Navigeerimisel orienteerumiseks on kasutatud taeva polarisatsiooni, nii kasutati Pfundi taevakompassi 1950. aastatel Maa magnetvälja pooluste lähedal navigeerimisel, kui päike ega tähed polnud nähtavad (nt päevase pilve või hämariku all).
Sky polarization has been used for orientation in navigation. The Pfund sky compass was used in the 1950s when navigating near the poles of the Earth's magnetic field when neither the sun nor stars were visible (e.g., under daytime cloud or twilight).
