The U.S. military relies upon GPS for navigation, weapons targeting and situational awareness. However, this reliance bears the risk of information being denied or spoofed by enemy forces or simply unavailable. Polaris offers SkyPASS as an azimuth sensor that does not rely upon GPS information. Instead, SkyPASS derives information from a natural phenomenon—the pattern of polarization in skylight. SkyPASS is less expensive and more accurate than other methods for measuring absolute roll, pitch and yaw. As one element in a system of systems that provides navigation information, SkyPASS can serve as a verification method for other systems and can serve as a primary technology when GPS data are degraded or denied.
