2025年5月9日，諾斯洛普·格魯曼公司（Northrop Grumman）宣布，其先進的慣性測量單元（IMU）技術已成功應用於高超音速飛行器的導航，無需依賴全球定位系統（GPS）。

該IMU系統於2024年12月和2025年3月搭載於Stratolaunch公司的Talon-A高超音速滑翔飛行器，進行了兩次試飛。這些飛行器能以5馬赫或更高的速度飛行，IMU系統在此極端條件下仍能準確計算飛行路徑，顯示出其在高動態環境中的可靠性。

諾斯洛普的IMU技術源自其太空導航系統，經過小型化和強化處理，以適應高超音速飛行的嚴苛條件。該技術的成功應用，標誌著在無GPS環境下導航的重大進展，對於提升高超音速武器和飛行器的自主性具有重要意義。

🔍 三個重要觀點

1. 提升高超音速飛行器的自主導航能力：IMU技術的成功應用，使飛行器在無GPS環境下仍能準確導航，增強了其在敵對環境中的生存能力。
2. 技術源自太空導航系統的轉化應用：諾斯洛普將其在太空導航領域的技術經驗，成功轉化為適用於高超音速飛行器的導航系統，展示了技術的靈活性和適應性。
3. 推動高超音速技術的發展與應用：該技術的成功測試，為未來高超音速武器和飛行器的發展提供了可靠的導航解決方案，對於國防科技的進步具有重要意義。 

Northrop Tests GPS-Free Navigation Tech for Hypersonic Vehicles

On May 9, 2025, Northrop Grumman announced the successful testing of its advanced Inertial Measurement Unit (IMU) technology, enabling hypersonic vehicles to navigate without relying on the Global Positioning System (GPS).

The IMU system was tested aboard Stratolaunch’s Talon-A hypersonic glide vehicles during two flights in December 2024 and March 2025. These vehicles, capable of speeds exceeding Mach 5, demonstrated that the IMU could accurately calculate flight paths under extreme conditions, showcasing its reliability in high-dynamic environments.

Derived from Northrop’s space navigation systems, the IMU has been miniaturized and ruggedized to withstand the harsh conditions of hypersonic flight. This advancement represents a significant step forward in autonomous navigation capabilities for hypersonic weapons and aircraft, particularly in GPS-denied environments.

🔍 Three Key Points 

1. Enhanced Autonomous Navigation for Hypersonic Vehicles: The successful application of IMU technology allows hypersonic vehicles to navigate accurately without GPS, improving their survivability in contested environments.
2. Adaptation of Space Navigation Technology: Northrop Grumman has effectively adapted its space navigation expertise to develop a robust IMU system suitable for the extreme conditions of hypersonic flight.
3. Advancement in Hypersonic Technology Development: This successful test provides a reliable navigation solution for future hypersonic weapons and aircraft, marking a significant milestone in defense technology advancement.
