How good is the Beidou navigation system? Come learn about Beidou Navigation, which is better than GPS

Beidou Navigation System, do you think it is just a navigation system? Don’t be surprised when I say that it also has various hidden skills! Now let me tell you in detail.

As we all know, our country’s infrastructure capabilities are the strongest in the world. my country's infrastructure construction is world-famous for its fast speed, high quality, and short construction period. It is called "infrastructure maniac" by other countries in the world. Among many engineering constructions, the most basic and important thing is accurate surveying and mapping. Only accurate surveying and mapping can ensure the quality and accuracy of construction. Traditional measurement methods are obviously no longer suitable for the development speed of this ever-changing world. Then, there must be other surveying and mapping tools to solve the arduous task of measurement.

Have the bright stars in the dark night with clear skies ever made you daydream about your beautiful profile? But do you know? In the starry sky that you are obsessed with admiring, the dazzling stars also hide some "stars" that are not outstanding. They are satellites that bear important tasks. Although his appearance is not outstanding, he is the only "candidate" who can take on this important task. It can not only easily handle the complex surveying and mapping activities of large-scale construction activities. Daxing Airport, which was completed last year, used the Beidou system at the beginning of construction. Not only did the construction accuracy reach millimeter level, it also shortened the construction time of the airport.

Time is the most important catalyst for the development of modern society. For ordinary people, time errors have almost no impact on them. But for some large-scale automation systems, time errors are tantamount to disaster.

The Beidou system has no such concerns at all, because its "heart" is composed of high-precision atomic clocks. An atomic clock is a device that utilizes the stable characteristics of atomic transition frequencies to obtain precise time and frequency signals. Its research and development involves many disciplines such as quantum physics, electricity, and structural mechanics. Currently, only a few countries in the world have independent research and development capabilities. Spaceborne atomic clocks are mainly used in navigation systems and are divided into three types: hydrogen atomic clocks, rubidium atomic clocks and cesium atomic clocks.

International navigation systems all use a rubidium atomic clock paired with a cesium atomic clock or a rubidium atomic clock paired with a hydrogen atomic clock. Beidou system is no exception. Even if it runs for millions of years, its error will not exceed 2 seconds.

In large-scale activities such as the operation of the national transmission grid, financial transactions, and large-scale scientific experiments, the Beidou system provides extremely accurate timing services to ensure the normal operation of the entire country; due to the positioning of the Beidou system It is very accurate. Many satellites are connected to each other, forming a large "network". Through the data transmitted back by this "network", people can obtain precise details of any place at will. This is a commonly used navigation function for people. Not only navigation, Beidou also plays an important role, which is to predict geological disasters. Beidou satellites can monitor mountains, rivers, and calculate data to predict disasters. Officially due to the role of the Beidou system , China can already predict geological disasters, such as landslides, earthquakes, etc. in advance.

After talking about these "high-end" functions of the Beidou system, I have to talk about its less eye-catching "small functions", how to deal with them? That is the ordinary short message function, that is, the SMS sending function. Don't underestimate this feature. When you and your friends are bathing in the sea breeze, the high sail takes you to ride the wind and waves, and the sea breeze lifts your long flowing hair; the sky in the distance is as smooth as a mirror. At this time you find that you can't find your companion. What's worse, you are lost. At this time, the Beidou system can help you. It brings you a glimmer of hope in the vast ocean. Sufficient signals and smooth networks allow you to finally reunite with your companions, putting aside the fear of unknown dangers.

The Big Dipper guides the direction of the North Star forever, and the Beidou navigation system guides people's direction and never stops!
