Farewell, Americans’ GPS! From May, navigation will use China’s Beidou
Mobile phone navigation, WeChat sharing location, finding maps of street food, etc., GPS in the United States has almost monopolized everything.
Nowadays, Beidou’s domestic layout is getting stronger and stronger, and GPS is about to step aside!
According to media reports, the Beidou satellite navigation system has entered the intensive launch stage of global networking, and the first phase of "National One Network" has been officially accepted, which can provide real-time dynamic centimeter-level precision positioning services in 21 provinces in China.
At that time, under the empowerment of Beidou, smart cities, autonomous driving, smart logistics, etc. will achieve large-scale commercial use.
Beidou Map APP, accurate to within 1 meter, accurate to specific lanes
According to the reporter from Shapingba District, Chongqing, the Beidou Map APP is expected to be launched on May 1, and its navigation function can be accurate to within 1 meter, allowing it to clearly locate specific lanes.
Beidou Map APP is a basic location-based service tool based on Beidou satellite precision navigation service, which can provide mobile, real-time positioning and navigation, as well as location-based clothing, food, housing, transportation and business information services for the majority of users.
According to the relevant person in charge of Beidou Internet of Things Company, "Beidou Map has intuitive and convenient road guidance, clear and clear voice prompts, and new road signs and actual road prompts for main and auxiliary roads, roundabout islands, and expressways, so that users can understand the route situation at a glance, and can calmly deal with complex road conditions." Beidou Map can also give intelligent route optimization suggestions according to actual road conditions to improve travel efficiency.
GPS is American.
There is a prestigious club in the world that has only four members, but it has attracted the attention of heads of state and the research of many top scientists and engineers. This club is GNSS (Global Navigation Satellite System). The four members are GPS from the United States, Galileo Galilei from Europe, GLONASS from Russia, and Compass from China.
Once upon a time, in the minds of ordinary users, GPS was a positioning and navigation system, and a positioning and navigation system was GPS.
But many people don’t realize that although users around the world can access it, the control and data of the GPS system still belong to the United States.
GPS, powerful as this
The older generation, such as my father who has been driving for more than 20 years, can be called an old driver. I remember riding in the car in elementary school and junior high school, and I always love to sleep. At this time, my father will wake me up and say:
"Stop sleeping, watch the road, what if you don’t recognize the road in the future?"
Unfortunately, more than a decade has passed, and I rarely get lost, even though my phone has a powerful navigation system.
And my father, who was very dissatisfied with me sleeping in the car, has completely given up the idea of persuading me in recent years and has happily used GPS.
GPS is mainly used for two purposes, military and civilian.
Military: Almost all aircraft, tanks, precision-guided missiles, and ships in the United States use GPS.
Civilian aspects: Without GPS, the navigation of mobile phones, WeChat, and APP will be paralyzed; the national power grid will enter an unstable state; autonomous driving technology, high-precision takeoff and landing autonomous navigation of civil aviation aircraft, and precision agriculture are all dreams.
The GPS system belongs to the United States, and over-reliance on GPS will inevitably lay hidden dangers. Such as GPS interference and deception.
GPS belongs to the United States, Beidou belongs to us.
In order to break the monopoly of the United States in this field, Russia and Europe have respectively built GLONASS and Galileo satellite navigation systems.
China Beidou is a new member, but also the most dynamic member, and Beidou has a huge impact on our lives!
One is the complex constellation system.
It is reported that Beidou has two unique featuresOffice:
Beidou is the only satellite navigation system that uses geostationary orbit, geosynchronous orbit and medium orbit. GPS, GLONASS, and Galileo all use medium orbit only.
The second is the short message system: Beidou’s receiver can communicate with the satellite and issue a 140-word short message, just like the "text message" that people usually use now, which can not only locate, but also display the location of the publisher.
In military terms, all the places where the US GPS can be used are in the direction of Beidou.
The performance of Beidou is no less than that of the US GPS.
What is "Beidou"? The beautiful woman scientist of the Chinese Academy of Sciences after 80 will analyze it for you
Hello, Big Dipper.
According to the surging coverage, at 01:56 on March 30, our country used the Long March 3B carrier rocket (and the upper stage of Expedition 1) at the Xichang Satellite Launch Center to successfully launch the 30th and 31st Beidou navigation satellites in the way of "one arrow and two stars". These two satellites are the seventh and eighth networking satellites of our country’s Beidou-3. China’s Beidou satellite navigation system has entered the intensive launch stage of global networking. So far, a total of 31 satellites have been launched, and it can provide services for global users in 2020.
The first phase of the construction of the Beidou ground-based enhancement system "National One Network" in our country has officially passed the acceptance, which can provide sub-meter-level precision positioning services nationwide and real-time dynamic centimeter-level precision positioning services in 21 provinces in China.
We can finally say goodbye to GPS.
Industry insiders said that it is expected that in the next three years, more end points such as mobile phones, bicycles, and wearable devices will use Beidou high-precision positioning services to empower urban management and bring convenience to people’s lives.
Unmanned courier
"Drone delivery is a typical Internet of Things application, and the core technology is location-based service." The relevant person in charge of Beidou Internet of Things Company introduced that the company has developed the world’s first Internet of Things module based on Beidou communication technology, which can make location-based services accurate to the centimeter level.
Network map, independent of graphics and text
You may not see the courier brother in the future~
Positioning vehicles with sub-meter accuracy
All vehicles engaged in road passenger transportation, travel bags, and dangerous goods transportation must be equipped with electronic positioning devices, so that the traffic management department can monitor the movement status of the vehicle, and the illegal driving behavior such as speeding and breaking the ban will be automatically alerted.
The previous GPS positioning accuracy was 10 meters, and it was impossible to distinguish lanes. Since September 2014, China has started the development and construction of the Beidou ground-based enhancement system, installing Beidou equipment in street light poles, signal towers and other places to form the Beidou ground-based enhancement system.
The Beidou ground-based augmentation system and space-based satellites cooperate to achieve real-time positioning accuracy below the meter level, and large trucks will no longer dare to occupy the overtaking lane for a long time.
The elderly and children were lost and found quickly
With the Beidou navigation system, the positioning watches worn by the elderly and children will be more accurate and sensitive. The positioning information is no longer "near a certain place", but may be accurate to which floor tile you stand on.
In case the bear child is naughty and runs away from home, this time he knows where to look.
No examiner driving test is coming
With the cooperation of ground facilities, Beidou’s real-time positioning accuracy has been much higher than GPS, which provides another business with technical means, that is, the examiner-free driving test based on the Beidou system.
The current driving test items such as reverse parking already have electronic monitoring, and the alarm will be called when the line is pressed, but the road test still needs an examiner. In the future, all driving exams may be completely replaced by the Beidou system, and the Beidou receiver will be installed on the test car. Whether it is reverse parking or road test, the system will accurately record the vehicle trajectory in real time and automatically score it, which will be more strict and fair than the examiner.
Deformation monitoring of huge buildings
Fixing Beidou equipment on huge buildings such as dams, bridges, and highways can more conveniently and accurately measure their settlement and deformation. The equipment automatically receives positioning information, accumulates a month of massive positioning data, and then performs differential calculations. The positioning data with accuracy below millimeters is counted, which is much more convenient and accurate than manual measurement.
Using Beidou for deformation monitoring can also send data from remote monitoring points directly back to the base through the Beidou SMS function, reducing manual collection, and automating positioning, differential decomposition, and data return.
Applications in fisheries
In order to make it easier to call for help in case of distress, fishermen will be equipped with GPS and maritime satellite phones when they go out to sea, but it is very expensive to maintain a maritime satellite phone.
After the Beidou network in the Asia-Pacific region, fishermen installed the Beidou satellite ship end point, a key for help after encountering danger, the end point will automatically send the rescue text message with positioning information to the shore rescue team through the satellite, realizing the function of GPS + maritime satellite phone.
Is this end point expensive? The government has taken out 100 million free Beidou end points installed for 10,000 fishing boats in Liaoning, Shandong, Zhejiang and Hainan, and the direct subsidy for subsequent installation is 90%. Fishermen only need to pay 10% of the money to install it.
Beidou satellite text messages cost 30 cents, which is much cheaper than maritime satellite phones!
Application in rescue
The short message service of the Beidou system can perform emergency communication in the event of disasters such as earthquakes and damage to base stations, and can also send its location to the outside world in the absence of a signal.
The Beidou-1 system played an important role in the Wenchuan earthquake.
During the 2008 Wenchuan earthquake, Beidou played an important role.
At that time, the Beidou first-generation system had the advantage of not being affected by the ground during the earthquake, and its positioning and SMS capabilities had fully played a role. It had become the most effective communication assistant for the rescue command force and frontline rescuers, maximizing the effective use of the "72-hour golden rescue time".
Let’s use a picture to understand

The applications of Beidou listed above
Just a small aspect.
In the future, it will affect our lives in every way.
Amazing, my country!
Make a call for Beidou~
