N2 - This paper presents the system architectural aspects of the Land and Ocean Global Observation from Space (LOGOS) mission. The LOGOS mission is to develop an operational Earth observation system for vegetation monitoring and ocean color applications. The system is required to provide consistent means of predicting the near and long term trends in global commodities such as food supplies; terrestrial and aquatic. Products derived from the mission will be exploited to support economic predictions of the global marketplace for access by user community in the simplest means according to user needs. The system domain will encompass two areas; vegetation monitoring and ocean colour. Regarding vegetation, one of the constraints is to provide continuity to the VEGETATION program by CNES (Centre National D'Etudes Spatiales), with increased performances in terms of revisit time and spatial resolution. The main objectives are monitoring the vegetation state to support the assessment and forecast of commodity products. Regarding ocean colour, there is a mission opportunity to monitor the concentration of phytoplankton in ocean water that, in conjunction with other parameters like sea temperature and positioning, can be used to assess and forecast the presence and location offish. This product may impose certain constrains in terms of revisit time. The first part of the paper identifies the key mission technical and programmatic drivers such as worldwide coverage, timeliness, products characteristics/quality and data continuity. Baseline system concept is then presented along with architectural trade offs. The preliminary system architecture follows this; functional and physical architectures encompassing both space and ground segment. Finally, concept of operations is presented followed by a discussion of system performance. The overall system design concludes the paper. This work has been performed in the context of the Central Case Project (CCP) of the 10th European post-graduate Masters program on space systems and business engineering, Space Tech (by TU Delft TopTech), under sponsorship of CNES. Contributions by the entire ST10 team are gratefully acknowledged.
