GPS is the abbreviation of the global positioning system. It is a new generation of precision satellite positioning system established with the development of modern science and technology. With the development of our country’s economy, automobiles are gradually entering every Chinese family. After years of development and cultivation, the market for onboard GPS systems has also entered a period of scale development. According to the relevant market research report, the vehicle-mounted GPS system usage rate in Japan is as high as 59%, and Europe and the United States are about 25%. By the end of 2007, the number of cars in China had reached 23 million, but less than 600,000 vehicles were equipped with GPS navigation devices, and the vehicle-mounted GPS system contained less than 3%, far below the average level in foreign countries. This also shows that the potential market for China's car GPS industry is very large. The data shows that by 2008, China will at least double the number of cars installed with GPS systems in China, and the output value will exceed RMB 25 billion. FAW, Second Automobile, Shanghai Volkswagen, General Motors, etc. have adopted onboard GPS navigation systems as standard equipment in luxury cars or ordinary cars.
1. Development status of China's car GPS market 1.1 China's GPS vehicle market is still in its infancy From the 1980s onwards, China began to develop vehicle-mounted GPS technology. From the perspective of system technology and product quality and maturity, China's GPS vehicle-mounted GPS devices The development of the market is still in its infancy. Compared with the market of vehicle tracking systems, in-vehicle navigation systems are more immature. For example, real-time traffic information release and perfect navigation electronic map providing and updating mechanisms all lack efficient and practical solutions and approaches.
1.2 GPS Vehicle System Rear Mounting Market The GPS vehicle system installed on the main market can be divided into two ways: front loading and rear loading. The front loading system is incorporated into the vehicle's accessory product before leaving the factory. The rear loading system is installed on the vehicle during use. At present, China's vehicle-mounted system market is still in the start-up phase of development. If the navigation terminal is used as a standard, the cost of the vehicle will increase. However, the demand for GPS equipment from users is not certain, and automobile manufacturers must take relatively large risks. Therefore, it is undoubtedly a more sensible strategy to provide car users with a flexible choice in the form of post-installation.
Currently, the number of cars in China is about 23 million. This part of the vehicle is a potential market for rear navigation terminals. Therefore, the aftermarket will remain the mainstream of the market in the next few years. Compared to the post-installed equipment, the vehicle-mounted front-loading equipment can completely integrate the navigation system and the in-vehicle system, and has undergone rigorous testing before leaving the factory. Its stability is much higher than that of the post-installed equipment. As the consumer market continues to mature, the proportion of the aftermarket will gradually decline.
So far, the market for onboard GPS systems has not developed as fast as people expected, and the entire market is still in its infancy. There are four main factors that restrict its development.
2.1 Consumer demand is not strong In terms of travel habits, China's auto users are significantly different from developed countries. In the United States and Japan, people travel hundreds of kilometers in daily driving distances, and most Chinese car owners only have 1/10 of their daily travel radius, and most of them travel to and from the fixed road to their place of residence. As China's auto users are more aware of the road conditions, this determines that there is no strong market demand for product use, as there is no country with a well-developed market for car GPS navigation products.
2.2 Lack of industry standardization The issue of standardization is the core issue of the industrialization of vehicle-mounted GPS vehicle tracking systems. At present, GPS products and operating systems of different companies cannot be universal, compatible, and networked.
The main GPS industry standards in the market are: "Highway Global Positioning System (GPS) Measurement Specification / JTJ People's Republic of China Industry Standards", "SEG Navigation National Uniform GPS Service Standards" and standards set by Zhejiang and other provinces. It is difficult for customers to choose the latest and best products in the market and upgrade the technology. In addition, the strength and reputation of enterprises involved in this field are uneven, and the quality of service needs to be improved. These problems hinder the promotion and application of the product.
2.3 Product price is too high One of the reasons that the price of GPS-based products in the car cannot be rapidly popularized in the Chinese market is that the development of navigation products that can be accepted by most consumers in China is the major task of major GPS manufacturers. At present, the price of the single-chip receiver in the high-end market of the mainstream GPS system in the market is about 8,000 yuan, the mid-market price is about 5,000 yuan, and the low-end single-cell receiver price is about 2,000 yuan. Even the average price of a simple in-vehicle system is 2500-4000 yuan, which makes a large part of the potential consumers frightened.
2.4 Maps to Be Open In the car GPS navigation system, the most important thing is the electronic map provided by the product. However, in China's consideration of national security, the government strictly controls the map data.
The first major trend in the development of automotive GPS technology is the frequency diversity technology, which is actually being implemented during the replacement of aging satellites by second generation GPS systems. After completion, the modern satellite constellation will provide civilian users with three new positioning signals. In addition, the "Galileo" plan launched by the European Union in March 2002 also adopted such technology.
The second major trend is to overcome Radio Frequency Interference (RFI). The power of GPS broadcasts is particularly low, typically 10 to 16 watts, and it is very easy to be disturbed by the surrounding RF signals and not work properly. The on-board GPS receiver will penetrate the noise by matching the received ranging code with the phase of the locally stored replica code. When the phases are the same, the receiver can use the timing signal as an accurate reference so that it can be positioned accurately.
The third major trend is to install an integrated mechanical system that guarantees that the positioning error is less than a certain value. Using differential on-board GPS technology, the system will obtain the latest error correction information from geosynchronous orbit communication satellites. The correction data comes from the ground reference receiver. In the past, the error of on-board GPS was 2 meters, and it will be smaller now.
