Optimal task scheduling for multiple satellites under 3d imaging constraints

Abstract

Since 1990s, stereo image acquirement from satellites has become increasingly important. Stereo images can be used to extract digital elevation data to create a digital elevation model (DEM) or used for Earth mapping, Earth monitoring and so on. To generate a stereo image, a target must be viewed from at least twice from slightly different angles. In this paper, a conventional optimal multi satellite scheduling problem is modified to accommodate stereo imaging constraints. A description and formulation of the problem is provided with simulation results.
