The Sperti Astro-Compass Mk II is a rare World War II-era aircraft navigation instrument designed for celestial navigation in high-latitude regions where magnetic compasses become unreliable. Used by Allied aircrews during long-range operations, this precision-made astro-compass allowed navigators to determine true heading using the sun or stars—making it an essential tool for Arctic and transoceanic flight navigation.
Function: At high latitudes near the poles, magnetic compasses can become unstable or inaccurate due to Earth’s magnetic field geometry. Astro-compasses solved this problem by using celestial objects to establish directional reference, making them crucial for Arctic bomber and transport routes during WWII.
