Abstract
An experimental setup and experiments on measurements and calculation of light pressure on constructional materials at different light angles are presented. This calculation is necessary to determine the lighting properties of a material and the total solar pressure moment. Industrial metal-knitted textile was used as a constructional material. Metal-knitted textile is a material for large-diameter spacecraft antennas. More than 4000 experimental measurements of the transmittance and reflection coefficients of the metal-knitted textile were carried out for the calculation.
