| Abstract: | This paper, the third in a series on the design, payloads, and operation of Soviet earth resource observation satellites [see MSRS, 1984, No. 4 and 1985, No. 1], describes the collection of supplemental sub-satellite information. More specifically, it outlines how the Soviets use satellite-synchronized aerial, ground, and water-borne sensors to gather auxiliary information used in the improvement of space imagery (data verification and correction, instrument calibration, etc.). A later section demonstrates procedures for selection and preparation of field test sites (for ground truth), and design of sub-satellite information measurement complexes.
