This paper describes methods and results of the study of a complex for measuring the spectrozonal radiance factors in the UV, visible, and near-IR ranges. It has been checked in the laboratory and in full-scale experiments that the characteristics of the apparatus correspond to the technical requirements. The greatest detail for the recording and presentation of the spatial distribution of the radiance factors is 492×574 elements. The measurement error of the radiance factors in the range 0.1-10 is no more than 20%.
