                         reliability and reduced development time drives the new challenges 
                         of space missions. Consequently, ground segment has to be aligned 
                         with the requirements defined by space segment to improvement the 
                         synergy between these segments. Traditionally, a ground segment is 
                         a ready-to-run system; notwithstanding, during the mission 
                         development, new requirements can be requested. In this scenario, 
                         many questions are raised in order to meet cost and operability 
                         requirements and contribute to systemic solutions, such as 
                         document-centric designs, adoption of integration and testing 
                         procedures aimed at the ground segment, cultural inertia, 
                         information sharing policies and new project methods. Ground 
                         segment design has to demonstrate the concepts innovations that 
                         are required for the increase in data types and volume, and their 
                         processes, communications protocols, as well as modern development 
                         methods. These concepts are found in the recommendations of the 
                         Consultative Committee for Space Data Systems (CCSDS), for: a) the 
                         standardization of the managerial interfaces of the Tracking, 
                         Telemetry, and Command (TT\&C) services, b) the Space Link 
                         Extension (SLE) Protocol services for the cross support and 
                         interoperability. In addition, these concepts collaborate with the 
                         goals of the Interagency Operations Advisory Group (IOAG), for 
                         achieving full interoperability among member space agencies. The 
                         guidelines of the European Cooperation for Space Standardization 
                         (ECSS) and National Aeronautics and Space Administration (NASA) on 
                         systems engineering area also cover such concepts for system 
                         development, not limited to these major entities. In this paper, 
                         we provide an overview from space segment requirements to the 
                         ground segment requirements on the point of view of Model-Based 
                         System Engineering method and the SysML modeling language to 
                         formally describe and specify a space system, notably for the 
                         Satellite Control Center and the Telemetry, Tracking and Command 
                         (TT\&C) ground stations at the National Institute for Space 
                         Research (INPE). The aims of this work is to establish a process 
                         for optimization, management and implementation of the ground 
                         segment designs in a model-based approach, also considering an 
                         ontology. In such a way, we intend to improve and standardize the 
                         systems engineering practices and concurrent engineering 
                         procedures. The paper addresses the following topics: challenges 
                         for ground segment development, a space system overview, the INPEs 
                         ground segment evolution; concepts adopted as systems engineering, 
                         MBSE, ontology, language, and technologies; MBSE applications for 
                         space systems, and a process using MBSE.",
