The Sky Polarization Azimuth Sensing System, SkyPASS®, provides mission-critical, highly-accurate attitude information regardless of GPS accessibility in a low-power, low-cost, extremely small form factor.
SkyPASS finds North with less than 2-mil accuracy and has considerable military and commercial impact as a navigation, localization, and targeting aid. The system is passive, does not require time to initialize, and is well suited for air, land, sea, and weapon platforms.
