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.

Cultivating Creativity In Aerospace Systems Engineering To Manage Complexity, Kenneth Lucas Dodd

Master's Theses

In recent decades, complexity in aerospace programs has been increasing, leading to large budget and schedule overruns. Many of the risks of complex system development can be attributed to the inadequacy of linear methods when applied to nonlinear domains, i.e., oversimplification in a program amplifies the amount of risk produced when a system behaves unexpectedly. Effectively managing complexity involves responding to the various sources of complexity, whether it appears in the objective behavior of the system itself or in the subjective behavior of the people developing it. Thus, the engineering of complex systems requires nonlinear modeling methods of the system …

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, …

Development Of A Cubesat Conceptual Design Tool And Implementation Of The Eps Design Module, Sean K. Nogrady

Master's Theses

This thesis is the product of an effort to develop a CubeSat Conceptual Design Tool for the California Polytechnic State University CubeSat Laboratory. Such a tool is necessary due to inefficiencies with the current conceptual design process. It is being developed to increase accessibility, reduce design time, and promote good systems engineering within CubeSat development.

The development of the architecture of a conceptual design tool, the core user-interface element, and the completion of a module for the electrical power subsystem is the focus of this thesis. The architecture is built around different modules to design different subsystems that work in …

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.

Satcom Today In Canada: Significant Research: Overview Of The Cospas-Sarsat Satellite System For Search And Rescue, J. V. King

Online Journal of Space Communication

Cospas-Sarsat, an international satellite system for search and rescue, started operating in 1982 and has been credited with saving thousands of lives since then. Hundreds of thousands of aviators, mariners and land users worldwide are equipped with Cospas-Sarsat distress beacons, which could help save their lives in emergency situations anywhere in the world. This paper outlines the evolution of the system and describes how satellites are constantly circling the globe monitoring for ‘SOS signals’, while tracking stations on six continents receive the satellite signals, compute the locations of the distress events and forward the calls for help to the appropriate …
