European Fireball Network
European Fireball Network is an international organization based in Central Europe (Germany and Czech Republic). Its purpose is systematic and simultaneous night observation of meteors and other nebular objects. Description The network was initially located at the Ondřejov Observatory, Czech Republic, after the fall of the Příbram meteorite on 7 April 1959, which was the first meteorite simultaneously observed by several stations. By 1963, the network consisted of five stations. It was later (about 1968) expanded by the installation of about 15 new stations in Germany and named the European Fireball Network. The network currently consists of at least 34 camera stations located in Germany, Czech Republic, Belgium, Luxembourg, Switzerland, Slovakia and Austria at elevations up to 1846 m above mean sea level. The cameras are separated by a distance of about ; they cover an area of about and photograph the entire visible sky. Cameras at Czech stations are equipped with fisheye ...

Slovakia
Slovakia (; sk, Slovensko ), officially the Slovak Republic ( sk, Slovenská republika, links=no ), is a landlocked country in Central Europe. It is bordered by Poland to the north, Ukraine to the east, Hungary to the south, Austria to the southwest, and the Czech Republic to the northwest. Slovakia's mostly mountainous territory spans about , with a population of over 5.4 million. The capital and largest city is Bratislava, while the second largest city is Košice. The Slavs arrived in the territory of present-day Slovakia in the fifth and sixth centuries. In the seventh century, they played a significant role in the creation of Samo's Empire. In the ninth century, they established the Principality of Nitra, which was later conquered by the Principality of Moravia to establish Great Moravia. In the 10th century, after the dissolution of Great Moravia, the territory was integrated into the Principality of Hungary, which then became the Kingdom of Hungary in 1000. In 1241 a ...

Neuschwanstein (meteorite)
Neuschwanstein was an enstatite chondrite (type EL6) meteorite that fell to Earth on 6 April 2002 at 22:20:18 GMT near Neuschwanstein Castle, Bavaria, at the Germany–Austria border. The original meteorite burst into several fragments at a height of about 22 kilometers (14 miles) above the ground. The fragments descended on an area of several square kilometers. Three fragments were recovered with a total mass of about . Neuschwanstein was the first meteorite in Germany, and the fourth in the world, that was monitored by one of the world's fireball networks, namely by the European Fireball Network. Photographing the meteor simultaneously from several locations allowed accurate reconstruction of its trajectory. Meteorite fall The trace of the Neuschwanstein meteor within the Earth's atmosphere began at a height of about , about east-northeast of Innsbruck, with an entry angle of about 49° to the horizontal, and ended above the Earth's surface. Shortly before that it split ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Triangulation
In trigonometry and geometry, triangulation is the process of determining the location of a point by forming triangles to the point from known points. Applications In surveying Specifically in surveying, triangulation involves only angle measurements at known points, rather than measuring distances to the point directly as in trilateration; the use of both angles and distance measurements is referred to as triangulateration. In computer vision Computer stereo vision and optical 3D measuring systems use this principle to determine the spatial dimensions and the geometry of an item. Basically, the configuration consists of two sensors observing the item. One of the sensors is typically a digital camera device, and the other one can also be a camera or a light projector. The projection centers of the sensors and the considered point on the object's surface define a (spatial) triangle. Within this triangle, the distance between the sensors is the base ''b'' and must be known. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zenith
The zenith (, ) is an imaginary point directly "above" a particular location, on the celestial sphere. "Above" means in the vertical direction (plumb line) opposite to the gravity direction at that location (nadir). The zenith is the "highest" point on the celestial sphere. Origin The word "zenith" derives from an inaccurate reading of the Arabic expression (), meaning "direction of the head" or "path above the head", by Medieval Latin scribes in the Middle Ages (during the 14th century), possibly through Old Spanish. It was reduced to "samt" ("direction") and miswritten as "senit"/"cenit", the "m" being misread as "ni". Through the Old French "cenith", "zenith" first appeared in the 17th century. Relevance and use The term ''zenith'' sometimes means the highest point, way, or level reached by a celestial body on its daily apparent path around a given point of observation. This sense of the word is often used to describe the position of the Sun ("The sun reached its zenit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
