In a SatCom system, a Mission Control Centre (MCC) is a set of functionalities which have two main objectives. Firstly, to ease the operation of the system (space and ground segment), then to benefit the maximum capacity of the payload and ground devices. As a consequence, the mission centre has to be considered as an efficient mean to increase the return of the investment made by the satellite operator.
Moreover, all the operators want to have integrated Mission Control Centre for global consistency, by proposing a merged planning, configuration and monitoring system
The main function addressed by a Mission Control Centre are :
Planning : to check feasibility of a deployment, and optimize on board and ground resources consumption, in order to enhance the system capacity.
Configuration : to deploy easily payload and station accordingly to what have been planned.
Monitoring : to check if the operation are in line with the plan and also to detect potential threat on ongoing transmission activities.
Thales Alenia Space has a long history in development and supply of Mission Control Centers for commercial and institutional Satcom missions
During the last decade, SatCom market is facing the introduction of new features, associated to the increasing needs of capacity, reliability and flexibility. Consequently the in-orbit validation, operation, planning and resource optimization of such systems becomes more and more complex, hence requiring to develop new operating concepts and tools.
These new features are mainly :
IP services with variable data-rate,
Ka Band bringing bandwidth improvement but also important fading.
Complex wave-form with adaptive coding and modulation.
Flexible payload increasing deployment possibilities with multi-beams, shared TWTA, Digital Transparent Processor (DTP)…
And for governmental systems, the struggle against Jamming threats either at monitoring and planning level or through the use of specialized anti-jamming devices.
The aim of this presentation is to give an overview on the new functions that had to be added to Mission Control Centre during last ten years in order to take up the challenge induced by these new technologies. We will see how new ground function have escorted these major change, and maybe more, how they had made some of these changes possible. Because, some of them wouldn’t have been a reality without the development of a dedicated ground software helping a non expert operator to plenty use them.

Designing Smarter Networks: Modeling Communications in the Era of Service Awareness, Social Networks and the Smart Grid
Combined advances in high speed networking, mobile devices, application sharing, web services, virtual world technologies and large scale event processing are converging to create a new world of pervasive, smarter networks, and ubiquitous “presence” of users, which offers tremendous potential for social interaction and co-creation. The communication networking and computing requirements of this converged human-centric environment are also increasing at an accelerated pace. In this new environment, it is imperative that the crucial networking and computing resources align closely with the needs and patterns dictated by the applications, social networks, and by the human users. The success of such socio-technical smarter systems will hinge on the way networks interact with human presence and location, in all of its physical and virtual aspects.
A robust, scalable, and dynamic communication infrastructure is necessary to connect service consumers and providers within such rich, interactive environments. It is also becoming increasingly relevant to the delivery of smarter health systems, and of the “Energy Internet” or “Smart Grid”, in conjunction with progress in energy storage, renewable generation, and smart metering. Applications of the future will leverage distributed service-oriented deployment patterns where large numbers of network appliances coordinate with peers using network-wide (or “cloud-wide”) application-specific policies, in order to perform configuration changes based on prevailing network, computing and application conditions.
Modeling and adaptation of resources based on state, location, context-awareness and workload (current or predicted) is highly desirable in these high-performance computing and communication socio-technical service systems. In this seminar, we provide an overview of our effort, in collaboration with our College of Management, with the new FREEDM center on renewable energy, with IBM and with Cisco, to develop models of emerging next generation network-based services, traffic characterization and predictive and dynamic resource allocation. We present an overview of approaches that we are using for service-aware utility-oriented modeling and resource allocation in aggregation network optimization, location-aware hybrid activities in wireless networks, smart grids and vehicle charging stations, smart health applications, and virtual collaboration environments such as virtual worlds.

Abstract. Maritime subject domain plays an important role in up to date world economy. World ocean covers over 70% of the Earth and forms many sources of energy and food. Needless to say that Maritime Observation Systems (MOS) serve as an important part of the world ocean investigation programs. Currently many different subject domains directly or indirectly incorporate MOS as a core of investigation and real business processes. Traditionally MOS bore somewhat military nature, however, in recent years the business and safety aspects became more important in the trends aimed at developing MOS for different purposes. And currently we observe many initiatives, groups and other real MOS related works around the Globe; like EU Marine Observation and Data Expert Group (MODEG) (http://ec.europa.eu/maritimeaffairs/eu-marine-observation-data-network-mission_en.html). The mission of MODEG is to provide the Commission with the scientific, technical and operational expertise to ensure that the European Marine Observation and Data Network (EMODNET) best meets the needs of its future users.
In Russia there exists a large program: National Unified System for Information on Situation in the Oceans that has been started a couple of years ago (NUSISO).
NUSISO is the information system which integrates technologies working in the Russian Federation for the observation, data acquisition and data processing regarding the situation in the oceans. This system is designed for information support of maritime activities at all levels: Federal, regional and departmental.
NUSISO encompasses over 1300 organizations from 45 departments of Russia, at that, using the databases of Data Center: All-Russian SCIENTIFIC RESEARCH INSTITUTE for Hydro meteorological information-world data center. Detailed information about the NUSISO program is presented on the NUSISO Web-portal(www.oceaninfo.ru).
The system of buoys “ARGO” can serve as an example of the international system. The ARGO project objective is to create and maintain a global network of 3000 buoys that should correspond to more than 100000 measurements performed by different sensors. The project objectives consist in: placing the specified number of buoys in the world ocean; establishing the Argo national centers; free access to data; transfer data to the global network within 24 hours after their receipt.
Detailed information about the ARGO project is available on web-sites given below:

The MOS analysis indicates that the following constituents are peculiar to the systems: the first and foremost to the point are monitoring and detection means, such as sonar, radar, optical and infrared detectors, magnetic, gravitational, and several others. The second – data centers and decision-making support systems at various levels of the hierarchy, depending on the MOS scale. The third – networks for data transmission and data exchange that implement (at the physical level) the MOS state of distribution and heterogeneity. All constituents are interconnected and mutually stipulated. Currently the number of data transmission networks is enormous, and consideration of the networks totality is hardly possible or practical. In the above regard the presented approach proposes to consider the standard MOS and the Hybrid Networks (HybNet) by example of MOS.
The paper proposes two basic MOS: ECDIS and AIS for further consideration. ECDIS is one of the first marine information systems, which has found wide commercial application. Here the requirements to data networks are minimal: transfer of maps’ corrections, weather, and information about the navigating-hydrographical conditions. AIS appeared due to the advent of GPS with capabilities of continuous monitoring of any surface ship. AIS is a supplementary system in the greater global MOS. VTMS is more complex and distributed heterogeneous system by right. VTMS meets in full the challenge of HybNet implementation. ECDIS and AIS VTMS analysis allows to develop a general approach to DMOS including: architecture, hierarchical levels, goals; networks: cell networks, wireless networks, satellite networks, optic networks etc. Based on the first hand experience in DMOS research and production the paper proposes to consider two more DMOS types developed by SPIIRAS: Sonar Monitoring System (SMOS) and Maritime Surveillance and Recognition System (MSRS).

Since 2000, she has been active in fostering the development of Ultra Wide Band (UWB) radio communications in Europe, and participated in several pioneering EU projects on UWB communications (within the 5th framework, whyless.com, first funded research project world-wide addressing UWB communications for civil applications, and project UCAN aimed at the design and implementation of UWB ad-hoc networks – within the 6th EU Framework, IP projects PULSERS and PULSERS II which integrated UWB research and development in Europe, IP project LIAISON on to location-based services). During this last decade Dr. Di Benedetto research main focus was on medium access control and management in wireless networks, as well as energy-efficient routing, and location-based optimization of medium access control and routing functions. In particular, participation in the European Network of Excellence HYCON (Hybrid Control: Taming Heterogeneity and Complexity of Networked Embedded Systems) offered the framework for an inter-disciplinary effort with colleagues from "Control Theory" that led to the formulation of hybrid models for complex wireless communication systems operating under coexisting conditions, and increased theoretical research activity in the field of cognitive and coexisting networks. Based in particular on this last rewarding and productive collaboration, Professor Di Benedetto recently promoted and coordinated a proposal for a COST Action on cognitive radio and networks. The proposal, that gathered over 30 partners of 15 countries in Europe, as well as the US, Canada, China, and Australia, ranked first in the COST Information and Communications Technology Domain and was approved in May 2009. The resulting COST Action IC0902 "Cognitive Radio and Networking for Cooperative Coexistence of Heterogeneous Wireless Networks" kicked-off in December 2009. In October 2009, Dr. Di Benedetto received the Excellence in Research award "Sapienza Ricerca", under the auspices of President of Italy, Giorgio Napolitano.

After a brief description of the current and shortly planned systems, as well as an introduction on the evolution key user requirements, this tutorial describes and analyses the key system design issues of current and future HTS broadband satellites. In particular, the main design factors impacting the system throughput and availability are reviewed, both at system, payload and ground segment levels. The key air interface requirements and evolutions are also addressed together with the relevant regulatory constraints, for both the forward and return links, and in the user and feeder links. Some key technological limitations and considerations of the ground and payload sub-systems are also discussed. A case study is finally presented with considerations.

Multi-functional Si/SiGe BiCMOS ICs in complex and reconfigurable mm-wave systems
Over the past 20 years, bipolar and BiCMOS technologies using Si/SiGe heterostructure bipolar transistors have become powerful competitors to established GaAs technologies for microwave and millimeter-wave applications. While the cost advantages of Si-based technologies are frequently touted, they materialize only in large quantities rarely found outside of the consumer market.
The more interesting advantage of Si/SiGe BiCMOS lies in the ability to realize highly complex multi-functional ICs which combine different RF building blocks on one chip together with digital and analog control electronics. The ability to put e.g. a digital bus transceiver with registers and D/A and A/D converters into single-chip transmit/receive modules of electronically steerable antenna arrays can lead to significant reductions in the complexity of the antenna interconnect system.
The increased complexity potential can also be used to realize integrated circuits with a high degree of flexibility, adapting to different use scenarios. They could thus be manufactured in larger quantities, and would lower cost due to lower chip cost (finally fulfilling the initial promise of Si-based mm-wave technology) and shorter time to market.
The presentation will discuss these technological potentials in detail, using two different Si/SiGe technologies – a very mature, truly low-cost npn-only SiGe HBT technology, and an advanced Si/SiGe BiCMOS technology which includes the monolithic integration of RFMEMS switches as an interesting option. It will show sample ICs in the 20-90 GHz range realized with these technologies, and discuss currently developments in the EU FP7 project FLEXWIN, which explores both mm-wave phased array antennas using an “intelligent pixel” concept, and ICs with a high degree of application flexibility.
