On-board Hardware (Storage and Communication) Requirements

The corresponding task covers the collection of the different communication-related processing requirements and different on-board storage requirements, as derived from the identified subset of applications, payload processing requirements as well as from on-board management software requirements (derived from, respectively, T1.1, T1.3, T1.2). It also foresees the initial definition of benchmarking activities to be carried out, and derives the relevant S4Pro storage requirements. This task will: - List the relevant CCSDS documentation regarding communication from the spacecraft to other spacecraft or to the ground (e.g. Space Internetworking Services, Space Link Services) and translate these into technical specifications for the telecommunication subsystem (QAS, iTUBS) and the data communication system (DSI). - Provide the different application-related on-board storage requirements, starting from the requirements from T1.1, T1.3 and T1.2 (DSI). - Collect, compile, harmonise and formalize requirements (ARTTIC). - Analyze them to identify, for each specific requirement, data throughput/transfer speed and storage size. - Evaluate the feasibility of miniaturization strategies of mass-memory module in order to integrate it with nano-satellite platforms (iTUBS). - Validate the approach for what concerns the interface between the SDR and the on-board storage system (QAS). - Define a preliminary benchmarking plan in order to test the on-board storage capabilities (DSI). - Evaluate the minimum required level of implementation needed to be considered “CCSDS compliant product” for what specifically concerns the telecommunication subsystem (QAS, iTUBS) and the data communication system (DSI). - Coordinate requirements capture and feedback from Advisory board and the integration of their recommendations in D1.4 (ARTTIC).
