As a result of new developments in broadband communication, residential users, office workers and those who move from place to place have more ways to access the programming and services they want when they want them.

Bridging The Digital Divide: Towards A New Paradigm, Virgil Labrador

Online Journal of Space Communication

My direct experience in the "digital divide" was when I was marketing director for a band-new state-of-the-art program origination and satellite transmission facility in Singapore seven years ago in 1996. Our first and anchor client was the highly successful Discovery Network--which housed in our facility the first all-digital channel to the Asia-Pacific market.

Strengthening Access To Communications Policy & Regulatory Guidelines For Satellite Services, David Hartshorn

Online Journal of Space Communication

This work is designed to help bridge the "Regulatory Divide" that continues to thwart end users' efforts to obtain affordable communications. From tele-medicine to distance learning to rural telecenters to disaster recovery to enterprise networks, the satellite industry is offering not only telecommunications solutions for the "have nots", but also the regulatory tools to enable the public sector to fulfill their policy objectives.

Technological Issues: A Day In The Life Of A Satcom Engineer In Nigeria, Andy Hope

Online Journal of Space Communication

The day began early, like all African days.

Social And Cultural Issues: The Impact Of Digital Divide On Development And How Satellite Addresses This Problem, Robin Gambu Wani Latio

Online Journal of Space Communication

The paper examines the problem of inaccessibility to education by the vast majority in East Africa, the factors that contribute to education problems and how the digital divide further helps isolate people in the rural communities of the region.

The author proposes satellite technology as the solution to the digital divide and offers reasons to support this proposition. Technology use in Uganda is discussed as a case study to provide further evidence that satellite communications help close the digital divide gap.

Social And Cultural Issues: Social, Cultural And Economic Issues In The Digital Divide - Literature Review And Case Study Of Japan, Shuho Otani

Online Journal of Space Communication

The definition of the digital divide generally refers to unequal access to digital and network resources, including the Internet, and opportunities to learn using information and communication technologies. The gaps are usually concerned with economic, social and cultural issues, such as income, age, education, gender, ethnic background, and physical handicaps.

Issue 5: From The Guest Editor, Bruce Elbert

Online Journal of Space Communication

This issue of the Online Journal of Space Communication focuses on a matter of social concern for which satellite technology is well-positioned to help overcome traditional communication limitations of terrain and distance. Literally the entire globe is within the reach of one satellite system or another, making it possible to extend telephone, television, radio, data and Internet communications to every corner and everybody.

Historical Development: The Alouette Program, Jack Rigley

Online Journal of Space Communication

In the 1950's at the height of the Cold War, Defence Research Bureau (DRB) laboratories, located in Ottawa, were involved in research and development to keep Canadians abreast of leading edge technology and ensure that Canadian forces were adequately equipped for their defence role.

Astronaut-Acquired Photography Of Earth: Its History And Continued Applicability In Quantitative Analyses, Jennifer Gebelein

Online Journal of Space Communication

Aerial and satellite photography has been used extensively in many different research efforts, for example, atmospheric studies, vegetation analysis, and change detection. Archives of historical aerial and satellite photography are a valuable resource to the science community.

There is currently an archive of over 450,000 photographs of Earth taken by United States astronauts dating back to the early 1960's. This archive covers the majority of the Earth's surface and offers imagery taken by a variety of camera configurations including film and digital, various lenses, different look angles, and changing solar illuminance. There is extensive repeat coverage over many regions of …

Multi-Sensor Image Registration, Fusion And Dimension Reduction, Jacqueline Le Moigne

Online Journal of Space Communication

With the development of future spacecraft formations comes a number of complex challenges such as maintaining precise relative position and specified attitudes, as well as being able to communicate with each other. More generally, with the advent of spacecraft formations, issues related to performing on-board and automatic data computing and analysis as well as decision planning and scheduling will figure among the most important requirements. Among those, automatic image registration, image fusion and dimension reduction represent intelligent technologies that would reduce mission costs,would enable autonomous decisions to be taken on-board, and would make formation flying adaptive, self-reliant, and cooperative. For …

Ohioview: A Case Study In Progress, James K. Lein

Online Journal of Space Communication

OhioView is a consortium of 10 state universities within Ohio established to promote the low-cost distribution of US Government civilian satellite data for public use. Dedicated to the goal of reducing the financial and technological barriers to use remotely sensed satellite data, OhioView has made a significant contributions to the educational, research and public use of satellite imagery through a continuing program of focused and applied land cover studies, expanded university level teaching, and public and private outreach and training. A grassroots organization formed in 1996 by its member universities, OhioView's mission is to develop remote sensing applications, create educational …
