In many organisations and agencies, the teams developing the ground segment system software (software for mission data systems, flight dynamics, ground station systems, …) are distinct from the teams provisioning and maintaining the physical or virtual IT infrasucture, including the baseline operating system and packages/dependencies, on which the software runs. As a result, information such as which physical or virtual resources are supporting which mission on which infrastructure baseline version and with which version of infrastructure or mission-specific software is loosely coupled and not easily queried. Moreover, as the ground segment moves to a service-oriented and multi-mission architecture, multiple missions may rely on the same physical or virtual IT resources. The main idea of this activity is to provide a digital link between ground segment systems and the hardware (and potentially the systems used for monitoring, maintenance and provisioning of the infrastructure)on which the software is deployed. This shall include the definition of a physical deployment model for the system as a dedicated viewpoint on the overall system model for the ground segment. An example methodology which maps Such a digital link is expected to offer several benefits:- provision of a holistic view of the system with traceability across functional and logical architecture through to physical architecture, offering a single source of truth for the overall system design, configuration and deployment- enables improved resource utilisation forecasting and clarity on deployment plan and deployment status- the ability to have a machine-readable and query-able, bi-directional link between IT systems and ground segment software deployment. This is very useful in order to know which IT systems and infrastructure is used by each ground segment software system at any particular time- enables impact analyses of unavailability of systems e.g. of planned or unexpected downtime or of security incident occurrence on IT infrastructure verses the resulting mission/functional impact).Regarding the selection of the MBSE tools and the usage of existing system models to be integrated and extended, the contractor shall take into account and/or consider various related systems and tools such as:- The Ground Segment Engineering Framework (GSEF) development. This tool is currently under development and productization however a mature prototype is available. This tool is currently used for project-related MBSE work, including shadow-engineering for the Euclid mission ground segment and in support of multi-mission infrastructure (EGOS-MG) system engineering. The tool is currently undergoing major development and in the case that re-use of this solution is adopted, the contractor shall interact with the existing development teams. The system can be provided as an IMA.- The Ground Segment Reference Baselines (GSRB) which provide a preliminary reference baseline for a mission operations ground segment. These have since been extended for EGOS-MG modelling work.- DASP which is a web based tool used at ESOC to model missions and software deliveries. – The ESA Architectural Framework. This framework, implemented in the MagicDraw tool is intended to be utilised in the EGOS-MG project, potentially also for physical and deployment architecture modelling.- ECDB which is a tool used at ESOC to model ground stations and their systems, including software and hardware and map functional versus physical architecture. – ITSM, which is the system used internally at ESOC for managing mission related hardware. Each mission can see which systems belong to them (hardware /virtual) and what operating baseline each system has, along with other information.The contractor is free to propose also other solutions.
