Why is Beidou navigation named after Beidou and what is the significance?

The term "Beidou" refers to the seven stars of the Big Dipper discovered by the ancients in China. The name Beidou is to reflect that Beidou navigation is independently developed by China.

Because Beidou is the name of China's satellite series, it is also important to name navigation Beidou meaning.

The name of the Big Dipper is named after the seven stars of the Big Dipper. Because the Big Dipper is familiar to everyone, this naming can increase people's perception of the Big Dipper.

The Beidou Navigation System is a global satellite navigation system developed by China itself, and is the third mature satellite navigation system after the GPS system of the United States and the GLONASS system of Russia. The system consists of three parts: space satellite, ground central station and user terminal, and its coverage includes Chinese mainland and its coast, Taiwan, Nansha and other islands and reefs, the Sea of Japan, parts of the Pacific Ocean and some surrounding areas.

The Beidou Navigation Satellite System can provide all-weather, high-precision, and large-scale real-time positioning services for users in the service area, and its positioning accuracy is generally tens of meters. If differential positioning technology is adopted, the positioning accuracy of key areas can reach within 10 m, and the speed measurement accuracy is better than M s, which is basically close to the positioning level of the GPS system in the United States.

The Beidou Navigation Satellite System is a global satellite positioning system developed by China itself, and is the third mature global satellite system after the GPS of the United States and GLONASS of Russia. The accuracy of this system is already comparable to that of the American GPS, and it has been widely used in many fields.

1. Beidou Navigation Satellite System The Beidou Navigation Satellite System is divided into three components, namely the space segment, the ground segment and the user segment, which can provide efficient, high-quality and high-precision services for all kinds of users on a global scale and around the clock. Among them, the space segment is composed of a number of geostationary orbit satellites and geosynchronous satellites, the ground segment includes the main control station and monitoring station, and the user segment includes basic products such as Beidou and chips, modules, antennas and other satellites compatible with Beidou.

Second, the overall performance of the excellent Beidou satellite navigation is that the Beidou system in China and surrounding areas can independently provide satellite navigation and positioning services, and its overall performance can be equivalent to GPS. At present, the coverage area of the Beidou system has been expanded, the positioning accuracy is also improving, and the speed measurement accuracy has changed from meter seconds to meter seconds. Since 2017, the construction of the Beidou-3 system has progressed to ultra-high-density launches, and the accuracy of Beidou satellites has become higher and higher, and the number of satellites in orbit has reached 39.

3. Widely used in many fieldsAt present, the Beidou satellite navigation system has been widely used in many fields, including water conservancy, agricultural construction, meteorology, highways, traffic monitoring, etc. For example, in marine fisheries, fishermen can know the precise route of the fishing vessel and the location of the surrounding fishing grounds through the Beidou navigator on the fishing boat, and can also send text messages in case of emergency to communicate with the management department on land. With the Beidou navigation system, fishermen can also know exactly what they want to do with their specific fishing plans.

Dear readers and friends, in fact, in some official applets, we can measure how many Beidou satellites there are above your area anytime and anywhere, you might as well give it a try.

We will use navigation in our daily travel, even if we are very familiar with this route, we will use it from time to time, and the power of navigation comes from satellites, satellite global coverage, you can plan the best route from one location to another, and the positioning before the most is only GPS, only open this can be connected to the satellite to receive signals, now we have our own navigation system, called Beidou, so what is Beidou satellite navigation? How powerful? Beidou satellite navigation is a system that can plan the best route for vehicles and carry out precision strikes for missiles, no less than the creation of the atomic bomb.

We used to only know GPS, because this is one of the first few navigation, it can be accurate to about 5 meters, that is, I in Africa as long as the missile hits you I can let you die in Asia, this is a terrible use in the military, the reason why it is called Beidou or follow our Chinese like ancient culture for the sake of the context, we all know the Big Dipper, that is a few very powerful stars, so the implication is that Beidou navigation is also very powerful, and with Beidou we will choose more, After all, your own stuff is the best.

The gold nest and silver nest are not as good as their own kennels, used to describe this system is the best, but this system is not a very vegetable thing, it can wrestle with those old navigation systems, it is enough to see its strength, in the past we used GPS because there was no navigation, but felt that there was no practical use in creating this money, but once the United States directly turned off GPS, resulting in the plane could not fly, missiles did not know to hit **, so we became blind, So with his own navigation, you can see how good he is.

In recent years, our country's scientific and technological strength has been vigorously developed, but there is still a gap compared with those old developed countries, such as the manufacture of chips, we do not have the technology to manufacture lithography machines, and there is no way to produce chips, so see the situation clearly, don't be arrogant.

Beidou Satellite Navigation is a navigation system independently developed by China, and its accuracy is very high, which has exceeded GPS.

Beidou satellite navigation, equivalent to the GPS system of the United States, can capture images and positioning functions from time to time according to satellites operating in space, and also for our Dongfeng Express navigation, the accuracy can reach a range of several meters.

The Beidou Navigation Satellite System is a global satellite navigation system developed by China and the third mature satellite navigation system, which can provide high-precision navigation services around the world.

Beidou's navigation and positioning will be more accurate, in the area where the cellular or communication signal Shankai is not covered, you can also use short message service, provided in the area where no one lives cautiously, such as desert forests, mountainous areas, these areas can have a good effect, when the user is in distress, you can also notify the user's location and condition to the rescue team; I think the significance of Beidou is that our country has its own global navigation satellite system, which can meet the needs of China's social and economic development.

I think the biggest difference between Beidou and other navigation is that Beidou detection is clearer, and it will change accordingly according to some road conditions at any time, and he plans the route on the earth very clearly; I think the significance of Beidou lies in the fact that it is more clear and clear to depict the territory of our country and make exploratory discoveries in all areas of the transportation group.

The Beidou system is mainly developed by China. It also provides global services and plays an important role in agriculture, forestry and fisheries, which can reduce disasters and provide disaster relief. The Beidou system has protected the security of our country, and at the same time developed our country's science and technology, which has allowed us to improve the filial piety of infrastructure and materials.

Beidou Navigation is a satellite navigation system independently developed by China, and its meaning can be interpreted from the following aspects:

Direction guidance: The Beidou navigation system provides accurate positioning and navigation services through a group of satellites to help people determine their own position and heading. It means that Beidou navigation provides people with reliable direction guidance to help them move forward and explore.

National honors: Beidou navigation is one of the important achievements of China's independent innovation and development, representing China's strong strength in the field of science and technology and the promotion of its influence, demonstrating the glory and independent ability of the country.

Practical value: Beidou navigation has important application value for transportation, geological survey, resource management, disaster rescue and other fields, providing more convenient, safe and efficient navigation services for the society, implying the contribution of Beidou navigation to the actual interests of people's lives and social progress.

All in all, Beidou navigation means direction guidance, national honor and practical value, and symbolizes China's major achievements in the field of navigation technology and a new chapter in national development.
