The objective of this activity is to develop a Sentinel2 Simplified Level 2 Product Prototype processor (SL2P) software. During the in-orbit commissioning phase of Sentinel2, the SL2P software will be used in ESA/ESTEC in order to perform sensitivity analysisto estimate the achieved accuracy on these Level 2 products, to assess the Sentinel 2 end-to-end mission performance for the retrieval of a set of geophysical parameters, and to provide a selected set of products to the users community. The selected Level 2a products are: Aerosol Optical Depth (AOD), Water Vapour (WV), and Bottom-of-atmosphere reflectance. In this process, Cirrus cloud detection and correction shall also be implemented. The selected Level 2b products are: Generic Land cover classification, Leaf Area Index (LAI), Fraction of absorbed photo-synthetically active radiation (FAPAR), Leaf chlorophyll content (Cab), and Leaf water content(Cw). In this activity beside the software development task, the contractor shall define the ATBDs for the Level 2a whereas on the Level 2b the ATBDs will be provided as CFI from the agency (two methods for each Level 2b products). For the level 2a processing chain, the following two methods shall be implemented: the first one based on a Customer Furnished Item (CFI) provided by ESA and the second one based on a method to be defined by the Contractor. It is therefore expected that the Consortium will have relevant experience in atmospheric corrections, geophysical product generation and software development. The subject ITT is open to companies from ESAMember States , from the GMES Space Component , GSC Participating States, as well as from the participating countries to the Seventh Framework of the European Community - EC (EC FP7).

Update Reason:    Tender issueAdditive manufacturing (AM) is defined as the "process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies, such as traditional machining. The Additive Manufacturing (AM) technologies are maturing rapidly for metallic and polymer materials. Functional parts made by using AM are spreading in all sectors of industry.The materials that can be processed are polymers, metals, composites and some ceramics. The design, manufacturing and optimization of the shape of new parts using these materials/processes are reduced in time and customized to the specific use. The AM technologies allow creating shapes with a great degree of freedom directly from CAD files. The dimensions of the parts can range from few millimetres up to few meters. It can also provide significant schedule improvement as complex shapes can be manufactured without significantly impacting a standardized production flow. This freedom in design could be used also to release constraints in the logistics of telecommunication satellites. The packaging of sub-systems, the ground support equipment, the dummy masses, the interface brackets to test equipment and many elements of the satellite could be obtained more quickly or at lower cost or with improved performances by using these manufacturing technologies. The purpose of this activity is thus with a scope limited to telecommunicationsatellite platforms - (1) to analyze the applicability of AM technologies for the production of different systems and subsystems of telecommunications missions and (2) to assess the benefit on cost savings, potential assembly, integration time and mass savings at systemlevel. To this aim, the activity shall as minimum: (1) Define reference / use cases of systems and of sub-systems for which the proposed technique is to be evaluated as well as the corresponding criteria: production costs and schedule, mass, reliability, both space segment and ground support equipment (dummy masses, shall be addressed; (2) Review the corresponding manufacturing and testing process(es) and assess the performance for the existing process for the existing process and metrics; (3) Propose methods and identify processes with AM; (4) Evaluate the metrics for the references cases when using the AM; (5) Provide a complete cost benefitanalysis for the reference cases; (6) provide guidelines for the specification and design of the new parts; (7) Propose a detailed technology development roadmap for future telecommunication satellites, identifying return on investments; (8) Identify players from ESA member states and Canada that could play a role in implementing the proposed roadmaps.

Update Reason:    Tender issueExtensive and detailed cloud coverage and atmospheric conditions data, available from space and ground observations, can be used for estimating the performance of an optical link through the atmosphere in a variety of scenarios, e.g., link from GEO to ground, LEOto ground deep space to ground. Site-diversity is a link-impairment mitigation technique to increase the optical access availability(i.e., link availability) by increasing and optimally locating a number of ground stations. In order to dimension the network of optical ground stations to fulfil link requirements while keeping complexity and costs under control, accurate knowledge of cloud statistics and atmospheric conditions statistics over an adequate time span is necessary. This study shall include an accurate quantitative assessment of the optical access availability between space and ground and, based on this analysis, the system architecture (ground segment and space segment) shall be derived. The achievable performance (e.g., link availability vs number of optical ground stations) shall be estimated for different space-to-ground link scenarios.
