Stereoscopic photographs were taken of several models of the Echo II satellite using the Wild Stereometric camera. Large and small scale work was accomplished on the Wild Autograph A7, including contour maps and coordinate readout. Data were processed to achieve final results which included cross sections, radii of curvature, deviations from best-fitting spheres, and distances above a one-meter chord. Author
