The broadcast ranges from observatories in Europe to observatories in Australia, and from an observatory orbiting in space to one sunk a mile underground at the bottom of a gold mine in the South Dakota Badlands. Some 30 distinguished astronomers are seen at work in their observatories. Among them are Sir Bernard Lovell at Jodrell Bank, England; Thomas Gold at the giant Arecibo radiotelescope, high in the hills of Puerto Rico; Bernard Mills hunting pulsars at Mount Stromlo in Australia; Jan Cort at Dwingeloo in Holland; Maarten Schmidt at Palomar; Sir Martin Ryle at Cambridge, England; Tom Kinman at Lick, California; Frank Low in his Lear Jet “observatory” flying his telescope above cloud cover; and Donald Kniffen sending up a gamma-ray tracking chamber in a balloon. The birth and death of stars, the possibilities of hitherto unknown sources of energy out in the stars, and quasars that act in ways nothing known in physics can explain, are examined by Robert Dicke of Princeton, Jesse Greenstein of Palomar and Mount Wilson, Allan Sandage and Bernard Pagel of the Royal Greenwich Observatory, physicist Philip Morrison of M.I.T., and Richard Henry’, rocket researcher at the United States Naval Research Laboratory. Did the universe begin in a week’s time, with one explosion, as proponents of the “Big Bang” theory argue, or is it continually expanding in a relatively orderly way through all time, as defenders of the “Steady State” theory maintain? The controversy, which has implications for theology as well as for the movement of man out into space, is described in the broadcast. The broadcast goes to Japan to visit the home of Tsutomu Seki, the amateur astronomer who teaches classical guitar for a livelihood and who in 1965, with Kaoru Keya, discovered the Ikeya- Seki comet. Featured in the broadcast is a studio reconstruction of a section of the universe, with 100 stars hung in their proper perspective in space. The astronomical proportions involved in the scale replica are so vast that one foot of studio floor equals three light years—or 18,000,000,000,000 (18 trillion) —miles. The script of “The Violent Universe” was written by Nigel Calder. Narrator is Carl Sagan, professor of astronomy at Cornell, with Robert MacNeil, PBL special correspondent in London who is also a reporter for the BBC. This 5-part series from archive.org has been restored for your viewing pleasure by SciWorx. You are welcome! The Orbiting Astronomical Observatory (OAO) satellites were a series of four American space observatories launched by NASA between 1966 and 1972, managed by NASA Chief of Astronomy Nancy Grace Roman. These observatories, including the first successful space telescope, provided the first high-quality observations of many objects in ultraviolet light. Although two OAO missions were failures, the success of the other two increased awareness within the astronomical community of the benefits of space-based observations, and led to the instigation of the Hubble Space Telescope.

If you ever wanted to take the first steps to make your own hydrogen at home, here is how you start. A Hoffman Apparatus is a piece of glass lab equipment that is great for electrolysis experiments, mostly used to generate hydrogen and oxygen from water. It is a really useful addition to your home lab. A Hoffman Apparatus is an apparatus for electrolyzing water, invented by August Wilhelm von Hofmann (1818–1892) in 1866. It consists of three joined upright cylinders, usually glass. The inner cylinder is open at the top to allow addition of water and an ionic compound to improve conductivity, such as a small amount of sulfuric acid. A platinum electrode is placed inside the bottom of each of the two side cylinders, connected to the positive and negative terminals of a source of electricity. When current is run through Hoffmann's apparatus, gaseous oxygen forms at the anode and gaseous hydrogen at the cathode. Each gas displaces water and collects at the top of the two outer tubes.

Hofmann voltameters are no longer used as electrical measuring devices. However, before the invention of the ammeter, voltameters were often used to measure direct current, since current through a voltameter with iron or copper electrodes electroplates the cathode with an amount of metal from the anode directly proportional to the total coulombs of charge transferred (Faraday's law of electrolysis). The modern name is "electrochemical coulometer" or more popularly called a "Hoffman Apparatus." Although the correct spelling of Hofmann contains only one 'f' and two "n", it is often incorrectly depicted as Hoffman.

The Cybertruck was unveiled at the Tesla Design Studio in Los Angeles on 21 November 2019. During the unveiling, Tesla claimed that the Cybertruck's "Armor Glass" windows were virtually unbreakable, but two windows shattered when Franz von Holzhausen threw a metal ball at them. Musk jokingly exclaimed that "the ball didn't make it through" and "we'll fix it in post". He later explained that the windows were damaged because in an earlier demonstration, the door was hit by a sledgehammer and that cracked the base of the glass. The fact that the rear windows shattered too was explained by microscopic cracks developed in both windows during previous ball throwing tests before the unveiling. At the end of the presentation, the Tesla Cyberquad, an all-terrain vehicle (ATV), was driven onto the bed of the Cybertruck using built-in ramps in the tailgate. The Cyberquad was plugged into the Cybertruck's onboard power outlet to charge the Cyberquad's batteries. The ATV will be available for sale as an optional package with the Cybertruck This is an archival video of that unveiling event. #Tesla #Cybertruck #EV Thanks to all my Patreon supporters!

According to Musk, the design of the Cybertruck was inspired by Blade Runner and the Lotus Esprit driven by James Bond in The Spy Who Loved Me, which doubled as a submarine. The Cybertruck uses unibody construction (termed an "exoskeleton" by Tesla) like most passenger cars, rather than the body-on-frame construction which is typical of trucks, as a standard vehicle frame would conflict with the under-floor battery pack. It uses unusually thick 3 mm (1⁄8 in) 30x-series cold-rolled stainless steel body panels, which cannot be stamped like conventional automobile parts. The panels can only be bent along straight lines, resulting in a very distinctive faceted design which has been called "low-poly" or likened to origami. This material is the same material SpaceX (also owned by Musk) uses on their Starship Rocket, because it distributes stress more evenly and allows for more interior volume. Earlier design concepts for Cybertruck had included using titanium for the outer panels, but this was later switched to stainless steel for additional strength, using an alloy that was developed in-house by Tesla. The Cybertruck unveiling event was covered heavily by traditional media and online blogs/social media. In social media, many commentators expressed dislike of the sharp contours and unusual exterior of the Cybertruck. Tesla, Inc. stock was down 6% following the Cybertruck announcement. On 23 November 2019, Elon Musk tweeted that Tesla had received 146,000 pre-orders in the first 1.5 days after the unveiling—each requiring a US$100 refundable deposit—with 42% choosing the dual-motor configuration, 41% choosing the tri-motor configuration, and 17% choosing the single-motor configuration. The number reached 250,000 on 26 November. Additionally, a video of the Cybertruck pulling a rear-wheel-drive Ford F-150 uphill in a tug of war resulted in 14,000 comments and 619,000 likes on Twitter. Various news outlets pointed out this was not a result of superior horsepower or torque, but simply due to the Cybertruck being heavier. In January 2020, Automobile Magazine named Cybertruck the "Concept Car of the Year" for 2019.

Such images may or may not be considered pictograms in the general sense. A pictograph is a pictorial symbol for a word or phrase. Pictographs were used as the earliest known form of writing, examples having been discovered in Egypt and Mesopotamia from before 3000 BC. Early written symbols were based on pictographs (pictures which resemble what they signify) and ideograms (symbols which represent ideas). Ancient Sumerian, Egyptian, and Chinese civilizations began to adapt such symbols to represent concepts, developing them into logographic writing systems. Pictographs are still in use as the main medium of written communication in some non-literate cultures in Africa, the Americas, and Oceania. Pictographs are often used as simple, pictorial, representational symbols by most contemporary cultures. Pictographs can be considered an art form, or can be considered a written language and are designated as such in Pre-Columbian art, Native American art, Ancient Mesopotamia and Painting in the Americas before Colonization. One example of many is the Rock art of the Chumash people, part of the Native American history of California. Some scientists in the field of neuropsychiatry and neuropsychology, such as Mario Christian Meyer, are studying the symbolic meaning of indigenous pictographs and petroglyphs, aiming to create new ways of communication between native people and modern scientists to safeguard and valorize their cultural diversity.

He is involved in the search for extraterrestrial intelligence, including the founding of SETI, mounting the first observational attempts at detecting extraterrestrial communications in 1960 in Project Ozma, developing the Drake equation, and as the creator of the Arecibo Message, a digital encoding of an astronomical and biological description of the Earth and its lifeforms for transmission into the cosmos. The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. The equation was written in 1961 by Frank Drake, not for purposes of quantifying the number of civilizations, but as a way to stimulate scientific dialogue at the first scientific meeting on the search for extraterrestrial intelligence (SETI). The equation summarizes the main concepts which scientists must contemplate when considering the question of other radio-communicative life. It is more properly thought of as an approximation than as a serious attempt to determine a precise number. Criticism related to the Drake equation focuses not on the equation itself, but on the fact that the estimated values for several of its factors are highly conjectural, the combined multiplicative effect being that the uncertainty associated with any derived value is so large that the equation cannot be used to draw firm conclusions. Drake made the first systematic search for signals from communicative extraterrestrial civilizations. Using the 25 m dish of the National Radio Astronomy Observatory, Green Bank in Green Bank, West Virginia, Drake monitored two nearby Sun-like stars: Epsilon Eridani and Tau Ceti. In this project, which he called Project Ozma, he slowly scanned frequencies close to the 21 cm wavelength for six hours per day from April to July 1960. The project was well designed, inexpensive, and simple by today's standards. It detected no signals. Soon thereafter, Drake hosted a "search for extraterrestrial intelligence" meeting on detecting their radio signals. The meeting was held at the Green Bank facility in 1961. The equation that bears Drake's name arose out of his preparations for the meeting. "As I planned the meeting, I realized a few day[s] ahead of time we needed an agenda. And so I wrote down all the things you needed to know to predict how hard it's going to be to detect extraterrestrial life. And looking at them it became pretty evident that if you multiplied all these together, you got a number, N, which is the number of detectable civilizations in our galaxy. This was aimed at the radio search, and not to search for primordial or primitive life forms." - Frank Drake The ten attendees were conference organizer J. Peter Pearman, Frank Drake, Philip Morrison, businessman and radio amateur Dana Atchley, chemist Melvin Calvin, astronomer Su-Shu Huang, neuroscientist John C. Lilly, inventor Barney Oliver, astronomer Carl Sagan and radio-astronomer Otto Struve. These participants commemorated their first meeting with a plaque at the observatory hall.

My Piper Tri-Pacer PA-22 project is coming along nicely but I have come to the point where I needed to start thinking about ADS-B solutions. Thanks to all my Patreon supporters! You make all of this possible. https://www.patreon.com/sciworx --------------------------- Tesla Referral Link https://ts.la/storm93833 Amazon Wishlist https://www.amazon.com/hz/wishlist/ls/1FANK5SZGX9HR Social Media https://twitter.com/SciWorx https://www.facebook.com/SciWorx/ https://sciworx.tumblr.com/ https://www.instagram.com/sciworx/ https://medium.com/@sciworx Video Details --------------------------- skyBeacon is a 2020 compliant, near zero install, Class B1S ADS-B UAT transmitter and WAAS GPS integrated into a wing tip position light. The power transcoder decodes replies from legacy Mode C transponders. 14 CFR §91.227 compliant. Smart phone configurable over WiFi. skyBeacon is a revolutionary new way to equip ADS-B. Simply replace your existing navigation light with skyBeacon and you are ADS-B compliant for 2020. Automatic Dependent Surveillance–Broadcast (ADS–B) is a surveillance technology in which an aircraft determines its position via satellite navigation or other sensors and periodically broadcasts it, enabling it to be tracked. The information can be received by air traffic control ground stations as a replacement for secondary surveillance radar, as no interrogation signal is needed from the ground. It can also be received by other aircraft to provide situational awareness and allow self-separation. ADS–B is "automatic" in that it requires no pilot or external input. It is "dependent" in that it depends on data from the aircraft's navigation system. ADS–B is being incorporated in various jurisdictions worldwide. It is an element of the United States Next Generation Air Transportation System (NextGen), the Airports Authority of India upgrade plans in line with the ICAO Global Plan Initiatives and Aviation System Block Upgrade (ASBU), and the Single European Sky ATM Research project (SESAR). ADS–B equipment is mandatory for instrument flight rules (IFR) category aircraft in Australian airspace; the United States requires many aircraft (including all commercial passenger carriers and aircraft flying in areas that required a transponder) to be so equipped as of January 2020; and, the equipment has been mandatory for some aircraft in Europe since 2017. Canada uses ADS–B for surveillance in remote regions not covered by traditional radar (areas around Hudson Bay, the Labrador Sea, Davis Strait, Baffin Bay and southern Greenland) since January 15, 2009. Aircraft operators are encouraged to install ADS–B products that are interoperable with US and European standards, and Canadian air traffic controllers can provide better and more fuel efficient flight routes when operators can be tracked via ADS–B.

The broadcast ranges from observatories in Europe to observatories in Australia, and from an observatory orbiting in space to one sunk a mile underground at the bottom of a gold mine in the South Dakota Badlands. Some 30 distinguished astronomers are seen at work in their observatories. Among them are Sir Bernard Lovell at Jodrell Bank, England; Thomas Gold at the giant Arecibo radiotelescope, high in the hills of Puerto Rico; Bernard Mills hunting pulsars at Mount Stromlo in Australia; Jan Cort at Dwingeloo in Holland; Maarten Schmidt at Palomar; Sir Martin Ryle at Cambridge, England; Tom Kinman at Lick, California; Frank Low in his Lear Jet “observatory” flying his telescope above cloud cover; and Donald Kniffen sending up a gamma-ray tracking chamber in a balloon. The birth and death of stars, the possibilities of hitherto unknown sources of energy out in the stars, and quasars that act in ways nothing known in physics can explain, are examined by Robert Dicke of Princeton, Jesse Greenstein of Palomar and Mount Wilson, Allan Sandage and Bernard Pagel of the Royal Greenwich Observatory, physicist Philip Morrison of M.I.T., and Richard Henry’, rocket researcher at the United States Naval Research Laboratory. Did the universe begin in a week’s time, with one explosion, as proponents of the “Big Bang” theory argue, or is it continually expanding in a relatively orderly way through all time, as defenders of the “Steady State” theory maintain? The controversy, which has implications for theology as well as for the movement of man out into space, is described in the broadcast. The broadcast goes to Japan to visit the home of Tsutomu Seki, the amateur astronomer who teaches classical guitar for a livelihood and who in 1965, with Kaoru Keya, discovered the Ikeya- Seki comet. Featured in the broadcast is a studio reconstruction of a section of the universe, with 100 stars hung in their proper perspective in space. The astronomical proportions involved in the scale replica are so vast that one foot of studio floor equals three light years—or 18,000,000,000,000 (18 trillion) —miles. The script of “The Violent Universe” was written by Nigel Calder.

The Orbiting Astronomical Observatory (OAO) satellites were a series of four American space observatories launched by NASA between 1966 and 1972, managed by NASA Chief of Astronomy Nancy Grace Roman. These observatories, including the first successful space telescope, provided the first high-quality observations of many objects in ultraviolet light. Although two OAO missions were failures, the success of the other two increased awareness within the astronomical community of the benefits of space-based observations, and led to the instigation of the Hubble Space Telescope.

If you ever wanted to take the first steps to make your own hydrogen at home, here is how you start. A Hoffman Apparatus is a piece of glass lab equipment that is great for electrolysis experiments, mostly used to generate hydrogen and oxygen from water. It is a really useful addition to your home lab. A Hoffman Apparatus is an apparatus for electrolyzing water, invented by August Wilhelm von Hofmann (1818–1892) in 1866. It consists of three joined upright cylinders, usually glass. The inner cylinder is open at the top to allow addition of water and an ionic compound to improve conductivity, such as a small amount of sulfuric acid. A platinum electrode is placed inside the bottom of each of the two side cylinders, connected to the positive and negative terminals of a source of electricity. When current is run through Hoffmann's apparatus, gaseous oxygen forms at the anode and gaseous hydrogen at the cathode. Each gas displaces water and collects at the top of the two outer tubes.

Hofmann voltameters are no longer used as electrical measuring devices. However, before the invention of the ammeter, voltameters were often used to measure direct current, since current through a voltameter with iron or copper electrodes electroplates the cathode with an amount of metal from the anode directly proportional to the total coulombs of charge transferred (Faraday's law of electrolysis). The modern name is "electrochemical coulometer" or more popularly called a "Hoffman Apparatus." Although the correct spelling of Hofmann contains only one 'f' and two "n", it is often incorrectly depicted as Hoffman.

The Cybertruck was unveiled at the Tesla Design Studio in Los Angeles on 21 November 2019. During the unveiling, Tesla claimed that the Cybertruck's "Armor Glass" windows were virtually unbreakable, but two windows shattered when Franz von Holzhausen threw a metal ball at them. Musk jokingly exclaimed that "the ball didn't make it through" and "we'll fix it in post". He later explained that the windows were damaged because in an earlier demonstration, the door was hit by a sledgehammer and that cracked the base of the glass. The fact that the rear windows shattered too was explained by microscopic cracks developed in both windows during previous ball throwing tests before the unveiling. At the end of the presentation, the Tesla Cyberquad, an all-terrain vehicle (ATV), was driven onto the bed of the Cybertruck using built-in ramps in the tailgate. The Cyberquad was plugged into the Cybertruck's onboard power outlet to charge the Cyberquad's batteries. The ATV will be available for sale as an optional package with the Cybertruck This is an archival video of that unveiling event. #Tesla #Cybertruck #EV Thanks to all my Patreon supporters!

According to Musk, the design of the Cybertruck was inspired by Blade Runner and the Lotus Esprit driven by James Bond in The Spy Who Loved Me, which doubled as a submarine. The Cybertruck uses unibody construction (termed an "exoskeleton" by Tesla) like most passenger cars, rather than the body-on-frame construction which is typical of trucks, as a standard vehicle frame would conflict with the under-floor battery pack. It uses unusually thick 3 mm (1⁄8 in) 30x-series cold-rolled stainless steel body panels, which cannot be stamped like conventional automobile parts. The panels can only be bent along straight lines, resulting in a very distinctive faceted design which has been called "low-poly" or likened to origami. This material is the same material SpaceX (also owned by Musk) uses on their Starship Rocket, because it distributes stress more evenly and allows for more interior volume. Earlier design concepts for Cybertruck had included using titanium for the outer panels, but this was later switched to stainless steel for additional strength, using an alloy that was developed in-house by Tesla. The Cybertruck unveiling event was covered heavily by traditional media and online blogs/social media. In social media, many commentators expressed dislike of the sharp contours and unusual exterior of the Cybertruck. Tesla, Inc. stock was down 6% following the Cybertruck announcement. On 23 November 2019, Elon Musk tweeted that Tesla had received 146,000 pre-orders in the first 1.5 days after the unveiling—each requiring a US$100 refundable deposit—with 42% choosing the dual-motor configuration, 41% choosing the tri-motor configuration, and 17% choosing the single-motor configuration. The number reached 250,000 on 26 November. Additionally, a video of the Cybertruck pulling a rear-wheel-drive Ford F-150 uphill in a tug of war resulted in 14,000 comments and 619,000 likes on Twitter. Various news outlets pointed out this was not a result of superior horsepower or torque, but simply due to the Cybertruck being heavier. In January 2020, Automobile Magazine named Cybertruck the "Concept Car of the Year" for 2019.

Such images may or may not be considered pictograms in the general sense. A pictograph is a pictorial symbol for a word or phrase. Pictographs were used as the earliest known form of writing, examples having been discovered in Egypt and Mesopotamia from before 3000 BC. Early written symbols were based on pictographs (pictures which resemble what they signify) and ideograms (symbols which represent ideas). Ancient Sumerian, Egyptian, and Chinese civilizations began to adapt such symbols to represent concepts, developing them into logographic writing systems. Pictographs are still in use as the main medium of written communication in some non-literate cultures in Africa, the Americas, and Oceania. Pictographs are often used as simple, pictorial, representational symbols by most contemporary cultures. Pictographs can be considered an art form, or can be considered a written language and are designated as such in Pre-Columbian art, Native American art, Ancient Mesopotamia and Painting in the Americas before Colonization. One example of many is the Rock art of the Chumash people, part of the Native American history of California. Some scientists in the field of neuropsychiatry and neuropsychology, such as Mario Christian Meyer, are studying the symbolic meaning of indigenous pictographs and petroglyphs, aiming to create new ways of communication between native people and modern scientists to safeguard and valorize their cultural diversity.

The astronomical proportions involved in the scale replica are so vast that one foot of studio floor equals three light years—or 18,000,000,000,000 (18 trillion) —miles. The script of “The Violent Universe” was written by Nigel Calder. Narrator is Carl Sagan, professor of astronomy at Cornell, with Robert MacNeil, PBL special correspondent in London who is also a reporter for the BBC. This 5-part series from archive.org has been restored for your viewing pleasure by SciWorx. You are welcome! The Orbiting Astronomical Observatory (OAO) satellites were a series of four American space observatories launched by NASA between 1966 and 1972, managed by NASA Chief of Astronomy Nancy Grace Roman. These observatories, including the first successful space telescope, provided the first high-quality observations of many objects in ultraviolet light. Although two OAO missions were failures, the success of the other two increased awareness within the astronomical community of the benefits of space-based observations, and led to the instigation of the Hubble Space Telescope. The Lick Observatory is an astronomical observatory owned and operated by the University of California. It is on the summit of Mount Hamilton, in the Diablo Range just east of San Jose, California, United States. The observatory is managed by the University of California Observatories, with headquarters on the University of California, Santa Cruz campus, where its scientific staff moved in the mid-1960s. It is named after James Lick. Sir Fred Hoyle was an astronomer who formulated the theory of stellar nucleosynthesis. He also held controversial stances on other scientific matters—in particular his rejection of the "Big Bang" theory, a term coined by him on BBC radio, and his promotion of panspermia as the origin of life on Earth.

He is involved in the search for extraterrestrial intelligence, including the founding of SETI, mounting the first observational attempts at detecting extraterrestrial communications in 1960 in Project Ozma, developing the Drake equation, and as the creator of the Arecibo Message, a digital encoding of an astronomical and biological description of the Earth and its lifeforms for transmission into the cosmos. The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. The equation was written in 1961 by Frank Drake, not for purposes of quantifying the number of civilizations, but as a way to stimulate scientific dialogue at the first scientific meeting on the search for extraterrestrial intelligence (SETI). The equation summarizes the main concepts which scientists must contemplate when considering the question of other radio-communicative life. It is more properly thought of as an approximation than as a serious attempt to determine a precise number. Criticism related to the Drake equation focuses not on the equation itself, but on the fact that the estimated values for several of its factors are highly conjectural, the combined multiplicative effect being that the uncertainty associated with any derived value is so large that the equation cannot be used to draw firm conclusions. Drake made the first systematic search for signals from communicative extraterrestrial civilizations. Using the 25 m dish of the National Radio Astronomy Observatory, Green Bank in Green Bank, West Virginia, Drake monitored two nearby Sun-like stars: Epsilon Eridani and Tau Ceti. In this project, which he called Project Ozma, he slowly scanned frequencies close to the 21 cm wavelength for six hours per day from April to July 1960. The project was well designed, inexpensive, and simple by today's standards. It detected no signals. Soon thereafter, Drake hosted a "search for extraterrestrial intelligence" meeting on detecting their radio signals. The meeting was held at the Green Bank facility in 1961. The equation that bears Drake's name arose out of his preparations for the meeting. "As I planned the meeting, I realized a few day[s] ahead of time we needed an agenda. And so I wrote down all the things you needed to know to predict how hard it's going to be to detect extraterrestrial life. And looking at them it became pretty evident that if you multiplied all these together, you got a number, N, which is the number of detectable civilizations in our galaxy. This was aimed at the radio search, and not to search for primordial or primitive life forms." - Frank Drake The ten attendees were conference organizer J. Peter Pearman, Frank Drake, Philip Morrison, businessman and radio amateur Dana Atchley, chemist Melvin Calvin, astronomer Su-Shu Huang, neuroscientist John C. Lilly, inventor Barney Oliver, astronomer Carl Sagan and radio-astronomer Otto Struve. These participants commemorated their first meeting with a plaque at the observatory hall.

My Piper Tri-Pacer PA-22 project is coming along nicely but I have come to the point where I needed to start thinking about ADS-B solutions. Thanks to all my Patreon supporters! You make all of this possible. https://www.patreon.com/sciworx --------------------------- Tesla Referral Link https://ts.la/storm93833 Amazon Wishlist https://www.amazon.com/hz/wishlist/ls/1FANK5SZGX9HR Social Media https://twitter.com/SciWorx https://www.facebook.com/SciWorx/ https://sciworx.tumblr.com/ https://www.instagram.com/sciworx/ https://medium.com/@sciworx Video Details --------------------------- skyBeacon is a 2020 compliant, near zero install, Class B1S ADS-B UAT transmitter and WAAS GPS integrated into a wing tip position light. The power transcoder decodes replies from legacy Mode C transponders. 14 CFR §91.227 compliant. Smart phone configurable over WiFi. skyBeacon is a revolutionary new way to equip ADS-B. Simply replace your existing navigation light with skyBeacon and you are ADS-B compliant for 2020. Automatic Dependent Surveillance–Broadcast (ADS–B) is a surveillance technology in which an aircraft determines its position via satellite navigation or other sensors and periodically broadcasts it, enabling it to be tracked. The information can be received by air traffic control ground stations as a replacement for secondary surveillance radar, as no interrogation signal is needed from the ground. It can also be received by other aircraft to provide situational awareness and allow self-separation. ADS–B is "automatic" in that it requires no pilot or external input. It is "dependent" in that it depends on data from the aircraft's navigation system. ADS–B is being incorporated in various jurisdictions worldwide. It is an element of the United States Next Generation Air Transportation System (NextGen), the Airports Authority of India upgrade plans in line with the ICAO Global Plan Initiatives and Aviation System Block Upgrade (ASBU), and the Single European Sky ATM Research project (SESAR). ADS–B equipment is mandatory for instrument flight rules (IFR) category aircraft in Australian airspace; the United States requires many aircraft (including all commercial passenger carriers and aircraft flying in areas that required a transponder) to be so equipped as of January 2020; and, the equipment has been mandatory for some aircraft in Europe since 2017. Canada uses ADS–B for surveillance in remote regions not covered by traditional radar (areas around Hudson Bay, the Labrador Sea, Davis Strait, Baffin Bay and southern Greenland) since January 15, 2009. Aircraft operators are encouraged to install ADS–B products that are interoperable with US and European standards, and Canadian air traffic controllers can provide better and more fuel efficient flight routes when operators can be tracked via ADS–B.
