Robert C. Byrd Green Bank Telescope (Current)

The present-day Robert C. Byrd Green Bank Telescope is shown in a strict orthographic elevation with its asymmetric reflector pointing at the zenith. Its off-axis reflector is a physical 110 m by 100 m section that provides a 100 m effective projected aperture, while the structure reaches about 148 m from its base to the top of the feed arm. The image is scaled uniformly from the documented 110 m reflector-section span rather than reshaped to fit a bounding box.

Measurement basis

Uniform scale is anchored to the documented 110 m physical reflector-section span. The 100 m effective projected aperture and 148 m base-to-feed-arm height remain independent checks and do not deform the elevation artwork.
