Abstract

See full text

A device and method for estimating the elevation angle of one or more objects surrounding a user terminal include a convex image-reflecting surface, a transparent sighting surface disposed above the convex image-reflecting surface, and an elevation limit marking formed on or in the sighting surface. The elevation limit marking generates a reflected image in the convex image-reflecting surface that defines an elevation angle above a horizon of the earth that the one or more objects in a field of view of the convex image-reflecting surface must remain below so that the user terminal has an unobstructed view of the sky in all azimuthal directions.
