America's satellite navigation system (GPS) VS Russia (Glonass) VS Galileo (Europe) VS BeiDou

     Hello, satellite navigation systems have become an important part of our daily lives. Nearly every electronic device has a satellite navigation device, including cars, mobile phones, planes, watches, and even rockets.

    There are other GPS-like navigation systems owned by the US Air Force and used in factories including ours. For example, the Russian-made Glonass Galileo satellite constellation system is owned by the European Space Agency and China founded Baidu. Check out these four satellite navigation systems and their benefits. First GPS The GPS or Global Positioning System is actually a system that uses satellites to determine position.

    Hello, satellite navigation systems have become an important part of our daily lives. Nearly every electronic device has a satellite navigation device, including cars, mobile phones, planes, watches, and even rockets.

    There are other GPS-like navigation systems owned by the US Air Force and used in factories like ours. For example, the Russian-made Glonass Galileo satellite constellation system is owned by the European Space Agency and China-founded Baidu. Check out these four satellite navigation systems and their benefits. First GPS GPS or Global Positioning System is actually a system that uses satellites to determine position.

    GPS access to factories began in 1983 with the unfortunate incident of a Soviet Su-15 fighter jet shooting down a South Korean airliner. This mistake could have been avoided. On September 16, 1984, Ronald Reagan announced that he would allow GPS to be released to the public free of charge if the aircraft had access to his GPS system in the United States, but the accuracy of the signal he is asked to lower to 100 m. Military Tactical Sustainability Advantage Blade Clinton signed into law in 2011 to stop signal interference and provide optimal accuracy up to 5 meters. Today GPS works 24 hours a day and in all weather conditions around the world. No subscription fee. Each satellite is designed to last about 10 years and weighs about 1 tonne.The GP satellite S is powered by solar cells, but also has spare or on-board batteries in anticipation of solar eclipses. increase.

    The next navigation system is glonass. Glonass is a satellite navigation system built by the Russian Space Defense Force. Built by the Soviet Union in 1976, Glonass now consists of 27 satellites, 24 of which are for navigation and 3 for experimental earth observation stations. 14.2 Russia, 1 point for Brazil and 1 point for Antarctica. Adds 8.5 points for Russia, 2 points for Brazil, 1 point for Cuba, Australia, Spain, Indonesia, Vietnam, and a trackpoint for Antarctica. , so if you combine the two systems and use them synergistically, the accuracy of your navigation will be even higher.

    The Glonass receiver can correct the site position within a range of 7-10m. In CPS, the range is 3-4m. Performing additional signal processing and averaging the results of signal reception did not reveal any significant advantage in terms of accuracy for this Russian-made navigation system compared to GPS. Almost like GPS, but with a lot better accuracy when you combine both Google Maps Nokia Here Maps and Apple Maps use your data connection to connect to GPS satellites and his Glonass. Updated modern smartphones are gradually equipped with GPS or IC Yes and Fun Glonass or Eglon fun features. It consists of turn navigation features. Location tracking and real-time location in Russia Dual navigation system Glonass and GPS are accepted as national standards. A third satellite navigation system is Galileo. This is a European navigation system. Declan is unlike GPS, Glonass Galileo is an advanced European system that guarantees global positioning and accurate time when fully deployed, offering the highest level of accuracy.

    Galileo consists of 24 satellites and 6 pairs orbiting 23,000 km above the Earth, supported by various ground sensor stations and control centers around the world. Galileo will operate with other navigation satellite constellations with various devices such as GPS Glonass Hai and Baidu for greater accuracy and reliability. Galileo will be controlled entirely by civilians, not a military agency like any other, giving independence and freedom to European citizens.

    Galileo Navigation Sovereignty will also offer new services such as clearing-go services for government applications and more accurate positioning for commercial applications. By default Galileo offers two of his frequencies. Galileo offers the most precise level of accuracy and time positioning Encryption possible up to 1 cm.

    It also minimizes the risk if another navigation satellite is damaged or disabled. The Galileo system is more accurate than BS, the Glonass is more accurate at higher altitudes, and the GPS and Glonass systems can be turned off at any time by Americans or Russians, thus helping Europe in wartime. Galileo provides an independent and reliable civilian navigation system free of charge to people all over the world. The next infinite application is the B2B navigation system, a Chinese-made navigation satellite system aimed at reducing reliance on GPS and Glonass.

    According to the Newsasia channel, the idea to develop Baidu, which means Big Dipper, was born in the 1990s when the military was trying to reduce its reliance on GPS, which was operated by the U.S. Air Force as the first Baidu satellite. Launched in 2006, its range was limited to Chinese territory, but with the increasing use of mobile devices, China attempted to join the Galileo navigation satellite project proposed by the European Union in 2003. , then withdrew and finally decided to join the satellite iPhone era focused on Baidu.

    So the second generation was launched in 2012 and its coverage covered the Asia-Pacific region. Then, in 2015, China began launching its third generation satellite, which aims to reach the entire world. It has more satellites in the system compared to GPS which only has 31 satellites. China's investment in Baidu is estimated at 10 billion. With its own development funding aimed at maintaining the security of its communications networks, China not only has more satellites to avoid GPS interference during its conflict with the United States, but also Weapon aiming and guidance have been found to be more accurate in this network. According to Chinese state media, the B distance accuracy reaches up to 10cm in the Asia-Pacific region, compared to GPS with a range of 30cm, B2 was clearly designed decades after GPS, so much from GPS experience You can learn.

    Baidu's port traffic monitoring and disaster prevention services are exported to about 120 countries, mainly to countries related to President Xi Jinping. A monthly road initiative led by Jinping to create channels for Chinese trade and investment in China. Over 70% of his mobile phones use Baidu The types of mobile phones that use Baidu in 2019 include Huawei, Oppo, Hi, Xiaomi and Vivo.

    Doing the math, it will reach 400 billion yuan, or $57 billion, this year. Yes, apart from the 4 navigation systems mentioned above, Japan and India also have their own navigation satellite constellations, but the coverage is limited in certain areas With my friends, thank you very much.
