Current Development: How One Faith-Based Organization Uses Satellite Technology To Bridge The Digital Divide, Jeffrey B. Roberts

Online Journal of Space Communication

From its founding in 1830, the Church of Jesus Christ of Latter-day Saints has endeavored to fulfill the divine command to "Go ye into all the world, and preach the gospel to every creature." Proclaiming the gospel of Jesus Christ throughout the world remains a daunting challenge even in modern times. How does a religious organization preach its doctrine to people of all nations, race, cultures, etc? How does it support its growing membership and provide the necessary training for new members and new leaders? How does it assure that its teachings remain consistent around the world? How does it …

Current Development: The Digital Divide - An Appalachian Ohio Perspective, John C. Hoag

Online Journal of Space Communication

The objective of this paper is to assess the role of satellite communication with respect to the Digital Divide in the United States. A secondary objective is to review the capabilities, capacity, and availability of current solutions in light of potential applications in other markets and situations.

This paper contains a review of the Digital Divide in general with additional attention to local Ohio developments and the use of satellite broadband Internet service. We then discuss different satellite-based solutions for residential and commercial Internet access.

Current Development: Learning Without Boundary: Application Of Satellite Communication System On Distance Education, Hsin-Ho Tsao

Online Journal of Space Communication

Nowadays, the concept of global village has been developed over the world due to the development of communication technology. The information boundaries between areas and regions are gradually eliminated. People are able to have long-distance communication and information exchange, such as searching information via the Internet and making long distance calls that include images. The convenience of communication brought by the technology is applied to education as well.

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.

3-Axis Reaction Wheel System For Cubesats, Alexandra Mae Lee, Daniel Leon, Christopher Pablo Casillas, Rose Mccarver

Mechanical Engineering

Reaction wheels are a common, but expensive, component used in CubeSats, that can accurately position a satellite using an imparted momentum (or impulse) from a rotating flywheel to adjust a satellite’s attitude. This document serves as the final design review and report for the 3-Axis Reaction Wheel Senior Design Project in the Mechanical Engineering Department of California Polytechnic State University, San Luis Obispo. The goal of this project is to produce a functional, low-cost 3-axis reaction wheel system based on previous research done by a master’s student at Cal Poly to be implemented in future CubeSats in the Cal Poly …

Simulation Of A Configurable Hybrid Aircraft, Brandon Bartlett

Master's Theses

As the demand for air transportation is projected to increase, the environmental impacts produced by air travel will also increase. In order to counter the environmental impacts while also meeting the demand for air travel, there are goals and research initiatives that aim to develop more efficient aircraft. An emerging technology that supports these goals is the application of hybrid propulsion to aircraft, but there is a challenge in effectively exploring the performance of hybrid aircraft due to the time and money required for safe flight testing and due to the diverse design space of hybrid architectures and components. Therefore, …

Passive Disposal Of Launch Vehicle Stages In Geostationary Transfer Orbits Leveraging Small Satellite Technologies, Marc Alexander Galles

Master's Theses

Once a satellite has completed its operational period, it must be removed responsibly in order to reduce the risk of impacting other missions. Geostationary Transfer Orbits (GTOs) offer unique challenges when considering disposal of spacecraft, as high eccentricity and orbital energy give rise to unique challenges for spacecraft designers. By leveraging small satellite research and integration techniques, a deployable drag sail module was analyzed that can shorten the expected orbit time of launch vehicle stages in GTO. A tool was developed to efficiently model spacecraft trajectories over long periods of time, which allowed for analysis of an object’s expected lifetime …

The Role Of Partnerships Government/Industry/International, W.M. (Mac) Evans

Online Journal of Space Communication

Much of Canada's involvement in space activities, particularly in the earlier years, related to its interest in satellite communications as a means to provide equitable access by all Canadians to telecommunications services. It also provided the impetus for Canada signing a cooperative agreement with ESA. There are a number of firsts in satellite communications to which Canada can lay claim. However the environment for space communications systems and services has changed dramatically and continues to change due to factors such as global deregulation, rapid advance of telecommunications technology, industrial consolidation and intense competition.

Market Analysis, W.M. (Mac) Evans

Online Journal of Space Communication

Canadian space companies have developed impressive and globally competitive competencies in some niche areas of satellite communications. This has allowed them to be very successful in domestic and export markets. In fact, 63% of total 2000 revenues of $1.4 billion were from Telecommunications. Satellite communications can be considered the cornerstone of the Canadian space industry at large.

Industry Capabilities And Services, W.M. (Mac) Evans

Online Journal of Space Communication

Space Communication technologies have provided the world with satellite communications and global satellite navigation infrastructures that have become strategic assets for the economic, political, and military sectors of countries around the world. Their omnipresence in our everyday lives and their significant role in world commerce, security and humanitarian operations such as Search and Rescue have made telecommunications and global navigation satellites indispensable.

The Future Of Satcom In Canada: R & D Labs, Paul Bush

Online Journal of Space Communication

Recognizing the need to evaluate and test emerging technologies and applications, Telesat has recently made a significant additional investment to its existing R&D lab. The upgraded facility is a 4000 square-foot area dedicated to satellite-based broadband trials and demonstrations. The R&D Lab hosts active computing platforms that are networked over satellite and linked by a common theme of connecting Canada and Canadians. On-going trials are managed from a hub area and a network control centre within the Lab. The lab is designed to provide both a development environment and an educational and demonstration area.

The Future Of Satcom In Canada: New Technologies Needed, Virendra Jha

Online Journal of Space Communication

The Government of Canada has a clear goal of making Canada the most connected country in the world. The vast geographic topology and wide population distribution - some in remote communities - raise distinct technical and economic challenges in achieving this goal. In addition, communications are already used in virtually all space projects - either for the command of the Spacecraft, or as the raison d'être of the mission. Undoubtedly, to support the very nature of space projects and to achieve the goal of connecting all Canadians, ever-improved technologies are being sought.
