Satellite Services For Disaster Management And Security Applications, Otto Koudelka, Peter Schrotter

Online Journal of Space Communication

Satellites can be a vital communications element in case of emergencies or natural disasters. This is not only true for developing countries, but also for highly developed regions. As the example of the floods in Central Europe in 2002 have shown, even basic telecommunications services can become unavailable. During natural or man-made disasters, access to data from meteorological and remote sensing satellites is extremely important for assessing the situation.

The Possible Use Of Telemedicine In Developing Countries, R. Wootton

Online Journal of Space Communication

Since the place of telemedicine in the industrialized world is by no means properly worked out yet, it might seem premature to consider its use in developing countries. Nonetheless, there is interest in the possible use of telemedicine in developing countries, from at least two organizations:

1. The Midjan group, an impromptu committee that was formed following the African Regional Telecommunications Development Conference in Abidjan in March 19963. This European telemedicine collaboration group aims to explore the use of telemedicine in developing countries. At present, the group includes representatives from 22 telecommunication and medical informatics suppliers, telecommunication operators, universities, hospitals and …

Usdla: An Instructional Media Selection Guide For Distance Learning, Jolly T. Holden, Philip Westfall

Online Journal of Space Communication

Purpose and Use of the Media Selection Guide

Increasingly, educators and trainers are challenged within their respective
organizations to provide for the efficient distribution of instructional con-
tent using instructional media. The appropriate selection of instructional
media to support distance learning is not intuitive and does not occur as a
matter of personal preference. On the contrary, instructional media selec-
tion is a systematic sequence of qualitative processes based on sound in-
structional design principles. Although media selection is often mentioned
when studying the discipline of instructional technology or Instructional
Systems Design (ISD), it is sometimes overlooked when applying the …

A Critical Perspective On The Indian Experience, K. P. Madhu

Online Journal of Space Communication

Growth in the use of satellites for education has been phenomenal in India. Beginning in the 1970s with the SITE project (Satellite Instructional Television Experiment) using a borrowed US satellite, then in the 1980s having its own indigenous INSAT satellite for educational TV, to having a full fledged educational channel on national TV in the 1990s, to the potential of 72 educational channels on EDUSAT at the beginning of the 21st century, shows long-term interest and commitment to this sector.

Distance Education Projects In Kyrgyzstan, Aida Aidakyeva

Online Journal of Space Communication

Kyrgyzstan is a landlocked country in Central Asia, one of the former Soviet Union republics, endowed with few natural resources, but it has a tremendously advantageous location on the major crossroads between Asia and Europe. Under the Soviet system the educational level of the population used to be very high in Kyrgyzstan. Recently the quality of education has started to worsen due to the continuous migration of the nation's specialists to more economically developed countries.

Distance Education Via Satellite: An Early Case Study Of The Indonesian Distance Education Satellite System, Willard D. Shaw

Online Journal of Space Communication

In 1980, the U.S. Agency for International Development initiated the AID Rural Satellite Program (RSP) to explore the potential of telecommunications as a means of extending scarce expert resources and expanding educational opportunities to remote and rural areas. Building on simple, interactive, and inexpensive telephone-based technologies, the Program developed teleconferencing systems for use as a development tool. Three pilot projects-in Indonesia, the West Indies, and Peru-were implemented to test and demonstrate that audioteleconferencing could reliably and affordably support development activities in education, health and agriculture.

Mexico's Educational Satellite Program

Satellite Technology Applications In Education: Examples From Greece, Yioryos Nardis

Online Journal of Space Communication

In ancient Greece, there was a mechanism for processing space information from the earth. The Antikythera has since been referred to as the world's first (mechanical) computer. In Greece, the Antikythera mechanism was used to fabricate calendars and schedules for seasons of harvesting and for organizing religious festivals. More than two millennia later, the descendants of these early scholars and technicians are still using outer space to educate themselves, but now the mechanism is electronic and digital using software and spaced-based satellites.

Worldspace Satellite Radio, S. Rangarajan

Online Journal of Space Communication

There are significant challenges to the delivery of quality education to less-developed nations. The primary obstacle is the lack of available and affordable connectivity solutions. Broadcast satellites can play an important role to fill this void. Particularly, digital broadcast satellites can provide audio and multimedia contents to multiple locations simultaneously. WorldSpace, with its extensive reach and low-cost terminals, offers a viable solution to increase the access to global educational resources. This solution includes audio formats, asynchronous multimedia delivery and creation of virtual classrooms with instructor-led, synchronous delivery of audio-visual presentations. These help enhance the quality of education delivery across Africa …

The Broadband Satellite System "Ipstar": Applications In Asia-Pacific Region, Masudul Biswas

Online Journal of Space Communication

The increasing trend of data traffic has turned the world into an information society. Even so, a significant portion of the areas and populations of the world have remained outside the flow of data traffic keeping them information-poor. That is why the issue of "digital divide" has popped up. But it is the cost-effectiveness factor of delivering systems that has guided the changes taking place in information and communication technologies that will ultimately benefit the end users.

Satellite-Based Distance Education In India, Sanjay Jasola, Ramesh Sharma

Ipstar And Education In Thailand, Taksin Uppalakom

Online Journal of Space Communication

The satellite communication project called IPSTAR was first developed in 1997 by Shin Satellite of Thailand. The project's aim was to deliver an inexpensive broadband satellite better suited to consumer markets. This project included a broadband satellite with more advanced ground system capabilities. The model for the IPSTAR ground system was first field deployed in the year 2000 using IPSTAR first generation services on conventional satellites. These first generation services are still available in various countries on Thaicom, INSAT, APSTAR and ST-1 satellites.

Access To Education In Africa Via Satellite, Hala Ibrahim

Online Journal of Space Communication

The potential of satellite technologies to improve access to education in Africa is discussed in this paper. Education contributes to sustainable development in Africa. However, accessibility to quality education has been stalled by many barriers, including lack of infrastructure, lack of trained teachers, high teacher/student ratios and shortage of educational materials. Satellites are among the information and communication technologies (ICTs) with the potential to by-pass terrestrial barriers to deliver educational services to scattered users.

The Challenges Of Distance Education, Abdul Waheed Khan

Online Journal of Space Communication

Education is of extreme importance as it is key to equipping the workforce with the skills needed to develop national economies. The importance is exemplified by the "Education for All" movement, a global commitment to provide quality basic education for all children, youth and adults, which links directly to the UN Millennium Development Goals (MDGs). Sustainable development of quality primary education is dependent on complementary development in the secondary and tertiary education sectors. With economies relying more and more on the generation and application of knowledge, productivity is increasingly dependent on the development and spread of technological innovation. Higher education …

Euler's Three-Body Problem, Sylvio R. Bistafa

Euleriana

In physics and astronomy, Euler's three-body problem is to solve for the motion of a body that is acted upon by the gravitational field of two other bodies. This problem is named after Leonhard Euler (1707-1783), who discussed it in memoirs published in the 1760s. In these publications, Euler found that the parameter that controls the relative distances among three collinear bodies is given by a quintic equation. Later on, in 1772, Lagrange dealt with the same problem, and demonstrated that for any three masses with circular orbits, there are two special constant-pattern solutions, one where the three bodies remain …

Gps & Galileo: Prospects For Building The Next Generation Of Global Navigation Satellite Systems, Glen Gibbons Jr.

Online Journal of Space Communication

In the next 5 to 10 years, the world will experience the emergence of a true Global Navigation Satellite System (GNSS) - a compatible and, in many respects, interoperable system of systems. The U.S. Global Positioning System, Europe's Galileo, perhaps Russia's Glonass system, and regional augmentations including the Wide Area Augmentation System (WAAS), the European Geostationary Navigation Overlay Service (EGNOS), radiobeacon-based systems such as the U.S. Nationwide Differential GPS, and compatible commercial differential correction services will comprise this multifaceted GNSS. Common signal structures and frequency plans will enable combined user equipment that reduces the technical complexity and cost, while vastly …

New U.S. Gps Policy From A European Perspective, Martin U. Ripple, Alexis Vidal

Online Journal of Space Communication

On December 8, 2004, the President of the United States of America authorized the new U.S. Space-based Positioning, Navigation and Timing Policy. This new policy sets forth a forward-looking framework for the management of GPS and its augmentations. In particular, the new U.S. policy mentions interaction with other satellite navigation systems.

Following the establishment of a U.S.-E.U. framework agreement for cooperation between GPS and Galileo, signed on June 26, 2004, European policy makers and industrialists expected clear statements on cooperation and interoperability issues from the new U.S. GPS policy. Regrettably, the related recommendations hold short of the need for cooperation …
