Abstract:
The political problems surrounding the provision of a commercial television service to viewers in remote areas first surfaced publicly in the 1984 Australian Broadcasting Tribunal (ABT) Inquiry into Satellite Program Services (SPS). The Australian Broadcasting Corporation (ABC) had already worked out its Homestead and Community Broadcasting Satellite Service (HACBSS) scheme for bringing ABC TV to remote areas via the satellite, but there remained considerable uncertainty as to the provision of commercial television to remote areas. The Minister for Communications asked the Tribunal to examine this issue in the course of its Inquiry.

Abstract:
Satellite for next generation mobile satellite communication service with small personal terminal requires onboard antenna with very large aperture reflector larger than twenty meters diameter because small personal terminal with lower power consumption in ground base requires the large onboard reflector with high antenna gain. But, large deployable antenna will deform in orbit because the antenna is not a solid dish but the flexible structure with fine cable and mesh supported by truss. <br><br> Deformation of reflector shape deteriorate the antenna performance and quality and stability of communication service. However, in case of digital beam forming antenna with phased array can modify the antenna beam performance due to adjustment of excitation amplitude and excitation phase. If we can measure the reflector shape precisely in orbit, beam pattern and antenna performance can be compensated with the updated excitation amplitude and excitation phase parameters optimized for the reflector shape measured every moment. <br><br> Softbank Corporation and National Institute of Information and Communications Technology has started the project "R&amp;D on dynamic beam control technique for next generation mobile communication satellite" as a contracted research project sponsored by Ministry of Internal Affairs and Communication of Japan. <br><br> In this topic, one of the problem in vision metrology application is a strong constraints on geometry for camera arrangement on satellite bus with very limited space. On satellite in orbit, we cannot take many images from many different directions as ordinary vision metrology measurement and the available area for camera positioning is quite limited. Feasibility of vision metrology application and general methodology to apply to future mobile satellite communication satellite is to be found. Our approach is as follows: <br><br> 1) Development of prototyping simulator to evaluate the expected precision for network design in zero order and first order <br><br> 2) Trial measurement for large structure with similar dimension with large deployable reflector to confirm the validity of the network design and instrumentation. <br><br> In this report, the overview of this R&amp;D project and the results of feasibility study of network design based on simulations on vision metrology and beam pattern compensation of antenna with very large reflector in orbit is discussed. The feasibility of assumed network design for vision metrology and satisfaction of accuracy requirements are discussed. The feasibility of beam pattern compensation by using accurately measured reflector shape is confirmed with antenna pattern simulation for deformed parabola reflector. If reflector surface of communication satellite can be measured routinely in orbit, the antenna pattern can be compensated and maintain the high performance every moment.

Abstract:
This article presents a comparative analysis of News Corporation’s entry strategy and rise to dominance in the British and Italian television markets through its satellite pay-TV operations, BSkyB and Sky Italia respectively. As well documented, News Corporation’s strategy in the UK has been heavily dependent on Rupert Murdoch’s cultivation of political connections. By contrast, in Italy Murdoch has been unable to influence local politics to further his business interests, as evidenced by the several regulatory setbacks suffered by Sky Italia. Thus, in order to explain News Corporation’s success in Italy, this article argues that emphasis must be placed primarily on the managerial and financial resources that the company has been able to mobilize. The analysis aims at broadening our understanding of how News Corporation operates in different national contexts, and should also prove valuable for the broader question concerning the shifting balance of power between transnational and national actors in today’s globalizing media landscape.

Abstract:
Malaysia had in the past sent two remote sensing satellites to orbit by collaborating with foreign space companies to build homegrown capacities for space technology development. At the educational institutions, a pico-satellite development program would be an ideal first step to establish such capacity as students could gain the experience and know-how through the complete cycle of designing, building and testing a satellite. As it is now, some of their overseas counterparts have already succeeded in running CubeSat programs due to strong support from kit manufacturers and their national space agencies. However, the cost to purchase such kits could be discouraging and National Space Agency (ANGKASA) recognises the needs to initiate some designs that could be used or referred to for further development or expansion. In this paper, a hardware design of On-Board Data Handling (OBDH) board using PIC Microcontroller is presented. OBDH is a main subsystem which controls all subsystems in the satellite. It provides a series of important services like command, telemetry, data communication, data acquisition, process, storage and management. The PIC Microcontroller made by Microchip Corporation is chosen as it is widely used by the industry and academia in Malaysia. The 16-bit PIC24 microcontroller has been recognized as a suitable part due to its performance, memory, peripherals, cost effective solutions as well as availability. The method used in designing the OBDH in this pico-satellite is first based on a main mission to investigate ionospheric effect on GPS signal transmission. Other considerations taken are that the parts used should be of commercial off the shelf product and having its own development board for ease of testing. The expected result would be the successful arrangement of all required parts in limited pico-satellite’s size and the accomplishment in achieving the satellite’s missions through simulation.

Abstract:
The Radiodetermination Satellite Service (RDSS) provides radiolocation and limited communication for users of aeronautical, marine and terrestrial vehicles. A system of the RDSS is being developed in the United States by the Geostar Corporation (Rothblatt, 1988). In this system signals from a control center are transmitted to transceivers on users’ vehicles through one of a series of two or three satellites spaced along the geostationary orbit, and responses are received through each of these satellites. If three satellites are used, locations of vehicles can be determined from the measured times of transmission from the control center to the user and back via different satellite paths. If two satellites are used the timing data must be supplemented by information such as altitude data from a terrain map, or an altimeter reading from the user’s vehicle, which can be encoded in the response transmitted back. Computation of the vehicle location is performed at the control center. The equipment at the vehicle can be relatively simple since its basic function is that of a transponder, and intervention by the vehicle operator is not necessarily required. However, provision can also be made for the inclusion of short coded messages from the vehicle, so the unit on the vehicle is usually referred to as a transceiver. The system is designed to meet the needs of various users; for example, trucking companies which must periodically monitor the locations of vehicles in a widely distributed fleet. Position information can be relayed to the company headquarters as well as to the vehicle operator. The role played by the central control computer in determining the locations requires that all vehicles using the service identify themselves by a transmitted code. Thus developers and operators of RDSS systems can lease their services to vehicle users.

Abstract:
The impact of industrialization, on natural resources, human health and environment was not clear till 1960s. Rachel Carson for the first time in 1962 raised important questions about human impact on nature in her book, Silent Spring. With the growing awareness towards sustainable<br />development, industries and corporations have a major role in environmental degradation and protection thereof. In the past, accounting theories emphasized primarily on financial performance. This awareness<br />on sustainable development is visible through varied environmental<br />management mechanisms practiced amongst companies across the world. Environmental concerns are addressed by corporate giants through identification and estimation of environmental costs, benefits, investments, assets and liabilities into main stream accounting and reporting practices, for varied managerial decisions. These focused environmental efforts have sharpened and improved the global reporting<br />standards. In India, the incorporation of environmental costs and benefits<br />into mainstream financial reporting is at its nascent stage at present - but it is certain to grow. Indian companies have not yet developed a holistic approach to environmental reporting, as there is lack of environmental reporting guidelines. On the other hand environmental awareness among<br />Indian stakeholders gets strengthened with advancement in communication technology. High propensity of environmental awareness ensures a more cautious approach among Indian corporations to be environmentally responsible. With the advancement of information and communications technologies, global corporate information disclosures<br />have been on rise through the medium of internet, as confirmed by various recent national and international surveys. This research has observed that Indian companies follow diverse reporting practices on the internet viz., stand alone environmental reporting (satellite accounts) or<br />reporting along with the Annual/Financial Reports, or Sustainability Reporting.

Abstract:
Monitoring and measurement of urban growth pattern with the help of urban-rural gradient and spatial metrics are gaining significant importance in recent times. Rapid and unplanned urban growth has a great impact on natural resources, local ecology, forestry and infrastructure. Temporal satellite data, gradient analysis and landscape metrics of urban landscapes will help to evolve appropriate strategies for integrated planning and sustainable management of natural resources. This communication focuses on spatiotemporal patterns of land use dynamics of Howrah Municipal Corporation (HMC), India and its surroundings with six buffer zones of 2kms. Analysis has been carried out on HMC using temporal remote sensing data. HMC has been used to identify the changes in the gradient of urban to peri-urban and rural regions. Further, the entire study area has been divided into eight zones radiated from city center based on directions. Different landscape metrics have been computed for each zone which helps to understand the spatiotemporal patterns and associated dynamics of the landscape at local levels.

Abstract:
Abstract. The occurrence of sporadic E (Es) layers has been a hot scientific topic for a long time. The GNSS (global navigation satellite system)-based radio occultation (RO) has proven to be a powerful technique for detecting the global Es layers. In this paper, we focus on some cases of complex Es layers based on the RO data from multiple missions processed in UCAR/CDAAC (University Corporation for Atmospheric Research (UCAR) the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) Data Analysis and Archive Center (CDAAC)). We first show some examples of multiple Es layers occurred in one RO event. Based on the evaluations between colocated simultaneous RO events and between RO and lidar observations, it could be concluded that some of these do manifest the multiple Es layer structures. We then show a case of the occurrence of Es in a broad region during a certain time interval. The result is then validated by independent ionosondes observations. It is possible to explain these complex Es structures using the popular wind shear theory. We could map the global Es occurrence routinely in the near future, given that more RO data will be available. Further statistical studies will enhance our understanding of the Es mechanism. The understanding of Es should benefit both Es-based long-distance communication and accurate neutral RO retrievals.

Abstract:
From the very beginning of the space activity in the middle of the XX cen tury the whole of it was considered mostly from the point of view of the military use of outer space. The only subjects of the space activity were states. All legal regulation of the activity was formatted by states. Both responsibility and liability for all activity were laid down upon states whoever was busy with the activity. Over time as technology advanced the outer space has become a place of the so calledactionoriented kinds of the use of the space. These are tele- and radio emission; the access to the Web; collection of meteorological and ecological data; communication and traffic, as well as remote sensing of the surface of the Earth and its subsoil. Practically all action-oriented kinds of the use of the space are made by means of the artificial satellites, the number of these active in the space is now estimated as about 2000. The space activity turned out to be quite profitable, so that it became an object of big investments. Naturally significant capitals of private business began to flow into outer space. Multinational corporations got interested in the space activity as well. Lately private companies began to pay attention to comets and asteroids since real technical opportunities appeared to develop their natural resources. A peculiar feature of these celestial bodies is, that some minerals are there quite pure so that the development might be much more profitable than on the Earth. But the consequences of the development are vague. The main document of the space law, the Treaty on the principals of space activity 1967 fully forbids national appropriation of space and celestial bodies.

Abstract:
Using the specific case of Rupert Murdoch's satellite operations, this thesis examines changes and trends in U.S. and Chinese satellite media policies under the diffusion of neoliberal globalization. Over the last two decades, the landscape of the global media market has been transformed by the force of transnational media conglomerates coupled with unprecedented technological innovation, including satellite telecommunications. Murdoch's satellite operations in the U.S. and China were synchronous with this process and therefore illustrate the trajectories of these two countries' media policies under different ideologies. This historical case study, which covers 1983 to the end of 2006 in the U.S. and 1993 to June 2008 in China, demonstrates that, in order to strengthen political power and capital power, both the U.S. and Chinese media industries are going forward to corporatism in two different ways.

Abstract:
This chapter examines the rise and fall of the “radio geographies” of the North and, with them, of the relationship between Northern nature and shortwave radio disruptions in Canada. It focuses on maps created around the Canadian Broadcasting Corporation (CBC)’s shortwave transmissions and their place in the large-scale state initiatives of the 1950s and 1960s. These geographies defined the failure of radio broadcasts according to a specific human geography of the North, a spatial distribution of radio transmitters, and a natural order of high-northern latitudes. That fallibility, in turn, was used to define the North as a region. Government officials envisioned shortwave radio as a medium naturally suited to the customs and culture of indigenous people. In the late 1960s, satellite communications, which promised to overcome radio disruptions, were seen as a threat not only to indigenous culture but to the definition of the region itself.

Abstract:
Today we call many things “virtual.” Virtual corporations connect teams of workers located across the country. In leisure time, people form clubs based on shared interests in politics or music, without ever meeting face-to-face. Even virtual romances flourish through electronic mail. All sorts of hybrid social realities have sprung up on fax machines and computers, cellular telephones and communication satellites. Yet most of these “virtual realities” are not, in the strict sense of the term, virtual reality. They are pale ghosts of virtual reality, invoking “virtual” to mean anything based on computers. A strong meaning of virtual reality, however, ties together these looser meanings. A certain kind of technology—“VR” for short—has become the model for a pervasive way of seeing things. Contemporary culture increasingly depends on information systems, so that we find virtual reality in the weak sense popping up everywhere, while virtual reality in the strong sense stands behind the scenes as a paradigm or special model for many things. The first step in virtual realism is to become clear about the meaning of virtual reality in the strong sense of the term. We need to be clear about using virtual reality as a model because the loose or weak sense of virtual reality grows increasingly fuzzy as the face value of the term wears down in the marketplace, where virtual reality sells automobiles and soap. Car manufacturers use virtual reality in television commercials: “Climb out of that virtual reality and test drive the real road car that stimulates all five senses!” Newspaper cartoons and entertainment parks pump the popularity of virtual reality. Products on CD-ROM bill their 3-D (three dimensional) graphics as “true virtual reality.” AT&T welcomes you into its “virtual world.” The term now belongs to the universal vocabulary. But movies and seasonal television shows should not stretch VR to a thin vapor. Because virtual reality belongs to an important part of the future, we need to understand it not only as an undercurrent affecting cultural developments but also as a powerful technology in its own right.
