The Australian SKA Pathfinder ratio telescope (ASKAP) comprises an array of up to 45 dish antennas with diameter of 12 meters. ASKAP is situated at Australia's candidate site for the International Square Kilometre Array telescope in Western Australia. It is intended to be a fully-functional radio telescope, with a science case based on its wide-field-of-view capabilities at centimeter wavelengths. The paper reports the photogrammetric measurement of the first ASKAP antenna reflector surface. Deformation of the reflector surface was measured with photogrammetric system V-STARS at six different elevation and polarization angles. The maximum RMS of orthogonal distance residuals from the best-fit paraboloid is 0.58mm, less than the design accuracy of lmm.
