Convergence and technology acceleration in non-safety aeronautical mobile-satellite communications: Policy for the 21st century

Commercial activities from outer space have largely consisted of satellite communications. Whilst the maritime and land-mobile services can now be regarded as mature, the next growth area is anticipated in the provision of non-safety aeronautical mobile-satellite services, a service which is now poised to expand significantly in an era marked by competition and convergence of communications technologies. This article highlights and analyses pertinent institutional, legal and regulatory issues, describing what the law is, while making recommendations relating to what the current law should become if the rules were changed to accord with good policy.     

China's space communications goals

As a large, developing country with poor communications networks, China is in a good position to benefit from satellite communications systems. This article describes the country's efforts since the late 1970s to develop satellite technology, particularly in the field of long-distance, broadcast education. Attention is also given to the role satellite communications can play in reaching remote, sparsely populated areas and in providing bilingual channels for ethnic minorities. The basis of the government's policy is a ‘Leasing for Transition’ programme arranged with Intelsat. But while emphasizing the value of cooperation and exchanges, the author also points to the headway made in indigenous technological development.     

Space and Copenhagen: The role of satellites

A half-day meeting on the role of satellites in combating climate change was added on to the eleventh annual European Interparliamentary Space Committee meeting in London, October 2009. Organized by the UK Parliamentary Space Committee and the European Space Policy Institute, the meeting's four speakers covered a range of issues, before engaging in discussion with questions from the floor. The main points raised are presented below.     

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.     

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.

Investigation of national policy shifts to impact orbital debris environments

Low earth orbit has become increasingly congested as the satellite population has grown over the past few decades, making orbital debris a major concern for the operational stability of space assets. This congestion was highlighted by the collision of the Iridium 33 and Cosmos 2251 satellites in 2009. This paper addresses the current state of orbital debris regulation in the United States and asks what might be done through policy change to mitigate risks in the orbital debris environment. A brief discussion of the nature of orbital debris addresses the major contributing factors including size classes, locations of population concentrations, projected satellite populations, and current challenges presented in using post-mission active debris removal to mitigate orbital debris. An overview of the current orbital debris regulatory structure of the United States reveals the fragmented nature of having six regulating bodies providing varying levels of oversight to their markets. A closer look into the regulatory policy of these agencies shows that, while they all take direction from The U.S. Government Orbital Debris Mitigation Standard Practices, this policy is a guideline with no real penalty for non-compliance. Various policy solutions to the orbital debris problem are presented, ranging from a business as usual approach to a consolidated regulation system which would encourage spacecraft operator compliance. The positive aspects of these options are presented as themes that would comprise an effective policy shift towards successful LEO conservation. Potential economic and physical limitations to this policy approach are also addressed.     

Ukrainian space policy — contributing to national economic development

Following Ukraine's 1991 declaration of independence and the disintegration of the USSR, Ukraine inherited a third of the Soviet Union's space industry. This paper presents an overview of the main features of Ukraine's current policy on the exploitation of this capability as a factor in the transformation of its economy. It illustrates how the policy is being realized in the areas of launch systems, Earth observation, satellite communications and international relations, and concludes that Ukraine's strengths in the space field are counterbalanced by obstacles which must be faced, both within the country and externally.     

Results of Kirari optical communication demonstration experiments with NICT optical ground station (KODEN) aiming for future classical and quantum communications in space

Bi-directional ground-to-satellite laser communication experiments were successfully performed between the optical ground station developed by the National Institute of Information and Communications Technology (NICT), located in Koganei City in suburban Tokyo, and a low earth orbit (LEO) satellite, the “Kirari” Optical Inter-orbit Communications Engineering Test Satellite (OICETS). The experiments were conducted in cooperation with the Japan Aerospace Exploration Agency (JAXA), and called the Kirari Optical communication Demonstration Experiments with the NICT optical ground station (or KODEN). The ground-to-OICETS laser communication experiment was the first in-orbit demonstration involving the LEO satellite. The laser communication experiment was conducted since March 2006. The polarization characteristics of an artificial laser source in space, such as Stokes parameters, and the degree of polarization were measured through space-to-ground atmospheric transmission paths, which results contribute to the link estimation for quantum key distribution via space and provide the potential for enhancements in quantum cryptography on a global scale in the future. The Phase-5 experiment, international laser communications experiments were also successfully conducted with four optical ground stations located in the United States, Spain, Germany, and Japan from April 2009 to September 2009. The purpose of the Phase-5 experiment was to establish OICETS-to-ground laser communication links from the different optical ground stations and the statistical analyses such as the normalized power, scintillation index, probability density function, auto-covariance function, and power spectral density were performed. Thus the applicability of the satellite laser communications was demonstrated, aiming not only for geostationary earth orbit-LEO links but also for ground-to-LEO optical links. This paper presents the results of the KODEN experiments and mainly introduces the common analyses among the different optical ground stations.     

Satellite communications and the Internet: implications for the outer space treaty

The speedily expanding Internet is in the process of transforming the technological, economic, and policy bases for nation-state regulation of telecommunications, including space-based satellite networks. Deployment of the packet-switched Internet has accelerated the liberalization of telecommunications markets and has led to far-reaching regulatory restructuring and policy shifts regarding state ownership and control of networks and information flows. As space-based GMPCS networks become integral parts of the globalizing Internet infrastructure, the state-centric legal paradigm requiring state “authorization and continuing supervision” of space activities by “non-governmental entities” stipulated under Article VI of the OST and associated treaties forming the outer space legal regime will be called increasingly into question. This paper examines the technological, economic/trade, and security issues that question whether the existing state-centric paradigm for regulating Internel-based GMPCS satellite systems will remain in legal phase with emerging liberalized regulatory regimes for terrestrial Internet-based infractructures.     

The role of the united nations in promoting international cooperation in peaceful uses of outer space

The Committee on the Peaceful Uses of Outer Space (COPUOS) was established in 1959 by the United Nations General Assembly in order to review and foster international cooperation in the peaceful uses of outer space and to consider legal issues arising from the exploration of outer space. Since its establishment, the Committee has addressed such issues as benefits from space activities, the definition and delimitation of outer space and the use of the geostationary orbit, implications of remote sensing, space sciences, space-based communications, navigation and meteorological systems, as well as use of nuclear power sources in outer space, space debris and spin-off benefits of space technology. At its session in 1996, a symposium on the ‘Utilization of micro- and small satellites for the expansion of low-cost space activities, taking into particular account the needs of developing countries’ was organized by COSPAR and IAF to complement discussions on this theme. It was noted at the symposium that the increasing number of small satellites, in particular the proposed introduction of multi-satellite ‘constellations’ at low orbits, would result in concentrations of satellite mass at certain regions of space around the Earth. Special provisions would be needed to minimize the probability of satellite breakups and collisions which might create more space debris and compromise the future of spaceflight.     

Telecommunications and the economic impact of communications satellites

This article provides several illustrations of the growing economic importance and scope of communications satellite service and discusses how rapid development of new telecommunications systems, particularly those that include communications satellite systems, serve as a major stimulant of economic growth. There is evidence that communications satellites are capable of making important economic contributions to developed and developing countries alike. The rapid proliferation of separate communications satellites, although stimulating economic growth, is giving rise to concerns about intersystem connectivity and saturation of the available radio frequencies in geosynchronous orbit. The growth of the communications satellite industry to an activity level of perhaps $10,000 million per annum by the mid-to-late-1980s could assist in the development of multipurpose space platforms that could minimize the problems created by satellite proliferation.     

We think we know where we are,but can anyone tell us where we are going? Has the European Union lost its way?

Using the various problems and delays in the Galileo satellite navigation programme as a metaphor for European leaders' incompetence and complacency in a wide range of other important fields, this viewpoint bemoans the lack of direction in both the European project and its space policy, the result of growing state nationalism and a neoliberal approach that has left the continent at the mercy of globalisation.     

Space solar power vs space communications

To meet the future needs of energy on Earth, the transmission of solar power from space is being extensively studied. Since the power station will occupy a position in the geostationary orbit and will use radio frequency spectrum for transmission of energy to Earth, the relative benefits of space solar power and space communications should be considered. The resource allocation of orbit-spectrum to a power station requires a sacrifice from space communications as they both utilize similar limited resources. The power station is to energy what communication is to information. While the cost of energy is going up, the cost of information processing, storage, sharing and transmission is decreasing. Also, increased means of communication are used as a measure of energy conservation. With the advent of computer communication and the Large Scale Integrated (LSI) microprocessors, the technique of multiple access, message switching and satellite switching can be cost-effectively combined. The computer-satellite communication will allow information resource sharing among large numbers of users besides the conventional application of space communications. Since space communication means work effectively in many other areas where ultimate energy use and conservation is possible, the space solar power will not be able to compete or substitute on the basis of equality and social benefits. But, as the transmission technology is similar for both areas, the R & D effort for solar power will certainly increase efficiency and reduce cost for space communications.     

Developing the next phase in NASAs satellite communications program

NASAs early efforts in satellite communications development brought confidence in space technology use for improved telecommunications. New, worldwide satellite communications systems have resulted, and are now on a commercial, self-sustaining operational basis. Since 1973, NASA has conducted hundreds of user experiments and demonstrated newer technology using ATS-1, -3, -6 and CTS. Now, projections show that the commercial demand will continue to increase, soon exceeding the current technology's capacity.As a result, U.S. Space Policy affirmed in 1978 that NASA should embark again on a research and development program for satellite communications with specific, characterized goals. The resulting plan's elements include $\text{30}\text{20}\text{GHz}$ Ka-band technology, extending the current work in advanced multi-beam antennas; a narrowband system and technology study that could lead to mobile and transportable communications developments; and studies of future uses of technology in communications. The program plan and its evolution are described, followed by a report of current progress and future expectations.     

Tracking and data relay satellite system: NASA's new spacecraft data acquisition system

The growth in NASA's ground network complexity and cost triggered a search for an alternative. Through a lease service contract, Western Union will provide to NASA 10 years of space communications services with a Tracking and Data Relay Satellite System (TDRSS). A constellation of four operating satellites in geostationary orbit and a single ground terminal will provide complete tracking, telemetry and command service for all of NASA's Earth orbital satellites below an altitude of 12,000 km. The system is shared: two satellites will be dedicated to NASA service; a third will provide backup as a shared spare; the fourth satellite will be dedicated to Western Union's Advanced Westar commercial service. Western Union will operate the ground terminal and provide operational satellite control. NASA's Network Control Center will provide the focal point for scheduling user services and controlling the interface between TDRSS and the rest of the NASA communications network, project control centers and data processing facilities. TDRSS single access user spacecraft data systems should be designed for efficient time shared data relay support. Reimbursement policy and rate structure for non-NASA users are currently being developed.     

Pakistan's space programme

Space research in Pakistan is conducted by the Pakistan Space and Upper Atmosphere Research Commission (Suparco). Suparco's programmes consist of the launching of sounding rockets and satellite applications, especially remote sensing and communications. Its long-term goals are to develop communications and remote sensing satellites and to launch lightweight scientific satellites in near-Earth orbits. To train its scientific staff at postgraduate level, Suparco is establishing an Aerospace Institute. The Commission is very active in international forums such as the UN COPUOS, Cospar, IAF and IUCN.

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.     

Towards an EU industrial policy for the space sector – Lessons from Galileo

The rise of the EU as an actor in the European and world space theatres, in its various roles as initiator, owner and operator of large-scale programmes such as Galileo and GMES, has raised a number of questions with regard to industrial policy. Based on the experiences from the Galileo programme's procurement round in the Full Operational Capability (FOC) phase and on the present discussions on space industrial policy within the EU, this paper argues that, whereas the EU's political ambitions in space have been discussed and become reasonably well defined, the specific policy tools and legal instruments to put them into practice are far from complete. First, an unequivocal industrial policy for the space sector needs to be defined that reconciles the Union's political ambitions with the economic specificities of the space sector. At present, this is a work in progress, with opinions diverging between member states. Second, both logically and temporally, these policy decisions need to be translated into legal instruments that allow their implementation. This implies the development of made-to-measure funding instruments and procurement rules. We conclude by emphasising the need for a sector-specific industrial policy as an integral part of the EU's space policy.
