 What kind of world will Beidou +5G open?

According to the analysis of the insiders, the reason for the delay of launch is not the satellite itself. It is probably the big problem of the launch of the three-stage rocket - the ignition problem during the three-stage separation. Worldwide, satellite delay is not an example. Li said that at present, the system is in good condition and we have the ability to find out the cause as soon as possible and reorganize the launch.

If the launch is successful, it means that Chinas Beidou No. 3 system has been assembled and the global networking will be officially completed. At that time, it can provide high-precision and reliable positioning, navigation and timing services for all kinds of users around the world. Beidous performance is only the embodiment of its value. The more important significance of this satellite is that China has built an independent and controllable satellite navigation system, and Beidou will also become a national card.

Industrial chain ready

Beidou satellite navigation system is a global satellite navigation system independently developed and operated by China. It is also one of the only four satellite systems in the world that can provide global navigation and positioning. The other three are GPS in the United States, GLONASS in Russia and Galileo in Europe.

As a strategic project of China, it has been deployed in three stages since the 1990s, from serving China and the Asia Pacific region to launching 35 satellites by the end of this year to achieve global services.

Beidou satellite navigation system consists of three parts: space segment, ground segment and user segment.

The space segment and the ground segment of the satellite navigation industry chain are the national core infrastructure, which are mainly invested by the state. The space segment mainly includes satellite development and launch, and the space segment is dominated by subordinate units of Aerospace Science and technology group. The ground segment is mainly set up to track and control the operation of Beidou navigation satellite, which is composed of several ground stations such as master control station, time synchronization / injection station and monitoring station. The development and production of the ground segment is led by China Electronics Technology Group.

The market-oriented features of the products and systems in the user segment are obvious, and the participants include subordinate companies of the military industry group, local state-owned enterprises participating in the military, and many civilian enterprises participating in the military. The navigation user segment can be subdivided into upstream, midstream and downstream industries.

1) Upstream basic components are the key link of independent control of the industry. As the most critical part of independent control, basic components are mainly composed of baseband chip, RF chip, board card, antenna, etc;

2) Midstream mainly includes terminal integration and system integration, which is the focus of industrial development;

3) Downstream includes many solutions and operation and maintenance services to provide industry applications, mainly divided into industry market, mass market and special market.

In 2018, the upstream, middle and downstream output value of Beidou industrial chain accounted for 11%, 47% and 42% respectively, with the highest proportion of midstream industries. The proportion of downstream output value rose from 25% in 2015 to 42% in 2018, with a very rapid growth.

Beidou chips, modules and other key technologies have made breakthroughs. According to the report from CCID consultants, the 28 nm RF baseband integrated SOC chip supporting beidou-3 new signal has been widely used in the field of Internet of things and consumer electronics. The latest 22 nm RF dual frequency positioning chip has market-oriented application conditions. The full frequency integrated high-precision chip is under development. The worlds first chip fully supporting beidou-3 civil navigation signal system The high-precision baseband chip tianqin II was officially released in Beijing. The performance of Beidou chip will reach a new level, and the performance index is equivalent to that of similar international products.

By the end of 2019, the cumulative sales volume of domestic Beidou navigation chip modules has exceeded 80 million, and the sales volume of high-precision boards and antennas has occupied 30% and 90% of the domestic market share, and has been exported to more than 100 countries and regions.

The equipment supporting Beidou is becoming more and more popular. According to the data in the first quarter of 2019, 82 of the 116 domestic mobile phones newly applied for access to the network support Beidou Positioning, and the support rate of Beidou Positioning reaches 70%. Moreover, 5g base stations of operators basically support the dual timing mode of GPS + Beidou, which can be used as the main backup for each other.

Beidou + 5g opens a new market space

In the future, Beidous industrial chain will develop well for a long time driven by domestic substitution, favorable policies, the rise of science and technology cycle and demand. First of all, the demand for domestic alternatives is stronger than ever before, and satellite navigation system is an important step. Secondly, with the completion of the whole Beidou system, the downstream application market will be further opened. Combined with the new round of industrial revolution brought by 5g, the process of Beidou navigation system entering the civil market will be accelerated. It is believed that in the future, Beidou industrial chain will form four markets of one billion million million including high-precision surveying and mapping, UAV and time service, smart car and mobile Internet of things navigation. Finally, China has a huge domestic demand market, developed mobile communication market and a large number of mobile terminals, which is a huge advantage of Beidou navigation development.

The main function of Beidou navigation, first of all, is the function of navigation and positioning. Without the enhancement of image base and ground, the accuracy can reach about 7-8 meters. The second is precise timing. Using high-precision rubidium atomic clock and hydrogen atomic clock, we can provide users with nanosecond level precision time synchronization. In addition, short message communication is a unique function of Beidou system. Under the condition of no network signal, it is similar to the function of sending short message, so it can realize the communication problem without network signal.

u201dBeidou + 5g + intelligent technology will open a huge space for digital economy and intelligent society.

In the specific application scenario, highway transportation is one of the most mature and widely used industries of satellite navigation system in China. In addition, there are also major application fields such as surveying and mapping, aviation, power, agriculture, etc. in 2019, the application market share of Chinas satellite navigation industry accounts for 60.8% of the whole industry. With the continuous improvement of positioning accuracy of Beidou navigation system and the further stability of chip performance and price, the application of Beidou navigation system in smart city, public security, industrial and agricultural machinery, unmanned system and other fields will be further deepened, and the industrial development space will be further expanded.
