虹科汽車 GNSS 仿真測試方案
行業發展與背景
近年來，智能網聯汽車的發展方向愈加清晰，技術演進亦持續深化，並展現出巨大的市場潛力。現階段，行業已基本形成「感知－通訊－規劃控制」的核心技術架構。其中，GNSS 定位作為感知層的關鍵組成部分，是目前唯一可提供絕對位置資訊的感測方式。
在遠端車控、智能座艙、車內娛樂系統、V2X Box、高精度定位，以及 V2X 路側單元（RSU）等典型應用中，均需要依賴高精度 GNSS 定位模組。因此，市場對 GNSS 定位的準確性、穩定性與可驗證性要求亦不斷提高。
GNSS 測試現狀及挑戰
目前常見的 GNSS 測試方法主要包括三類：
- 借助真實環境中的 GNSS 訊號進行測試（Live Sky）
- 錄製 GNSS 訊號並回放進行測試（RF Record / Playback）
- 透過軟體或硬體進行 GNSS 訊號仿真與測試（Simulation）
| 測試方式 | 真實天空訊號 | 訊號錄製 / 回放 | 訊號仿真 / 模擬 |
|---|---|---|---|
| 可重複測試 | × | √ | √ |
| 可控環境條件 | × | 部分 | √ |
| 可於任意時間、任意地點進行 | × | × | √ |
| 可模擬未來訊號與事件 | × | × | √ |
| 可模擬真實訊號 | √ | √ | 部分 |
目前市面上大部分 GNSS 模擬設備仍存在以下問題：
- 更新迭代能力不足
- 軟體操作複雜，學習週期較長
- 傳統硬體成本高昂
- 選件繁多且需額外付費
- HIL 仿真延遲偏高
智能網聯 GNSS 測試需求
高性能、高開放性及高性價比的測試方案
一方面，智能網聯汽車需對各類 GNSS 接收器進行性能測試，且往往涉及大批量驗證，因此測試系統必須具備良好的可重複性、可控性、易用性與成本效益。
另一方面，在智能網聯應用中，GNSS 往往需要與其他模組共同進行在環仿真（HIL）測試。這要求測試平台具備接近即時的處理能力、低延遲表現，以及靈活的嵌入與整合能力，同時亦需兼顧未來升級與擴展需求。
