Abstract

Remote sensing of the Earth is mainly carried out in the visible region of the spectrum, which corresponds to the current level of development of high-precision onboard instruments for Earth remote sensing. At the same time, methods and equipment for sensing in the radio- and infrared ranges of the electromagnetic spectrum are widely used and developed at a faster pace. The frequency of data acquisition ranges from once per month to once per minute, the spatial resolution ranges from kilometer to centimeter scales, and the electromagnetic spectrum covers wavebands ranging from visible light to microwave wavelengths. The efficiency of Earth remote sensing information delivery to consumers is considered under different variants of satellite-repeater network construction, taking into account the characteristics of existing and prospective high-speed radio lines of spacecrafts.
