Current barriers and factors of success in the diffusion of satellite services in Europe

Satellite services benefit civil society by helping tackle challenges such as climate change, the digital divide, etc. They have the potential to deliver concrete benefits to European society through innovative services supporting economic, societal and environmental policies. Such benefits can trigger increased public support for space in Europe. However, this potential has yet to be achieved. This paper argues that technological bias, the diversity of interests and initiatives among stakeholders and their individual actions do not always serve their collective objective to ensure wide diffusion of satellite services. It draws on theories of diffusion of innovation and on its authors' participatory work with the space and the user communities and at their interface in an effort to help diffuse satellite services within civil society. One of the major causes of insufficient service diffusion is the weakness of the interface between the space and user communities; some of factors that currently contribute to this state of affairs are the space community's over-reliance on publicly financed, technical demonstration projects as solutions to service diffusion; insufficient coordination by public authorities of innovation policies and programmes with other public policies and objectives; and an insufficient integration of satellite services within users' culture, traditional tools and services. The discussion allows for conclusions to be drawn on how the system of stakeholders could function better in order for satellite services to be successfully diffused in Europe.     

Communications satellite business ventures : Measuring the impact of technology programmes and related policies

Both commercial organizations and government agencies invest in spacecraft technology programmes aimed at increasing the performance of communications satellites. Government agencies also make policy decisions which may affect communications satellite business ventures. This article describes an economic evaluation and planning tool which has been developed to assess the impact of various policies on typical fixed satellite service business ventures. The methodology is based upon a stochastic financial simulation model (DOMSAT II) which allows for consideration of reliability and various market, performance and cost uncertainties. Results of the assessment of NASA on-orbit and space power technology programmes are presented, as are results of insurance v self insurance decisions and the choice of transportation system.     

S@tMax—A space-based system enabling mobile IP applications in vehicles

As personal mobility increases, people spend more time in their vehicles. Furthermore, a large segment of today's workforce is part of a growing mobile service industry. This mobile society creates opportunities to increase productivity which do not yet exist. Today's commuting time could be better utilized and mobile business transactions could be more efficiently conducted, by integrating mobile IP wireless services in vehicles. By means of a direct to mobile user Internet access, and total IP services, integrated into automobiles, S@tMax services can empower the mobile business movement therefore improving productivity. This paper presents a commercial system architecture that will deliver an optimized solution for direct to mobile user Internet access, through an integration of a ground based network infrastructure, use of existing communications satellites and the development of a proprietary satellite system. As a result of a detailed systems engineering process, the architectures of the space, ground and infrastructures segments will be presented. Furthermore, the benefits of on-orbit servicing were examined in the S@tMax context. The approach proposed is considered as an important step towards enforcing main roadway IP coverage in the US, for near-continuous communications and services.     

Competitiveness of commercial space transportation services

Competition between the providers of space transportation has become intense with the distinct possibility of governments providing both direct and indirect subsidies in order to influence transportation user choices. This bodes well for users of transportation services but has serious ramifications with regard to the future makeup of the international space transportation industry. This paper addresses the following key issues: selecting a launch service given a decision to establish a business to provide satellite communication services; establishing the price that should be bid by a launch provider in order to have a specified chance of being awarded the launch contract; and assessing the possibility that a launch provider is utilizing unfair or predatory pricing in order to increase the likelihood of winning launch contracts and thereby increasing market share. A method is developed and results presented based upon establishing ‘value in use’ pricing that explicitly takes into account the multiple attributes of alternative launch services. This leads to an assessment of ‘predatory’ pricing in terms of the value in use pricing.

Status and prospects of China''s space programme

This article presents the current status and characteristics of China's space programme before describing the country's future goals and the specific types of research and satellite production that will be undertaken to realize them. China's programme, although small, has achieved much in terms of economic and social benefits for its people (eg through land-surveying, communications, education, water conservation and earthquake prediction). This is a result of the emphasis place on applied-satellites, coordination of production, development and research and intensive ground testing. This emphasis will remain, along with the effort to ensure that new satellites are long-lived and stable in operation. However, a change from the previous policy of independence is signalled by a growing interest in international cooperation, including that with other developing countries like Brazil.     

Fast-track development of space technology in China

China's space industry faces challenges from the rapid growth in domestic demand for satellite services, international competition from the other members of the space club and infiltration of its domestic markets by foreign space companies. To counter this the country is making space a priority in current plans to improve national economic and social development, paying particular attention to applications satellites. Policies aimed at accelerating development include increasing state support for space, improving management - especially of invested funds - creating a better infrastructure and aiming for serial production of satellite components. It is acknowledged that much can be learnt from other countries and China is keen to pursue cooperative endeavours, but it intends also to retain its independence.     

Talking space: The European Commission's changing frames in defining Galileo

This paper traces the way in which the European Commission has framed and reframed the issue of EU satellite navigation over 20 years. It investigates how the EU's agenda-setter has ‘talked about’ space policy, with a particular focus on Galileo, and how its own institutional discourse – as revealed in its communications throughout the agenda-setting stage of Galileo's ‘definition’ phase – evolved in the 1990s through the use of ‘frame sets’. In so doing, it illustrates the ways in which, over time, the EU's executive has ‘projected’ the issue of independent satellite navigation capabilities as being politically and economically desirable for Europe, and has sought to persuade decision makers of its cross-policy relevance and potential economic, social and security benefits. The article deconstructs official documents and engages in a close-up analysis of policy formulation, to identify nascent, evolving and mature frames in the definition of Galileo.     

Evaluating the economic impact of design alternatives on domestic communication satellite ventures

What are the economic consequences of establishing a domestic communication satellite venture? Has the best design alternative been selected? Should investments be made to develop new technology? How much should be invested? These are but some of the questions facing those concerned with providing domestic communication satellite services. Because of the demand, performance and cost uncertainties and the unpredictability of the need for and timing of large capital expenditures (due to less than perfect reliability of transportation systems and satellites) providing answers to these and other related questions is a complex process.This paper describes a methodology for providing answers to the above questions. The methodology, by explicitly considering demand, performance and cost uncertainties and satellite and transportation system reliability, develops probabilistic pro forma financial analyses of domestic communication satellite system ventures. In so doing, the risk dimension is quantified and alternative courses of action can be evaluated and compared taking into account expected values, risk and risk aversion preferences. It is also important to quantify and consider the risk dimension since many R &; D projects are specifically aimed at risk reduction.     

Economic methods of improving efficient use of the orbit/spectrum resource by satellite systems

Satellite systems continue to play an important role in the booming market for communication and broadcasting services, driving up demand for use of the orbit/spectrum resource. Studies are required to address the problem of orbit capacity and find ways of making more efficient use of it, to avoid a situation in which there is not enough orbit/spectrum resource to cater for the development of future satellite networks. It is argued that, as far as satellite networks are concerned, the current international regulatory regime governing the use of the spectrum has significant shortcomings, which have a cost, in terms of resources and time, and make investment in satellite projects less attractive. An approach is proposed for improving efficiency of the use of the orbit/spectrum through the introduction of economic methods, to supplement the existing technical and regulatory regime. A spectrum pricing method is proposed for satellite communication systems.

INTELSAT and the challenge of competitive systems

If one accepts the overriding economic and social importance of telecommunications, then the importance of major shifts in international satellite policy becomes clear. In particular, proposals within the USA to redefine its relationship to the INTELSAT global satellite system take on broader significance than might be initially assumed. To understand why this is so, one must first focus on the role of INTELSAT and how it has changed the world of global telecommunications, at the national, regional and international levels.

The challenges facing Galileo

Study of the nascent European satellite navigation system, Galileo, is well underway and a decision by the EU Council of Ministers on whether to proceed with the test satellites is expected by late 2000. Although some believe that current systems, most notably the US GPS, make it unnecessary, the history of satellite navigation so far provides some justification for a European system. Nevertheless, Galileo faces a number of challenges if it is to succeed. These include not only the technical specifications for a new generation of navigation satellites and the ground structure, but also a coherent business plan for funding the launch, operation and maintenance of the system. Lastly, one has to consider the compatibility and interoperability of Galileo with the existing GPS and Glonass satellite systems, as well as the likely competition from GSM and (third generation) UMTS mobile services.

The role of Venesat-1 satellite in promoting development in Venezuela and Latin America

Built in cooperation with China, at the end of 2008 the Bolivarian Republic of Venezuela launched its first telecommunications satellite which operates in C, Ku and Ka bands. Using published and unpublished information, this report describes the potential role of the Venesat-1 satellite in promoting development in Venezuela and Latin America. The core of Venezuelan space policy has deep social roots and includes several applications in order to provide telecommunications services to people in all areas of the country. Potential roles of the Venezuelan Satellite in local and regional development include: strengthening environmental tele-education and telemedicine programs; improving disaster management through short-term development of broad networks to monitor environmental and meteorological features; coordination of emergency responses and humanitarian assistance using data and satellite communications; poverty reduction; and biodiversity conservation – communication networks could also be used to relay information about detected fires within protected areas faster, and to improve surveillance activities within them with in order to reduce illegal hunting, logging, habitat loss and fragmentation. Because the area covered by the satellite goes beyond Venezuela’s borders, its applications could have enormous relevance for human development at the regional level; they could be fundamental tools for bringing sustainable development into Latin America, by building capacity and increasing awareness among decision makers and lay people.
