Chinese analogue of GPS

02.01.2013

The People's Republic of China has officially opened for public use in the Asia-Pacific region its alternative to global positioning systems GPS and GLONASS called Beidou (BeiDou Navigation Satellite System, abbreviated as BDS). The name of the Beidu system is translated from Chinese as the constellation Ursa Major. Previously, access to it was limited only to the military and government agencies of the PRC. Representatives of the official circles of the country said that by 2020, the percentage of use in the Celestial Empire of the national positioning system will be 70-80%. Analysts say that in 2011, the share of the GPS system in the local market was 95%.

Beidu allows you to determine the location of the user with an accuracy of 10 meters, and the speed of movement with an accuracy of 20 centimeters per second. The signal synchronization time is about 50 nanoseconds. However, while the cost of electronic filling for the Beidu system is several times higher than similar solutions for GPS. However, prices tend to fall, and the Chinese government believes that local manufacturers will quickly master the production of mass-produced consumer systems for Beidu.

There are currently six satellites of the Beidu system in orbit. The PRC authorities plan to bring the constellation to 46 satellites over the next decade. The first BDS satellite was launched by China in 2000. The last of the current constellation was launched into orbit on October 25, 2012. A preliminary version of Beidu has been in use since 2003 for traffic control, weather forecasting and the needs of national rescue services.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

The oldest bacteria on earth 14.09.2016

Australian geologists led by Allen Nutman (Allen Nutman) discovered in Greenland stromatolites - fossils of cyanobacteria - which today are the oldest traces of life on Earth.

A layer of snow melted in Greenland revealed fossils several centimeters in size, which are obviously traces of bacteria that lived on Earth 3,7 billion years ago, that is, from a geological point of view, "shortly" after the appearance of the planet, which occurred approximately 4,5 billion years ago.

This finding is indicative of how early life began on Earth and is consistent with previous studies that have also dated the origin of life to about 4 billion years ago.

The Scientific Russia portal has repeatedly written about what hypotheses scientists express about the origin of life on our planet. Thus, it was suggested that strong solar activity contributed to the emergence of life, and that life was brought to Earth from Mars. Perhaps the discovery of traces of ancient bacteria will help scientists figure out the details of the development of life.
