Compared with GPS, Beidou is better.

Before the Beidou system was developed, the global navigation system was monopolized by American GPS, but in the last century, China suffered a loss, which made China make up its mind to develop its own navigation system, so Beidou system was born.

Beidou system has excellent performance.

As a navigation system independently developed by China, Beidou system has played a key role in the military field. Then, when civil vehicles use Beidou system in the future, can the error within a few seconds be reduced? Yang Changfeng said that this technology is still difficult to achieve at present. If it can be matched with powerful foundation reinforcement system and lane auxiliary facilities, it can reach this level, even without driving.

Beidou system has spent decades of efforts of researchers in China. After decades of construction, it has been presented to everyone. Beidou system has a wide coverage and a large scale, which can be deeply integrated with people's lives and bring more convenience to people's lives. Thousands of users and all-weather satellites form a tight encirclement. This is particularly important for the economic development of China. Data show that the output value of satellite navigation industry may reach 400 billion yuan in 2020.

Who is better than GPS?

Many people outside are comparing Beidou system with GPS system. The Beidou system developed by China is equipped with a more complex three-track hybrid constellation. The most important one is short message service, which is not available in any system except Beidou. Its signal transmission distance is longer, and its positioning accuracy is the same as that of GPS in the world, but its performance has surpassed that of GPS in some fields. Yang Changfeng said that it is very likely to install SMS service on Huawei's mobile phone at the end of the year, which is another development opportunity for Huawei.

Almost all parts of the Beidou system are independently developed by China. In terms of Beidou chips and modules, China has made a great breakthrough in technology, which is no different from other products in the world. Yang Changfeng said that scientific research institutions in China have been working hard to develop chips. Beidou core used in Beidou can be called China core, which will reduce power consumption and greatly improve accuracy in the future.

The service life of a Beidou satellite can reach 12 years, and China will build a navigation system that is more in line with the needs of Chinese people in 2035. Providing technical support for the future development of artificial intelligence, China will continue to take off. After so many years of development, many technologies in China have been in the leading position in the world, which is tantamount to a huge challenge for the United States, which will definitely try its best to contain China.
