What is the BeiDou system

The BeiDou system is a global satellite navigation system developed by China, and it is also the third mature satellite navigation system after GPS and GLONASS. BeiDou Satellite Navigation System (BDS) and American GPS, Russian GLONASS and European Union GALILEO are the suppliers that have been recognized by the United Nations Satellite Navigation Commission.

Beidou Satellite Navigation System (hereinafter referred to as BeiDou System) is a satellite navigation system built and operated independently in China, focusing on the needs of national security and economic and social development. It is an important national space base that provides all-weather, all-day and high-precision positioning, navigation and timing services for global users. Facilities.

Beidou belongs to the satellite positioning system. The BeiDou satellite positioning system is a regional navigation positioning system established by China. The system consists of three parts: three (two working satellites and one backup satellite) BeiDou positioning satellite (BeiDou-1), the ground part mainly of the ground control center, and the BeiDou user terminal.

The BeiDou system is the world's first satellite navigation system to provide three-frequency signal services. The use of dual-frequency signals can weaken the impact of ionosphere delay, while the use of three-frequency signals can build a more complex model to eliminate the high-order error of ionosphere delay.

The BeiDou system is a global satellite navigation system independently built and operated by China. It is the only navigation system in the world composed of three types of orbital satellites. On June 23, the last global network satellite of BeiDou-3 successfully entered the predetermined orbit.

What is Beidou?

1. What does Beidou mean? It is a "romantic star", and the Big Dipper has been guiding people since ancient times; it is an "innovation star", and active positioning and short message communication are the innovations of China's Beidou; it is the "Star of China", which is our own navigation satellite.

2. Beidou is composed of the seven stars of Tianshu, Tianxuan, Tiange, Tianquan, Yuheng, Kaiyang and Yaoguang. The ancient Han people connected these seven stars and imagined them as the shape of a bucket for scooping wine in ancient times.Tianshu, Tianxuan, Tianji and Tianquan are composed of fighting bodies, which is called Kui in ancient times; Yuheng, Kaiyang and Shaguang are composed of fighting handles, which are called ladle in ancient times.

3. The Big Dipper is composed of seven stars, namely Tianzhu, Tianxuan, Tiange, Tianquan, Yuheng, Kaiyang and Yaoguang. The ancestors connected these seven stars and imagined them into the bucket shape of scooping wine in ancient times. Tianshu, Tianxuan, Tianji and Tianquan formed the fighting body. In ancient times, it was called Kui and Doukui; Yuheng, Kaiyang and Shaguang formed into the fighting handle, which was called the bucket in ancient times.
