1 Final Report 1 Introduction 1.1 Scope of the document This document provides the main findings of the study "Geo-Oculus - A Mission for Real-Time Monitoring through High Resolution Imaging from Geostationary Orbit". The study teaming is as follows: • Astrium GmbH Study Prime • Astrium SAS Instrumentation and LoS • Astrium Limited Mission Analysis • DLR Institute for Optical Systems Focal Plane Analysis The following consultants have contributed to the definition of the suitable applications and the collection of the product requirements: • ACRI-ST Traffic & Security at Sea, Earth Science Applications • Brockmann Consult Marine Applications • Infoterra GmbH Land Applications The first task of the study has been an open minded survey for applications for a mission that combines fast-response, high-revisit, near-real-time and high-resolution capabilities to introduce a new class of Earth observation missions. Figure 1.1-1 illustrates the uniqueness of Geo-Oculus to provide high resolution images in the scale of Sentinel 2 at the revisit time and the timeliness of MTG. Based on the survey for applications a set of mission objectives has been selected in consultation with ESA for sizing of the system during this study. Chapter 2 gives a short overview on the starting point for the survey and describes the approach for the selection of the mission objectives. The mission objectives are briefly described in 2.2. The second task of the study has been to derive and analyse the system requirements and to establish the preliminary candidate mission concepts. In chapter 3 the driving system requirements are summed up. The major system trade-offs "Field of View vs. resolution", " Magnetic Bearing Wheels vs. Electric Propulsion for manoeuvres", "Manoeuvre time vs. image post-integration effort" and "Image post integration and Inter-channel co-registration" are described in 3.2 Doc.
