Arbitration in Space-Related Disputes: a Survey of Industry Practices and Future Needs
70th International Astronautical Congress (IAC), Washington D.C., United States, 21-25 October 2019. Copyright ©2019 by the authors. All rights reserved. IAC-19,E7,2,3,x50661 Arbitration in Space-related Disputes: A Survey of Industry Practices and Future Needs Viva Dadwala*,**, Eytan Tepperb** a Faculty of Law, McGill University, 3644 Peel St, Montreal, Quebec H3A 1W9, [email protected] b Institute of Air & Space Law, McGill University, 3690 Peel Street Montréal, Québec, Canada H3A 1W9, [email protected] * Corresponding Author ** Both these authors contributed equally to this work Abstract To better understand the viability of arbitration in space-related disputes, we designed a survey that examines the use of arbitration clauses in contracts used by space companies, and if the use thereof is mandatory. More specifically, the survey gathers data on contracting parties’ preferred seats of arbitration, arbitration institutions, selection process for arbitrators, and choice of procedural and substantive rules. The survey also captures actual use of arbitration within space related disputes by collecting data on how often such arbitration clauses have been invoked and the number of disputes ultimately resolved by arbitration. Finally, the survey solicits industry preferences for the future development of arbitration as a form of dispute resolution in the space sector. The survey is built in a way that allows break down of results and comparing segments, inter alia, based on the type of contract (e.g., launch contract, insurance contract, investment contract, contract for supply of parts or services). The results of the survey will expose the demand for arbitration and the successes and barriers for the use thereof. -
Introduction to International Radio Regulations
ICTP Lecture Notes INTRODUCTION TO INTERNATIONAL RADIO REGULATIONS 3 – 21 February 2003 Editor S.M. Radicella The Abdus Salam ICTP, Trieste, Italy INTRODUCTION TO INTERNATIONAL RADIO REGULATIONS - First edition Copyright © 2003 by The Abdus Salam International Centre for Theoretical Physics The Abdus Salam ICTP has the irrevocable and indefinite authorization to reproduce and disseminate these Lecture Notes, in printed and/or computer readable form, from the author. ISBN 92-95003-23-3 Printed in Trieste by the Abdus Salam ICTP Publications & Printing Section Introduction to International Radio Regulations iii Introduction to International Radio Regulations v Introduction It is a pleasure for me to introduce these notes, which contain an overview of basic problems of the International Radio Regulations. Access to the existing information infrastructure, and to that of the future Information Society, depends critically on radio, especially in poor, remote and sparsely populated regions with under-developed telecommunication infrastructure. How the spectrum of radio frequencies is regulated has profound impact on the society, its security, prosperity, and culture. The radio regulations represent a very important framework for an adequate use of radio and should be known by all of those working in the field. The author of these notes Professor Ryszard (Richard) Struzak, Co-Director of the series of schools on Radio Use at the Abdus Salam International Centre for Theoretical Physics (ICTP), is very well qualified to present the issue having been Vice-Chair of the Radio Regulations Board of International Telecommunication Union (ITU), a specialized agency of the United Nations (UN). He is also former Co- Chair of the Spectrum Management/ Utilization Working Group of International Union of Radio Science (URSI). -
Positioning Using IRIDIUM Satellite Signals of Opportunity in Weak Signal Environment
electronics Article Positioning Using IRIDIUM Satellite Signals of Opportunity in Weak Signal Environment Zizhong Tan, Honglei Qin, Li Cong * and Chao Zhao School of Electronic and Information Engineering, Beihang University (BUAA), Beijing 100191, China; [email protected] (Z.T.); [email protected] (H.Q.); [email protected] (C.Z.) * Correspondence: [email protected]; Tel.: +86-1381-0629-638 Received: 9 December 2019; Accepted: 25 December 2019; Published: 27 December 2019 Abstract: In order to get rid of the dependence of the navigation and positioning system on the global navigation satellite system (GNSS), radio, television, satellite, and other signals of opportunity (SOPs) can be used to achieve receiver positioning. The space-based SOPs based on satellites offer better coverage and availability than ground-based SOPs. Based on the related research of Iridium SOPs positioning in the open environment, this paper mainly focuses on the occluded environment and studies the Iridium SOPs positioning technique in weak signal environment. A new quadratic square accumulating instantaneous Doppler estimation algorithm (QSA-IDE) is proposed after analysing the orbit and signal characteristics of the Iridium satellite. The new method can improve the ability of the Iridium weak signal Doppler estimation. The theoretical analysis and positioning results based on real signal data show that the positioning based on Iridium SOPs can be realized in a weak signal environment. The research broadens the applicable environment of the Iridium SOPs positioning, thereby improving the availability and continuity of its positioning. Keywords: signals of opportunity positioning; Iridium; weak signal; instantaneous Doppler 1. Introduction The new methods for receiver positioning based on abundant and various frequency signals have emerged in recent years. -

ABSTRACT United Kingdom’s Brexit from the European Union implies restricted access to the European Global Navigation Satellite System (GNSS) System - Galileo; with no access to the secured and encrypted signal used for defense and government purposes, which is restricted to European Union (EU) members. To mitigate this issue, the United Kingdom can, as a matter of urgency, launch a payload on a national military Communications Satellite to provide Navigation Overlay Services for the United Kingdom territory, surrounding waters and neighboring ally countries to meet the requirements of: Defense systems, Aviation, Maritime requirements and the effectiveness of Location-based Services for Emergencies and Crisis management etc. This paper describes the design of a navigation overlay service system as a hoisted payload on a national satellite and the required supporting ground infrastructure, highlighting various applications, services and solutions. Keywords: Brexit, Communications Satellite, Defence, European Union (EU), Galileo, GNSS, Military, Precision Point Positioning, SBAS. 1 INTRODUCTION TO GLOBAL NAVIGATION SATELLITE SYSTEM (GNSS) The United States Global Positioning System (GPS) marked the beginning of Global Navigation Satellite Systems (GNSS). After the First World War, radio time signals offered alternative technology for determination of the Greenwich Time line and thus longitude at sea. -

DYNAMICAL PROPERTIES OF THE MOLNIYA SATELLITE CONSTELLATION: LONG-TERM EVOLUTION OF THE SEMI-MAJOR AXIS J. DAQUIN, E.M. ALESSI, J. O'LEARY, A. LEMAITRE, AND A. BUZZONI Abstract. We describe the phase space structures related to the semi-major axis of Molniya-like satellites subject to tesseral and lunisolar resonances. In particular, the questions answered in this contribution are: (i) we study the indirect interplay of the critical inclination resonance on the semi-geosynchronous resonance using a hierarchy of more realistic dynamical systems, thus discussing the dynamics beyond the integrable approximation. By introducing ad hoc tractable models averaged over fast angles, (ii) we numerically demarcate the hyperbolic structures organising the long-term dynamics via Fast Lyapunov Indicators cartography. Based on the publicly available two-line elements space orbital data, (iii) we identify two satellites, namely Molniya 1-69 and Molniya 1-87, displaying fingerprints consistent with the dynamics associated to the hyperbolic set. Finally, (iv) the computations of their associated dynamical maps highlight that the spacecraft are trapped within the hyperbolic tangle. This research therefore reports evidence of actual artificial satellites in the near-Earth environment whose dynamics are ruled by manifolds and resonant mechanisms. The tools, formalism and methodologies we present are exportable to other region of space subject to similar commensurabilities as the geosynchronous region. 1. Introduction The present manuscript is part of a recent series of papers [1, 6] dedicated to astrodynamical properties of Molniya spacecraft. It is well-known that the Molniya orbit provides a valuable dynamical alternative to the geosynchronous orbit, suitable for communication satellites to deliver a service in high-latitude countries, as it is actually the case for Russia. -
