Balloon Experiments With Amateur Radio
Balloon Experiments with Amateur Radio (BEAR) is a series of Canadian-based amateur radio high-altitude balloon experiments by a group of amateur radio operators and experimenters from Sherwood Park and Edmonton, Alberta. The experiments started in the year 2000 and continued with BEAR-9 in 2012 reaching . The balloons are made of latex filled with either helium or hydrogen. All of the BEAR payloads carry a tracking system comprising a GPS receiver, an APRS encoder, and a radio transmitter module. Other experimental payload modules include an Amateur Radio crossband repeater, and a digital camera all of which is contained within an insulated foam box suspended below the balloon. A parachute recovery system is automatically deployed when the balloon bursts at altitude. BEAR-1 On May 27, 2000, this helium-filled balloon with a payload of 0.977 kg, was launched from the Bremner airport, and reached an altitude of 31,762 meters (104,206 feet). This first flight was a test ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces and ...

Daily Planet (TV Series)
''Daily Planet'' is a television program on Discovery Channel Canada which features daily news, discussion and commentary on the scientific aspects of current events and discoveries. The show first aired as ''@discovery.ca'' in 1995. It was renamed to ''Daily Planet'' in 2002. The show relaunched in high definition in 2011. From June 2012 until the show ended in May 2018, the hosts were Ziya Tong and Dan Riskin. ''Daily Planet'' aired on Discovery Channel Canada, Monday through Friday at 7 p.m. EST (Monday through Friday at 4 p.m. PST) as of September 4, 2012. The show was canceled by Bell Media on May 23, 2018 and its final episode aired on June 5, 2018. History ''Daily Planet'' first aired on January 1, 1995, the same day as the premiere of Discovery Channel Canada, under the name ''@discovery.ca'', it was an hour-long daily news magazine with a science news segment and several feature segments. During this era, the show aired for the fall/winter season. The summer s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weather Balloon
A weather balloon, also known as sounding balloon, is a balloon (specifically a type of high-altitude balloon) that carries instruments aloft to send back information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring device called a radiosonde. To obtain wind data, they can be tracked by radar, radio direction finding, or navigation systems (such as the satellite-based Global Positioning System, GPS). Balloons meant to stay at a constant altitude for long periods of time are known as ''transosondes''. Weather balloons that do not carry an instrument pack are used to determine upper-level winds and the height of cloud layers. For such balloons, a theodolite or total station is used to track the balloon's azimuth and elevation, which are then converted to estimated wind speed and direction and/or cloud height, as applicable. Weather balloons are launched around the world for observations used to diagnose current co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spirit Of Knoxville
The Spirit of Knoxville is a high-altitude balloon project run by amateur scientists and University of Tennessee students, with the ultimate goal of successfully sending an unmanned balloon across the Atlantic Ocean. The project is named for Charles Lindbergh's record-breaking ''Spirit of St. Louis'' aircraft. As of November 2008, five flights have been made, of which three were intended to cross the Atlantic, a goal which has yet to be achieved. History The project began in 2005, under the direction of students from the ''University of Tennessee Amateur Radio Club'', with a series of technology demonstrator flights dubbed the "Icarus" series. These flights tested small zero-pressure balloon designs, ballast dumping mechanisms and material, custom radio circuitry, the Distributed Tracking and Relay volunteer listening network, and command uplinking. The first Spirit of Knoxville "SNOX" designated flight was ''SNOX I'', reaching a stable float altitude of approximately o ...

Research Balloon
Research balloons are balloons that are used for scientific research. They are usually unmanned, filled with a lighter-than-air gas like helium, and fly at high altitudes. Meteorology, atmospheric research, astronomy, and military research may be conducted from a research balloon. Weather balloons are a type of research balloon. Research balloons usually study a single aspect of science, such as air pollution, air temperature, or wind currents, although sometimes several experiments or equipment are flown together. Other than weather balloons, few research balloons are launched every year. This is driven by the large cost of the balloon, the instrument, which is usually custom made, and the cost of the launch. Because of the altitude reached by most research balloons, the air is too thin and too cold for humans to survive, therefore most research balloons are unmanned and operated remotely. There have been some balloons equipped with pressurized cabins, beginning with pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kite Aerial Photography
Kite aerial photography (KAP) is a type of photography. A camera is lifted using a kite and is triggered either remotely or automatically to take aerial photographs. The camera rigs can range from the extremely simple, consisting of a trigger mechanism with a disposable camera, to complex apparatus using radio control and digital cameras. On some occasions it can be a good alternative to other forms of aerial photography. Camera rig and stabilisation The camera can be attached directly to the kite but is usually secured to an adjustable rig suspended from the kite line at a distance from the kite. This distance reduces excessive movement being transmitted from the kite to the camera and allows the kite to be flown into higher, stable air before the camera is attached. If possible, the camera is set to a high shutter speed to reduce motion blur. Cameras using internal image stabilization features can increase the number of sharp photos. In order to take photographs that are orie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-altitude Balloon
High-altitude balloons are crewed or uncrewed balloons, usually filled with helium or hydrogen, that are released into the stratosphere, generally attaining between above sea level. In 2002, a balloon named BU60-1 reached a record altitude of . The most common type of high-altitude balloons is weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. These balloons are launched into what is termed " near space", defined as the area of Earth's atmosphere between the Armstrong limit ( above sea level), where pressure falls to the point that a human being cannot survive without a pressurised suit, and the Kármán line ( above sea level), where astrodynamics must take over from aerodynamics in order to maintain flight. Due to the low cost of GPS and communications equipment, high-altitude bal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
