On November 20, the Glory 9X Beidou Quest was officially held in the China ASEAN Beidou/GNSS (Nanning) Center, with Zhang Chi (Weibo ID: Occam Razor), a famous communication expert, and Wu Di, a postdoctoral fellow in navigation discipline of Wuhan University and the general head of Beidou technology as the presenters, The media and experts present shared the application and development of Beidou navigation system in mobile navigation and location services. It is reported that the navigation and positioning service of Glory 9X has been applied to Beidou Navigation. On the basis of the old B1I civil band, the B1C band has been added, which has stronger anti-interference ability, more accurate and stable navigation and positioning, and can achieve positioning accuracy within 3 meters in practical applications.

Navigation multi scenario application Beidou navigation post attack
With the rapid development of mobile phones, compared with the changes in appearance and camera, the upgrade of navigation module is relatively "hidden" and difficult to be perceived by users. However, in some special scenarios, the navigation gap will be reflected. For example, in the tunnel, some mobile phone navigation will be offset and disconnected, which is caused by the loss of navigation signal. Through continuous efforts in recent years, the Beidou navigation system has greatly improved its accuracy and detection rate, which can avoid migration, disconnection and other phenomena to the greatest extent.
At the event site, communication experts and science popularization major V Zhang Chi (Weibo ID: Occam Razor) introduced that the three generations of Beidou have continuously made progress mainly because they have made two innovations: first, the hydrogen atomic clock developed by our country has replaced the rubidium atomic clock of the United States, which is 10 times more accurate than that of the United States, and once developed, it is more advanced than that of the United States. Second, an interstellar link has been made, which means that all 35 stars have been connected. For example, I control the signal of a satellite in Beijing, and the information of this satellite can be transmitted back and forth among the 35 satellites, thus solving the problem of global deployment of satellite networking.

Beidou satellite navigation system is one of the four major satellite navigation core suppliers in the world. Compared with the GPS system of the United States, GLONASS of Russia, GALILEO of the European Union and other systems, Beidou has a faster layout and rapid technology improvement. It has taken a late attack and quickly caught up with the international advanced level. At present, Beidou has 35 satellites in orbit, two more than the U.S. GPS satellites in orbit. It has been able to provide high-precision and reliable positioning, navigation and time service for all kinds of users around the world, 24/7, 24/7. In the Asia Pacific region, the positioning accuracy can be up to 2.6 meters, and the speed measurement accuracy can be up to 0.05 meters/second. The third generation network of Beidou will be completed next year, which will be able to provide more stable and accurate global positioning services.

According to Beidou experts, Beidou also has SMS (Short Message Communication Service) service, which is not available in other navigation systems. SMS service can help users to calculate the distance. Users only need to send positioning requests and information to GEO satellite, and then the satellite will forward them to the ground center. The ground center will complete the user's location calculation, and send the location and related information back to the user through satellite. This can avoid the disadvantage of short transmission distance, and improve the communication quality. When users face extreme situations, When the network is completely lost, it can still locate accurately.
Multi frequency navigation signal with Glory 9X positioning accuracy can be measured within 3 meters
According to the 2019 Terminal Insight Report released by China Telecom a few days ago, Glory 9X has the strongest positioning performance in the 1500 yuan gear. According to field experts, Glory 9X uses the joint positioning of Beidou and GPS. The two systems are independent and do not interfere with each other, but the error can be reduced after superposition. Compared with other Android phones, Glory 9X not only supports B1I (civil signal), but also is compatible with the new signal frequency band of the third generation of Beidou B1C. The B1C signal frequency band is more anti-interference, and the whole scene positioning is more accurate. According to the outdoor measurement of the media, the positioning accuracy can reach within 3 meters.

In addition to the advantages of mobile phone hardware, Glory 9X also has AI smart communication 2.0 functions. Use scenarios are identified through AI intelligence, such as the need to locate car hailing in the elevator. Due to the weak signal in the elevator, other Android phones cannot accurately locate. Glory 9X can achieve intelligent switching, quickly recover signals, and combine with Beidou navigation to provide users with better positioning and navigation experience. According to the media at the conference, on November 26, Glory will soon release the flagship of the V30 series 5G, or will launch the "super navigation function". It can be predicted that under the development of 5G network in the future, high-speed network will be combined with Beidou high-precision positioning, and V30 series will bring more portable and accurate services, providing a flagship brand new experience.
