Online Journal of Space Communication

In order to better support its overriding objective of the Canadian Space Program, which is "to develop and apply space science and technology in order to meet Canadian needs and develop an internationally competitive space industry," the CSA has created a grants and contributions program to support awareness, research and training in space science and technology.

Since its creation in 1989, the Canadian Space Agency (CSA) has set out to ensure that all Canadians learn and benefit from the innovations of space science and technology to the greatest extent possible. Its objectives are to support and promote a highly competitive space industry and address the needs of Canadian society. With almost half of Canada's GDP growth in the knowledge-intensive sectors of the economy, the Canadian Space Program is a key driver behind continued leadership on the world stage, new opportunities for industry and scientists, and long-term social and economic benefits for all Canadians.

Historical Development: Msat Program, Jack Rigley

Online Journal of Space Communication

As early as 1967, Canadian researchers had been involved in trials with the U.S. on the use of UHF satellites for mobile services primarily for defence operations. The use of UHF frequencies, with satellites such as LES-5, LES-6 and TACSAT offered the possibility of small lightweight mobile or transportable terminals, and several demonstrations were carried out in the land, maritime, and aeronautical environment. The world's first direct aircraft-to-aircraft voice communications via satellite was carried out May16, 1970 between two Canadian DND aircraft.

Historical Development: Hermes Satellite, Jack Rigley

Online Journal of Space Communication

In the early 1960's, international communication satellites using the 6/4 GHz bands and positioned in the geostationary satellite orbit were found to be capable of providing high quality telecommunications services. Domestic satellite communications systems were planned and were implemented, beginning in 1972, with the Telesat Canada ANIK-A System.

Because of the success of the Hermes program and under an arrangement between Telesat Canada and the federal government, the next satellite commissioned by Telesat-Anik B-was equipped with 4 experimental 14/12 GHz transponders in addition to 12 commercial radio frequency channels in the 6/4 GHz band used by the earlier Anik A satellites. Spacecraft construction was awarded to RCA Astro-Electronics Division.

The Department of Communications of the Federal Government ran a competition across Canada to name Telesat's first series of satellites. In November 1969, the winner of the contest was announced. A St. Leonard, Quebec, supermarket employee, Mary Frances Czapla suggested ANIK which means "brother" in the language of the Inuit. It was selected as the winning entry by a panel of judges which included Marshall McLuhan.

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.

Managing Protein In Spring Wheat With Aerial And Satellite Imagery, Dennis L. Wright Jr., Glen Ritchie, V. Philip Rasmussen, R. Douglas Ramsey, Doran Baker

Online Journal of Space Communication

Nitrogen fertilizer application can help wheat growers increase crop value and marketability by increasing grain quality. Nitrogen (N) is often applied at heading as a method of increasing protein content and therefore quality of wheat. Our objectives were to obtain spectral signatures of wheat under various N rates (0, 72, 180, 234 kg N ha-1), test various spectral methods of identifying crop stress, and observe the grain protein response to a midseason N application. Spectral data from satellite and aerial platforms were compared to preseason N treatments and flag-leaf tissue samples. Spectral data correlated well with preseason and flag leaf …

A Gis/Gps Approach For The Abondoned Mine Inventory Of The Monongahela National Forest Using Space Borne And Aerial Images For Basemap Selection, John R. Ferguson Ii, James O. Brumfield, Joseph Langdon

Online Journal of Space Communication

The Monongahela National Forest spans 10 counties in eastern central West Virginia. It has been an area of high mining and timbering activities throughout much of the early to mid twentieth century. As a result, the United States Forest Service (USFS) has focused reclamation and remediation efforts on the abandoned mine land areas. Much of the area has been subjected to mining after effects such as acid mine drainage, structural remains, gob/spoil piles, garbage piles, mine portals, and highwalls. In 1998 the USFS contracted with the U.S. Army Corps of Engineers (USACE) to provide a detailed georeferenced inventory with a …
