SCION-X系統運用資料驅動架構，利用外部CSV 與 JSON 設定檔執行位元級封包擷取與物理量映射，使軟體能在無需重新編譯程 式碼的情況下，配合任務迭代彈性調整遙測資料。 在任務操作支援方面，本研究於軟體中實作了基於衛星運行模式的健康監控 邏輯。系統可參照衛星當前之運行模式與各次系統安全閾值，動態切換圖形化介面 之警告燈號與參數顏色警示，並結合LINE Notify推播異常資訊，有效提升整體自 動化及即時狀態確認能力，並支援操控室外的遠端監控。此外，遙控指令發射端整 合了佇列管理功能，並加入射頻硬體時序控制，以降低地面站大功率放大器在操作 過程中的損壞風險。 本研究期能透過此次雙任務的軟體開發與系統整合經驗，作為未來國內學術 界與產業界在小型衛星地面系統開發上之具體工程實踐參考。;With the increasing complexity of CubeSat missions， ground control system requirements have evolved from simple data reception to integrated platforms encompassing real-time decoding， situational awareness， and hardware safety control. Since existing open-source ground station software lacks the flexibility to accommodate mission-specific protocols and hardware protection needs， this study develops dedicated ground control software for two CubeSat missions at National Central University: ONGLAISat and SCION-X. Two independent systems were implemented. The ONGLAISat software， built on MATLAB， serves as a backup receiving system implementing a CCSDS-compliant three layer packet decoding architecture. The SCION-X software， developed in C#， interfaces with a GNU Radio SDR chain via TCP to achieve bidirectional AX.25-based communication. To eliminate hardcoded limitations， the SCION-X system adopts a Data Driven architecture using external CSV and JSON configuration files for bit-level packet extraction and physical quantity mapping， enabling telemetry format updates without source code modification. For operational safety， a context-aware health-monitoring engine dynamically cross references the satellite′s operating mode against subsystem safety thresholds to update GUI warning indicators， and LINE Notify push alerts support remote monitoring. The command uplink module integrates sequential queue management and RF Hardware Interlock timing control to protect ground station amplifiers during transmission. This study successfully delivered two ground control platforms integrating real-time monitoring， historical trend analysis， and hardware protection， providing a concrete engineering reference for future small satellite ground system development.
