Provinces And Territories Of Canada
Canada has ten provinces and three territories that are sub-national administrative divisions under the jurisdiction of the Constitution of Canada, Canadian Constitution. In the 1867 Canadian Confederation, three provinces of British North America—New Brunswick, Nova Scotia, and the Province of Canada (which upon Confederation was divided into Ontario and Quebec)—united to form a federation, becoming a fully Independence, independent country over the next century. Over its history, Canada's international borders have changed several times as it has added territories and provinces, making it the List of countries and dependencies by area, world's second-largest country by area. The major difference between a Canadian province and a territory is that provinces receive their power and authority from the ''Constitution Act, 1867'' (formerly called the ''British North America Acts, British North America Act, 1867''), whereas territories are federal territories whose governments a ...

Polar Environment Atmospheric Research Laboratory
The Polar Environment Atmospheric Research Laboratory (PEARL) is an atmospheric research facility in the Canadian High Arctic, located on Ellesmere Island, Nunavut. Considered one of the most important Arctic research labs in the world, it was the subject of international media attention when it almost closed due to funding cuts by the Canadian Federal Government in 2012. History PEARL is located on Ellesmere Island, about 15 km from the Eureka Weather Station in Eureka, Nunavut and about 1,100 km from the North Pole. It consists of 3 facilities: the Ridge Lab building, originally built by the Meteorological Service of Canada in 1992 to hold the Arctic Stratospheric Ozone Observatory (AStrO), the Zero (0) Altitude PEARL Auxiliary Laboratory (0PAL) and the Surface Atmospheric Flux and IRradiation Extension (SAFIRE). Full time AStrO operations ended in 2001 due to government budget cuts. After hearing that the Ridge Lab was in danger of being demolished, Canadian Netw ...

Geosynchronous Orbit
A geosynchronous orbit (sometimes abbreviated GSO) is an Earth-centered orbit with an orbital period that matches Earth's rotation on its axis, 23 hours, 56 minutes, and 4 seconds (one sidereal day). The synchronization of rotation and orbital period means that, for an observer on Earth's surface, an object in geosynchronous orbit returns to exactly the same position in the sky after a period of one sidereal day. Over the course of a day, the object's position in the sky may remain still or trace out a path, typically in a figure-8 form, whose precise characteristics depend on the orbit's inclination and eccentricity. A circular geosynchronous orbit has a constant altitude of . A special case of geosynchronous orbit is the geostationary orbit (often abbreviated ''GEO''), which is a circular geosynchronous orbit in Earth's equatorial plane with both inclination and eccentricity equal to 0. A satellite in a geostationary orbit remains in the same position in the sky to observers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CFS Alert
Canadian Forces Station Alert (), often shortened to CFS Alert (), is a signals intelligence intercept facility of the Canadian Armed Forces at Alert, in the Qikiqtaaluk Region of Nunavut, Canada. Located on the northeastern tip of Ellesmere Island, Alert is the northernmost continuously inhabited place in the world. It takes its name from HMS ''Alert'', which wintered east of the present station off what is now Cape Sheridan, Nunavut in 1875–1876. History Alert Wireless Station Alert, then in Canada's Northwest Territories, was first settled April 9, 1950, when the first staff for the Joint Arctic Weather Station (JAWS) arrived and began construction. Since the beginning of the JAWS project, the Canadian military had been interested in the establishment at Alert for several reasons: the JAWS facility extended Canadian sovereignty over a large uninhabited area which Canada claimed as its sovereign territory, and furthermore, its proximity to the Soviet Union made it o ...

Operation Hurricane (Canada)
Operation Hurricane is an annual month-long technical maintenance mission conducted by Canadian Forces personnel in the Canadian Arctic. Each summer, since 1982, Canadian military technicians and support personnel have been deployed by helicopters to repair and resupply the otherwise unattendeHigh Arctic Data Communications System(HADCS), between CFS Alert and Eureka, Nunavut, Eureka, located on Ellesmere Island in Nunavut. In 2005, military personnel also conducted a patrol, during which they raised a Flag of Canada, Canadian flag on Hans Island – a small, barren island in the Nares Strait, between northern Ellesmere Island and Greenland. Denmark disputed Canada's claim to this territory until 2022 when the countries agreed to split the island between both nations, ending a 17 year negotiation process.

Antenna (radio)
In radio-frequency engineering, an antenna (American English) or aerial (British English) is an electronic device that converts an alternating current, alternating electric current into radio waves (transmitting), or radio waves into an electric current (receiving). It is the interface between radio waves Radio propagation, propagating through space and electric currents moving in metal Electrical conductor, conductors, used with a transmitter or receiver (radio), receiver. In transmission (telecommunications), transmission, a radio transmitter supplies an electric current to the antenna's Terminal (electronics), terminals, and the antenna radiates the energy from the current as electromagnetic radiation, electromagnetic waves (radio waves). In receiver (radio), reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be amplifier, amplified. Antennas are essential components ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a Transponder (satellite communications), transponder; it creates a communication channel between a source transmitter and a Radio receiver, receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The radio waves used for telecommunications links travel by Line-of-sight propagation, line of sight and so are obstructe ...

Search And Rescue
Search and rescue (SAR) is the search for and provision of aid to people who are in distress or imminent danger. The general field of search and rescue includes many specialty sub-fields, typically determined by the type of terrain the search is conducted over. These include mountain rescue; ground search and rescue, including the use of search and rescue dogs (such as K9 units); urban search and rescue in cities; combat search and rescue on the battlefield and air-sea rescue over water. International Search and Rescue Advisory Group (INSARAG) is a UN organisation that promotes the exchange of information between national urban search and rescue organisations. The duty to render assistance is covered by Article 98 of the UNCLOS. Definitions There are many different definitions of search and rescue, depending on the agency involved and country in question. *Canadian Armed Forces and Canadian Coast Guard: "Search and Rescue comprises the search for, and provision of ai ...

Canadian American Strategic Review
The Canadian American Strategic Review was an influential Canadian think-tank that comments on Canadian Defence and sovereignty issues. The think-tank operated, for many years, from the campus of Simon Fraser University. It shut down in 2016. History In 2007 the '' Canwest News Services'' cited one of the think-tank's papers on the option of employing Canadian Forces smaller CH-146 Griffon helicopters to Afghanistan. In 2008 the US Naval War College's '' International Law Studies'' cited one of the think-tank's papers on Canadian Prime Minister Stephen Harper's 2005 change in Defence policy. In 2009 Peter Worthington cited one of the review's papers that statistically analyzed the safety of the vehicles the Canadian Forces used in Afghanistan. In 2016, Steven Chase repeatedly quoted the Review's Stephen Priestley when ''The Globe and Mail'' reported on how Saudi Arabia used Canadian made light armored vehicles in ways that violated their export license.

Bombardier Challenger 600 Series
The Bombardier Challenger 600 series is a family of business jets developed by Canadair after a Bill Lear concept, and then produced from 1986 by its new owner, Bombardier Aerospace. At the end of 1975, Canadair began funding the development of LearStar 600, and then bought the design for a wide-cabin business jet in April 1976. On 29 October, the programme was launched, backed by the Canadian federal government, and designed to comply with new Federal Aviation Regulations#Part 25, FAR part 25 standards. In March 1977, it was renamed the Challenger 600 after Bill Lear was phased out, and the original conventional tail was changed for a T-tail among other developments. The first prototype was rolled out on 25 May 1978, and performed its maiden flight on 8 November. The flight test program saw a deadly crash on 3 April 1980, but Department of Transport (Canada), Transport Canada approved the CL-600 type certification on 10 August 1980. In 1986, Canadair was close to bankruptcy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
