ADHA SOFTWARE ARCHITECTURE - EXPRO+

Objective: To develop a complete Software product portfolio of building blocks facilitating the integration of ADHA platforms in Mid-size LEO satellite platforms.Description: The Advanced Data Handling Architecture (ADHA) has been developed as a set of hardware components with standardized communication interfaces. Previous work has focused on the hardware aspects, but the current situation highlights the need for a robust software stack to support ADHA in space missions, in particular mid-sized LEO satellites. The main concern is to ensure that enough software components are ready for use in flight and developed using modern, modular techniques to enhance compatibility and performance. This activity aims to provide a modular software stack that can be utilized across different ADHA-based computers, including On-Board Computers (OBCs) and Instrument Control Units (ICUs) from various vendors. By leveraging different European processors, FPGA, and other COTS processors commonly used in commercial satellites, the software stack is aimed at offering flexibility and interoperability. The added value includes improved mission reliability, reduced development time, and cost savings through standardized software components. The configuration and deployment of the software will be integrated into a model-based software development and code generation tools such as TASTE using Space Creator, facilitating streamlined development and deployment processes. Future activities may involve further refinement of the software stack, extending compatibility to additional processors, and continuous improvement based on user feedback and mission requirements. This activity encompasses the following tasks: -Assessing the feasibility of a modular software stack for different ADHA-based computers. - Developing the software stack to support multiple European processors. - Integrating the software stack into a software MBSE toolset (e.g. TASTE). - Testing and validatingthe software stack across different hardware configurations. - Documenting the development process and results. Software shall be delivered under an ESA Software Community Licence, allowing access and updates by individuals or entities within ESA Member States.
