Abstract. Technologies of small object observation planning and survey with the use of space-based opticalelectronic remote sensing systems are studied. A brief analysis of methods used to reduce the volume of recorded data is presented. The possibility of contraction of spatial redundancy in a one-dimensional array of data recorded on board of the spacecraft is investigated. Models of survey objects for nonstationary observation conditions are developed, a method for reduction of spatial redundancy is proposed.

Keywords: spatial redundancy, target data, spacecraft, remote sensing, object of imagery, photogrammetric refraction, stochastic parameters, rational polynomials
