Executive Summary of the ICAO Position for ITU WRC-15 Radio
Executive Summary of the ICAO Position for ITU WRC-15 Radio frequency spectrum is a scarce natural resource with finite capacity for which demand is constantly increasing. The requirements of civil aviation as well as other spectrum users continue to grow at a fast pace, thus creating an ever-increasing pressure to an already stretched resource. International competition between radio services obliges all spectrum users, aeronautical and non- aeronautical alike, to continually defend and justify retention of existing or addition of new frequency bands. The ICAO Position aims at protecting aeronautical frequency spectrum for all radiocommunication and radionavigation systems used for ground facilities and on board aircraft. The ICAO Position addresses all radioregulatory aspects on aeronautical matters on the agenda for the WRC-15. The items of main concern to aviation include the following: identification of additional frequency bands for the International Mobile Telecommunications (IMT). Under this agenda item, the telecommunications industry is seeking up to 1200 MHz of additional spectrum in the 300 MHz to 6 GHz range for mobile and broadband applications. It is expected that a number of aeronautical frequency bands will come under pressure for potential repurposing, especially some of the Primary Surveillance Radar (PSR) bands. Existing frequency allocations which are vital for the operation of aeronautical very small aperture terminal (VSAT) ground-ground communication networks, especially in tropical regions, are also expected to come under pressure. Due to decisions made by a previous WRC, this has already become a problematic issue in Africa. WRC-15 agenda items 1.1 and 9.1.5 refer; potential radioregulatory means to facilitate the use of non-safety satellite service frequency bands for a very safety-critical application, the command and control link for remotely piloted aircraft systems (RPAS) in non-segregated airspace. -

INDIANA LAW JOURNAL Volume 44 Spring 1969 Number 3 THE LEGAL ORDERING OF SATELLITE TELECOMMUNICATION: PROBLEMS AND ALTERNATIVES DELBERT D. SMITHt The use of satellites in outer space to provide a means of transmission for international telecommunication could be viewed as simply a tech- nological advancement neither necessitating basic structural changes in the international control institutions nor requiring alteration of the control theories designed to regulate unauthorized transmissions. How- ever, the magnitude of the changes involved, coupled with increased governmental concern, has resulted in a number of politico-legal problems. It is the purpose of this article to examine on several levels of analysis the implications of utilizing satellites as a means of telecom- munication transmission. Introductory material on the development of communications satellite technology stresses the need for international organization and co-operation to oversee the launching and maintenance of a global communications system and indicates the pressures for the implementation of control measures over transmissions originating in outer space. -
Space Science and Meteorology Spectrum Allocations in the UK
Introduction ‘Space science’ is an umbrella term that covers both Earth observation and space related scientific research. Earth observation (EO) satellites observe the earth and its atmosphere, using visible light or radio spectrum from a unique vantage point. The information it provides is used for a wide range of purposes including weather forecasting, environmental monitoring, climate change research as well as a number of commercial activities. Radio astronomy and space research contribute to our knowledge of space and the evolution of the universe. The following services fall under this category: • Earth Exploration Satellite Service (EESS) Space Research Service (SRS) Space Operation Service (SOS) Radio Astronomy Service (RAS) Meteorological Satellite Service (MetSat) Meteorological Aids Service (Met-Aids) Radiolocation Service Note: this only for wind profiler and weather radars) Standard Time and Frequency signals) These services can be split in two broad categories: passive services (RAS, EESS and Space Research Service), that measure naturally- occurring radiation often at very low power levels. This information provides useful data to help further understand the Earth and universe. The frequency bands are often determined by the specific physical properties being investigated (e.g. molecular resonance). active services that make use of a variety of technologies (e.g. radiodetermination) to carryout measurements, observations or transfer the collected data. These active applications are relatively less sensitive to interference compared to passive sensors. Given the low levels of radiation being monitored these services often use very sensitive receivers. In most cases the equipment is not able to discriminate between these natural radiations and man-made radiations. For this reason, a number of bands have been harmonised across the world for the use by passive services only. -
International Air Transport Association Position for the World Radiocommunication Conference (WRC - 12)
International Air Transport Association Position for the World Radiocommunication Conference (WRC - 12) September 2009 Objectives of IATA Position The IATA Position) for the World Radiocommunication Conference (WRC 12) seeks to guarantee appropriate, secure radio spectrum to support current and planned CNS technologies and systems essential to meeting future growth in a safe and efficient manner. Due to the safety and global harmonization of airline operations, allocations for such radio spectrum are made at WRC’s, the outcomes of which have international treaty status. IATA believes such international coordination is essential and opposes the application of new, more market driven, regulatory measures to the spectrum aviation uses. The broad objectives of the IATA position are: • to maintain protection for the spectrum used for aeronautical radiocommunication and radionavigation systems required for current and future safety-of-life applications; • to ensure that spectrum is available for new technologies; • to ensure that the application of new regulatory measures does not impact on global operations or result in social or economic penalty to aviation without providing benefit. IATA has 226 member airlines carrying 93% of world’s international scheduled traffic (Available Seat Kilometres). In 2008, IATA’s members carried 1.6 billion passengers (scheduled) of which 708 million were international and 42.3 million tones of freight of which 28 million tonnes were international Introduction Aviation uses globally harmonised spectrum allocations for communications, navigation and surveillance in order to provide a safe and efficient global transport system. Hence the spectrum used by aviation must be free from harmful interference to guarantee the integrity of its systems. -

RSPG Sub-Group on Scientific Use of Radio Spectrum
Progress report RSPG OPINION on ¨a coordinated EU Spectrum approach for scientific use of radio spectrum¨ 1. Introduction This paper represents the Radio Spectrum Policy Group’s (RSPG) progress report to the request from France and The Netherlands for an Opinion on spectrum used by scientific services. (document RSPG05-67 and RSPG 05-82). Many fields of science depend on the use of radio spectrum. This spectrum could also be used for other purposes, which in certain cases leads to pressure on the spectrum used by the scientific community. These developments have led to concerns about the long-term availability of spectrum for scientific use. Although these alternative applications may represent significant economic value, scientific usage of spectrum also has significant social and economic benefits. The RSPG agreed to formulate an opinion on the scientific use of spectrum in order to get an overview of all important aspects of the spectrum-based activities of the scientific community and to issue recommendations. 2. Overview of Scientific Use 2.1 Introduction Spectrum is used by several scientific services. These services use radio emissions to register naturally occurring physical phenomena or to communicate information between different locations. The following services are identified in the Radio Regulations: the Meteorological Aids Service, the Earth Exploration Satellite Service (EESS), the Meteorological-Satellite Service, the Space Research Service (SRS), and the Radio Astronomy Service (RAS). Also the Space Operation Service, the Radiolocation Service (RLS) and the Radionavigation Satellite Service are used for scientific applications1. This chapter gives a description of the various scientific activities. It is to be noted that these activities do not always coincide with the definitions of services used by the ITU in the Radio Regulations. -

WMO Position Onwrc-15 Agenda (March 2014)
WORLD WEATHER WATCH COMMISSION FOR BASIC SYSTEMS WMO Position onWRC-15 Agenda (March 2014) 1 Introduction Timely warning of impending natural and environmental disasters, accurate climate prediction and detailed understanding of the status of global water resources: these are all critically important everyday issues for the global community. National Meteorological and Hydrological Services (NMHS) around the world are responsible for providing this information, which is required for the protection of the environment, economic development (transport, energy, agriculture,..) and the safety of life and property. Radio-frequencies represent scarce and key resources used by National Meteorological and Hydrological Services to measure and collect the observation data upon which analyses and predictions, including warnings, are based or processed, and to disseminate this information to governments, policy makers, disaster management organisations, commercial interests and the general public. Nowadays radio-based remote sensors (active and passive) are the main tools for environment and climate monitoring, disaster prediction, detection and mitigating negative effects of disasters. These sensors obtain environmental data by measuring level and parameters of natural and artificial radio waves that inherently contain information about the environment with which they have been in contact. Terrestrial and space-born remote sensing applications form the backbone of the WMO Integrated Global Observing System. WMO information systems also make extensive use of radiocommunication systems and radio- frequency spectrum, and although they are also using commercially provided services such as communication satellites, meteorological related radiocommunication systems are an essential and indispensable component of WMO’s critical data collection and distribution systems (e.g. Earth-to- space and space-to-Earth transmissions). -
