The European Ground System -Common Core (EGS-CC) will soon provide a common infrastructure to support space systems monitoring and control in pre-and post-launch phases. For several years, Telespazio VEGA has relied on a ground control segment infrastructure based on ESA SCOS-2000 and Telespazio VEGA components. This core control segment is now being extended and migrated to EGS-CC to align on the state-of-theart technology of the new monitoring and control infrastructure while ensuring the completeness of the control segment through the addition of operationally proven components. This paper presents the characteristics and benefits of the Telespazio VEGA core control segment and introduce the various components, focusing on their integration with EGS-CC.

ABSTRACTIn this paper we discuss a fast reconstruction of an archaeological site consisting of many different and connected parts. In particular, we discuss the geometric reconstruction of the Domus Flavia and the Domus Augustana, both built by Emperor Domitian on the Palatine hill in Rome, including the adjacent Hippodromus. The Domus Flavia was the official part of the palace, while the Domus Augustana was the emperor's luxurious private residence. They are the most impressive ruins remaining today on the Palatine. The aim of this paper is to introduce the reader to the power of generative semantics, and to show how fast and easy is the generation of complex VR models if using a generative language. For this purpose, we capitalize on a novel parallel framework for highperformance solid and geometric modeling, that (a) compiles the generating expressions of the model into a dataflow network of concurrent threads, and (b) splits the model into fragments to be distributed to computational nodes and generated independently. We trust that both the language and its kernel are suitable for Cell-BE (Broadband Engine) implementation, that someone believes the reference architecture for advanced modeling, imaging and simulation of next years. be used as a proof-of-concept for such top-down development, we use the geometric language PLaSM and shortly introduce its syntax, semantics and use modes. PLaSM, (the Programming LAnguage for Solid Modeling) is a design language, strongly influenced by FL (programming at Function Level), a novel approach to functional programming developed by the Functional Programming Group leaded by John Backus and John Williams at the IBM Research Division in Almaden in the first nineties [2], [3]. PLaSM is a geometric extension of FL, allowing for a powerful algebraic calculus with dimensionindependent geometric objects that include polyhedral complexes and parametric polynomial and rational manifolds (curves, surfaces, curved solids, and higher-dimensional objects). In this environment for geometric computations, a complex shape is generated as an assembly of component shapes, highly dependent from each other, where (a) each part may result from computations with other parts, (b) a generating function is associated to each, (c) geometric expressions may appear as actual parameters of function calls. This functional approach implements an algebraic calculus with geometric shapes, where a direct mapping is possible between values of the calculus and expressions of the language. This approach, based on dimension-independent representations with guaranteed geometric validity, leads to a versatile approach to Virtual Reality, supporting classes of objects with varying topology and shape, and also retains the good properties of functional programming. In particular, it allows writing program code which is clear, highly concise and self-d...

For the last 15 years, Mission Control Systems (MCS), developed for the operational monitoring and control of spacecraft and missions and operated by Flight Control Teams (FCT) at the European Space Operation Centre (ESOC), have been built on top of the SCOS-2000 infrastructure. This infrastructure is going to be phased out, in favor of an infrastructure based on the European Ground Systems -Common Core (EGS-CC) as the core implementation for future Monitoring and Control Systems, both for the pre-as well as for the post-launch phases. EGS-CC introduces substantial differences in all phases of the software development lifecycle in comparison to the current MCS development process based on customizations of SCOS-2000. After more than 20 years of SCOS-2000 based MCS development, the software development approach introduced by EGS-CC can be seen as a major milestone and its adoption will ultimately impact the development lifecycle of MCS applications. This paper addresses all the changes that EGS-CC introduces, which are relevant for MCS software developers and testers, and their impact on the software development lifecycle (specification, design, implementation, integration, validation, deployment) with reference to ESOC's current practices and systems are highlighted. The results of the analysis with respect to the MCS development are presented in the context of ESA's GAIA mission.
