International space launch notification and data exchange

As missile and space launch technology continue to proliferate around the world, nations will benefit from increased transparency to mitigate the potentially strategic consequences of early warning false alarms or misinterpretations. Previous false alarms and risk mitigation steps taken by the United States and the former Soviet Union and Russia are examined. Two pre-launch notification initiatives, the bilateral US/Russia Joint Data Exchange Center and the multilateral Hague Code of Conduct, offer means to further build confidence among spacefaring nations and enhance strategic stability. Pragmatic recommendations are offered to strengthen the emerging pre-launch notification regime.     

Implications of previous space commercialization experiences for the reusable launch vehicle

In evaluating the prospects for the development of a commercially viable RLV, it may be useful to examine ’lessons learned‘ from previous space commercialization efforts– both those that succeeded and those that did not. It can be argued that several distinct streams of market and technological development may have to converge for successful commercialization of space systems to occur. Factors influencing the prospects for commercialization include the size and growth rate of the potential customer base, the extent to which a governmental customer exists to underpin the market, the development of associated ’value-added‘ markets, the stability of governmental policies, the availability of enabling or enhancing infrastructure, the levels of technological and business risk, and the degree to which competitive markets exist. This paper examines two previous space commercialization experiences, evaluates the relative importance of the various factors that influence the prospects for success of commercialization efforts, and assesses the implications of those factors for the commercial viability of the proposed RLV.

Technology control regimes and the globalization of space industry

This paper provides theoretical underpinnings for further discussions on the future direction of the international aerospace community in an era of globalization. It points out that changes in the international distribution of resources are placing strains on the basic operating principles of the current technology control regime, but at this stage the social groupings do not appear to be in place to overturn the current paradigm. Instead, this paper suggests that current operating principles could be modified in order for the current regime to keep pace with globalization. These changes would include: (1) a shift in the monitoring mechanism of the Missile Technology Control Regime (MTCR) requiring looser supervision but greater transparency; (2) greater inclusion of private industry as a stakeholder in MTCR proceedings; and (3) much more focus on the list of prescribed technologies to include only those which are most critical to the development of military missiles.     

US government policy - the major factor shaping the international commercial space launch marketplace

In this Viewpoint — an edited version of a statement made to the US House Committee on Science's Subcommittee on Space and Aeronautics' hearing on ‘US launch strategy’ — the President of Arianespace, Inc analyses the overriding importance of US government policies and executive decisions on the shaping and behavior of the international market in commercial space launch services. Chief among these is the overruling of commercial imperatives by foreign policy and national security interests and the consequent regular intervention of the US government in launch decisions. The ability of Arianespace successfully to compete in a market severely distorted as a result of these interventions, including the encouragement of joint ventures between US and Russian or Ukrainian companies, is explained.     

The impact of US export controls on the Canadian space industry

The International Traffic in Arms Regulations (ITAR) govern the export of defense-related technologies and services from the USA. In 1999 Canada's exemption to ITAR was suspended because of American objections over some Canadian companies retransferring US technology to third countries. This paper is a first attempt to quantify the impact of ITAR on the Canadian space industry. Thirty-two space-related companies were contacted and a total of nine responses were received, representative of around 60% of the Canadian space industry in terms of workforce and revenue. According to the results, the Canadian space industry has been relatively effective in meeting the challenges imposed by ITAR. However, these workarounds do not diminish its negative impacts, particularly with respect to cost and schedule. It is expected that ITAR will continue to affect the Canadian space industry, as no near-term relief from the current regulatory environment is on the horizon.     

Observations of the Auroral Kilometric Radiation onboard the Interball-1 satellite in 1995–1997

Results of two-year (August 1995–July 1997) continuous observations of the auroral kilometric radiation (AKR) in the AKR-X experiment on board the high-apogee Interball-1 satellite are presented. Observations were carried out in the minimum of solar activity in a frequency range of 100–1500 kHz. The most effective detections of AKR occurred near the maximum of its spectrum at a frequency of 252 kHz and also at a frequency of 500 kHz. The data obtained made it possible to study in more detail the character of AKR global directivity, its frequency dependence, and some other parameters of the emission. These data are interpreted qualitatively in the context of the emission mechanism caused by cyclotron maser instability.     

Corporate mergers - Lifeline for the space industry

The world's major space companies have undergone continual evolution, through a process of mergers and acquisitions, since their creation from their aerospace parents. Although much of this evolution occurred in the early years of the Space Age, the process seems to have become particularly dynamic in the 1990s, as companies have striven to become ever more competitive in an increasingly global business environment. This article reviews some of the most important mergers and traces the recent development of the world's leading space contractors.

First results of investigating the space environment onboard the Universitetskii-Tatyana satellite

The complex of scientific pay load installed onboard the research and educational Universitetskii-Tatyana microsatellite of Moscow State University is described. The complex is designed to study charged particles in the near-earth space and ultraviolet emissions of the atmosphere. Data of the measurements of charged particle fluxes in the microsatellite orbit are presented, spectra are calculated, and the dynamics of penetration boundaries for protons of solar cosmic rays (SCR) during geomagnetic disturbances in 2005 is investigated. Intensities of the ultraviolet emission are measured in the entire range of variation of the atmospheric irradiation, as well as intensities of auroras in the polar regions of the Northern and Southern hemispheres. The experimental data on flashes of ultraviolet radiation (transient light phenomena in the upper atmosphere) are considered, and some examples of oscillograms of their temporal development and their distribution over geographical coordinates are presented.

Competitiveness of the European space industry. Lessons from Europe's role in NATO

This article aims to illustrate how the predominant role of the US military space capabilities within NATO adversely affects the European space industry's competitiveness and performance, as compared with the USA space industry. Thus, first the intra-NATO specialization is illustrated, followed by an analysis of the economics of the space industry. The connection is made through an economics model whose results verify the hypothesis, and predicts that the recent commitment by the WEU to military space can improve the position of the European space industry, especially if followed by close cooperation between the WEU and ESA.     

Secular evolution of rotary motion of a charged satellite in a decaying orbit

An electrostatically charged Earth satellite whose orbit is decaying due to the Earths oblateness is considered. Secular perturbations of the orbit are taken into account: they are caused by the second zonal harmonic of the geopotential. These perturbations represent deviations of the longitude of the ascending node and perigee argument, the orbit form being invariable and the orbit inclination to the equatorial plane being constant. The attitude rotary motion of the satellite under the action of perturbing moments of the gravitational and Lorentz forces is studied. The magnetic field of the Earth is taken in a quadrupole approximation. The evolution of the satellites rotary motion is investigated on the basis of new differential equations in s-parameters specially constructed for this purpose. Using the method of averaging, basic regularities of the secular evolution of rotary motion of a screened satellite are revealed. It is found that the rotary motion of a charged satellite essentially depends on the quadrupole component of the geomagnetic potential.__________Translated from Kosmicheskie Issledovaniya, Vol. 43, No. 2, 2005, pp. 111–125.Original Russian Text Copyright © 2005 by Tikhonov.     

Whose jurisdiction over the US commercial satellite industry? Factors affecting international security and competition

Within a global economy, export controls play a large role in hindering the proliferation of high technology. A company operating in a country that operates under more strict export controls than others is at a serious disadvantage in competing. This has been the case for commercial satellite (comsat) manufacturers in the USA since 1999, when Congress redefined comsats and all technologies associated with them from a dual-use export under the jurisdiction of the Department of Commerce to a munitions export that falls under the jurisdiction of the Department of State. Following this, there was a drastic drop in the market share of US comsat manufacturers in comparison to European manufacturers, who continued to define satellites as a dual-use technology. This paper examines the various factors that have affected US industry competitiveness and tackles the question of whether or not it continues to make sense to keep comsats under the more restrictive International Traffic in Arms Regulations (ITAR) controls. To accomplish this, comsats are subjected to a litmus test created by George Zaphiriou in 1992 to determine whether a technology should be placed under ITAR controls.

Russian space programmes and industry: Defining the new institutions for new conditions

The aim of this article is to define the major elements of the institutional design process for the Russian rocket and space industry, a process which must take account of the changed economic conditions in the country and provide for the industry's integration into the wider national economy. The article does this by demonstrating the features that need to be understood, highlighting the problems that need to be resolved, and arguing that an institutional design process will have to be based on compromise and accommodation of all the different actors involved. The article deals with a number of particular problems challenging the managers and methodologists of the Russian national space programme of today.
