摘要
One of the available capacities of satellite application is applying in Earth Observation (EO) video capture satellites. On the one hand, the governing equations of satellite motion in orbit indicate the fact that a satellite moves in a very predictable manner and stays on schedule. On the other hand, the superiority of Intra and Inter codings, drive video compressors to reduce the spatial redundancy and data rate. This advantage stems from the flexible coding structure and high density of angular prediction modes, in all video compression versions. How to combine these facts to achieve better performance in industrial satellite applications is our aim in this article. In this study, a novel architectural approach for EO video capture satellites that have taken the new demands of the next commercial market has been proposed. Here after looking at video coding parameters, technical EO satellite essentialities, and proving the proposed hypothesis by simulation and evidence, a preliminary configuration has been described. The Attitude and orbit control systems (AOCS) are responsible for keeping the satellite position in the required condition contributing to Onboard Data Handling (OBDH). The exact parameters of direction are key factors that can be used besides video prediction vector data to reduce calculation load in video compression algorithms that particularly explained.
