    The research contributes to work in Rapid Deployment of a National Public Security and Emergency Communications Network using Communication Satellite Broadband. Although studies in Public Security Communication networks have examined the use of communications satellite as an integral part of the Communication Infrastructure, there has not been an in-depth design analysis of an optimized regional broadband-based communication satellite in relation to the envisaged service coverage area, with little or no terrestrial last-mile telecommunications infrastructure for delivery of satellite solutions, applications and services. As such, the research provides a case study of a Nigerian Public Safety Security Communications Pilot project deployed in regions of the African continent with inadequate terrestrial last mile infrastructure and thus requiring a robust regional Communications Satellite complemented with variants of terrestrial wireless technologies to bridge the digital hiatus as a short and medium term measure apart from other strategic needs. The research not only addresses the pivotal role of a secured integrated communications Public safety network for security agencies and emergency service organizations with its potential to foster efficient information symmetry amongst their operations including during emergency and crisis management in a timely manner but demonstrates a working model of how analogue spectrum meant for Push-to-Talk (PTT) services can be re-farmed and digitalized as a “dedicated” broadband-based public communications system. The network’s sustainability can be secured by using excess capacity for the strategic commercial telecommunication needs of the state and its citizens. Utilization of scarce spectrum has been deployed for Nigeria’s Cashless policy pilot project for financial and digital inclusion. This effectively drives the universal access goals, without exclusivity, in a continent, which still remains the least wired in the world

    The role of science in physical natural hazard assessment : report to the UK Government by the Natural Hazard Working Group

    Get PDF
    Following the tragic Asian tsunami on 26 December 2004, the Prime Minister asked the Government’s Chief Scientific Adviser, Sir David King, to convene a group of experts (the Natural Hazard Working Group) to advise on the mechanisms that could and should be established for the detection and early warning of global physical natural hazards. 2. The Group was asked to examine physical hazards which have high global or regional impact and for which an appropriate early warning system could be put in place. It was also asked to consider the global natural hazard frameworks currently in place and under development and their effectiveness in using scientific evidence; to consider whether there is an existing appropriate international body to pull together the international science community to advise governments on the systems that need to be put in place, and to advise on research needed to fill current gaps in knowledge. The Group was asked to make recommendations on whether a new body was needed, or whether other arrangements would be more effective

    This aim of paper is to presents the development of a multidisciplinary project carried out by the cooperation between Politecnico di Torino and ITHACA (Information Technology for Humanitarian Assistance, Cooperation and Action). The goal of the project was the training in geospatial data acquiring and processing for students attending Architecture and Engineering Courses, in order to start up a team of "volunteer mappers". Indeed, the project is aimed to document the environmental and built heritage subject to disaster; the purpose is to improve the capabilities of the actors involved in the activities connected in geospatial data collection, integration and sharing. The proposed area for testing the training activities is the Cinque Terre National Park, registered in the World Heritage List since 1997. The area was affected by flood on the 25th of October 2011. According to other international experiences, the group is expected to be active after emergencies in order to upgrade maps, using data acquired by typical geomatic methods and techniques such as terrestrial and aerial Lidar, close-range and aerial photogrammetry, topographic and GNSS instruments etc.; or by non conventional systems and instruments such us UAV, mobile mapping etc. The ultimate goal is to implement a WebGIS platform to share all the data collected with local authorities and the Civil Protectio

    NewSpace and the european space economy

    A guide for engineers to better understand space economy. A guide for policy-makers to better understand the space sector. The statement above is probably the best way to sum up the main goal of this work: to connect space engineering and economy in a theoretical approach. The proposal for the thesis is to study the economy of space in Europe and the main challenges for the crucial future decades. This work is intended to give insight into economic strategies in order to enhance the growth of the space sector whilst also detailing the state of space technology in Europe today. This thesis should be useful as a guide for those looking to comprehend the state of space technology in Europe, those interested in creating new companies and those who want to invest in space technology. The broader goal is to focus on solving the fundamental Five Ws with respect to space technology and its socio-economic consequences in Europe. All fundamental questions must be assessed avoiding prior subjective assumptions and/or desired outcomes. Space is experiencing a major shift from concentrated government-lead projects to an ever-increasing volume of commercial activities. This thesis aims to break down the fundamental aspects that are driving the current transformation of space1 while also taking a deep dive into the European space sector, future space economy trends and Europe’s role in the global space sector. In addition, the future of space clusters, space agencies and private-public interactions will be studied. The statement and aim are broad indicators of the contents of the thesis. Before defining specific objectives, some of the topics need defining in a more precise way. Let us make a list of relevant topics to be assessed in the thesis: The emerging NewSpace and Space 4.0 agenda proposed and adopted by ESA require space technologies to be developed coordinating public and private sectors. The rapid increase of private market ecosystems in space in the US and the emerging Indian and Chinese Space markets urge Europe to develop strategies to compete by fostering new private endeavours and stimulating the creation of new markets. Space in Europe may focus on optimizing regional technology clusters paying more attention on regions which could play a larger role in ESA’s industrial policy in the future. Considerations on the creation of new high-tech jobs for social and political concerns would create new opportunities to least developed countries. New financing models or investment communities to effectively catalyse dynamic risk capital investments and additional private investments in the sector. This can be done by studying economic profitability, its relation to specific space technologies and dependency on short/long term growths. A new approach to further linking universities, research institutions, private companies and ESA could be an interesting tool to fully develop student skills and interactions in the real world. An overview of clusters and ecosystems can be key to understand how policy makers can stimulate the growth of the space sector

    The regime complex of global space governance : the international space politics of the 21st century

    Get PDF
    Post-Cold War trends in national space-capability building and the liberalization of the global space economy have expanded the concerns of states in international astropolitics from security as such to other issue areas, including safety, economic growth and social development, and sustainability. Since the beginning of the 21st Century, the constellation of international space regimes has continued to expand, while the global governing architecture has fragmented. Within a ‘regime complex’ analytical framework, this work presents two interpretive narratives of the strategic, functional and organizational aspects that explain the design and evolution of ‘the regime complex of global space security governance’ and ‘the GNSSs regime complex’. The case studies chart the dynamics of international space politics and analyze the growing structural fragmentation of the complex global scheme of space governance. An additional enabling factor such as innovation was identified as vital to reinforce the growth of regime complex in global space governance
