ASTRADIA, the daytime star viewfinder for a safe and robust navigation system!
After several years of research and development, Sodern has developed Astradia, an endoatmospheric celestial viewfinder that, coupled with an inertial power plant, provides day and night an attitude measurement to guarantee accurate, robust and reliable on-board geolocation information.
This high-performance sight is therefore autonomous, not dependent on radio navigation signals and aims to counter the natural drift of inertial power plants. In addition, it has the advantage of not emitting any wave that would make the carrier detectable.
Leave it to the French to announce their technology with an exclamation point, but like I’ve been saying, we need an alternative to satellite-based navigation systems!
