Chapter 2212 Black Technology
The concept car Duan Yun mentioned is actually the Shen Xing brand sedan that they recently launched on the market. The reason why it is called a concept car is because the car in the exhibition hall has some relatively advanced electronic accessories inside.

It has been more than four years since Tianyin Group first researched the car GPS system a few years ago, and during this period, with the advancement of technology, the GPS system of Tianyin car has become more and more mature. .

Restricted by satellite accuracy and electronic maps in this era, it is still difficult for automotive GPS systems to achieve the accuracy and usability of civilian use in later generations. However, the technicians of Tianyin Group have never stopped research and development, especially the recent In the past year, Tianyin Group's car GPS system has made a major breakthrough, and its accuracy and practicality have also been greatly improved.

Participating in the research and development of the Beidou system three years ago has allowed Tianyin Group to obtain a lot of satellite communication technologies. In addition to some sensitive technologies that are kept secret by the state, Duan Yun has converted some other technologies to civilian use, and the car GPS system is a very critical one. ring.

The GPS system is a military satellite positioning system established by the United States decades ago.

On February 1978, 2, the first GPS experimental satellite was successfully launched.

In November 1978, the Global Positioning System began positioning and navigation services.

The last working satellite was launched on June 1993, 6.

On July 1995, 7, the full-featured application (full Operational Capability——FOC) was achieved
On May 2000, 5, U.S. President Clinton announced at the White House that the policy of ending the provision of sex (SA) would be terminated.This decision will immediately improve positioning accuracy, which will be better than 1 meters with a single GPS receiver.

GPS was originally established to provide precise positioning for the military, and it is still controlled by the US military today.Military GPS products are mainly used to determine and track the coordinates of soldiers and equipment traveling in the field, to navigate warships in the sea, and to provide position and navigation information for military aircraft.

Just in March of this year, something that shamed the people of the country happened.

At that time, there was a crisis in the Taiwan Strait, and the two sides of the Strait were tense. When the United States cut off the GPS, our missiles lost their direction, and the planes and ships could only rely on land radar stations for navigation. a humiliation.

In fact, the country has long been prepared for this situation. Since 1994, the country has begun to invest in the development of the Beidou satellite program, but there are still some technical bottlenecks that have not been broken through, and no positioning satellites have occurred. Therefore, China is currently Many civil aviation and military aircraft, even some precision-guided missiles, can only rely on the GPS navigation system opened by the Americans.

However, this year's Taiwan Strait crisis has undoubtedly sounded the alarm for the country again, and the R&D investment of the Beidou Project has increased again, which is three times higher than the original planned investment.

Tianyin Group, as one of the participating companies of the Beidou Project, is also responsible for very important research and development tasks. Currently, all projects are progressing as scheduled, and have been praised by higher authorities many times.

And through participating in the Beidou project, Duan Yun also obtained some technologies that can be transformed into civilian use. After being approved by the relevant security department, some positioning and communication technologies were transplanted by Duan Yun to the cars he produced, and he is planning to one day in the future When the technology is fully mature, it will be promoted and used on a large scale.

Car navigation is a very common function in the follow-up period. In this era, it was a very advanced and avant-garde technology. Due to the high technical threshold and equipment cost, it only appeared on high-end models.

In fact, as early as the 80s, this kind of GPS navigation system had already appeared in some foreign luxury brand cars, but in fact, the usability of this GPS navigation system was not good. In terms of display, there are also great limitations. Because there is no mature liquid crystal display technology, it is generally just to display the position of the vehicle with flashing red dots on a glass or plastic drawing board with a simple city map, which looks very original.

However, Tianyin Group has developed this GPS system, which is already quite advanced in technology. It uses a nine-inch LCD screen, and in the relevant software, a large number of domestic related maps are built in. Finally, the software has real-time positioning The error correction function improves the accuracy of vehicle positioning to the highest level.

In addition, in this concept car, a head-up display system appeared for the first time. In fact, the principle of this system is relatively simple, that is, through an optical projection device, the vehicle engine speed, vehicle speed, and time and date signs are projected. On the glass in front of the driver's seat, the driver can grasp the driving status of the vehicle in real time without bowing his head. This is a very avant-garde invention in the current world automobile industry.

Although the vehicles in the exhibition hall cannot be driven, they can be connected to the power supply, and they can fully experience some configurations and electronic accessories in the vehicle. After seeing the GPS system and the head-up display in the vehicle, Geerke's face revealed a difficult expression. Confident look.

"Can this kind of vehicle of yours be positioned on the city road?" At this time, Gailke entered the car and studied for a while, then raised his head and asked Duan Yun.

"Yes." Duan Yun nodded, and continued: "Although the car navigation system has already appeared in your Europe, the car navigation system developed by our company is definitely the most advanced, and the accuracy can be maintained between 10 and 20 meters. , and will carry out real-time positioning correction to keep the error within a very small range. In addition, our group company has also developed a very stable map software, so that you can go wherever you are in China , can find the route to the destination at the fastest speed, in the future, our system will also be connected to the 2G network, and the software and various routes can be updated online to realize the intelligence of the vehicle.”

"The intelligence of the car..." Hearing this, Geerke's face became more and more surprised.

Obviously, Geerke did not expect Tianyin Group to have such a powerful technology, not only in ordinary household appliances, but even in the automotive industry, there are some "black technologies" that he has never heard of.

"Technology changing life has always been a slogan of our company. Although Tianyin Group dare not say that it is the world's top technology company, in some aspects of technical strength, it will not lose to our European counterparts." Duan Yun smiled slightly, and continued: "If your company is willing to cooperate with us, I promise to give you more surprises in the future."
