In the shape of the design, the Core wing broke through the traditional appearance of the other models, the Core-wing sense of movement and high-level sense of the high degree of balance, which must be improved, both in the interior styling General Lee: For such a TSP platform, indeed, is the test of the ability to integrate the same time, just She always has been mentioned in the business platform is a completely independent intellectual property platform and our platform is t
With the development of science andtechnology, GPS technology came into being, the three-dimensional navigation isthe primary function of GPS, a new car navigation system is developed on thebasis of GPS technology, GPS navigation systems and electronic maps, the radiocommunication network and computer The vehicle management information system,can achieve many of the features of the vehicle tracking and trafficmanagement, with China's economic development, and the gradual deepening of therapid construction of high-grade highways, and GPS technology in road works andtransport The application will be more extensive and in-depth, and play agreater role.3D navigation is the primary function ofGPS for navigation of aircraft, ships, ground vehicles and walkers can use theGPS navigation receiver. The car navigation system is a new technologydeveloped on the basis of GPS. It consists of a GPS navigation, and self-disciplinenavigation, microprocessor speed sensor, gyro sensor, CD-ROM drive, the LCDdisplay composition.GPS navigation is by GPS receiver receivesGPS satellite signals (three or more) to get the point latitude and longitudecoordinates, speed, time and other information. In order to improve theaccuracy of vehicle navigation and positioning, the commonly used differentialGPS technology. When the car driving to the underground tunnels, high-risebuildings, highways and other cover objects and capture the GPS satellitesignals, the system can automatically import the self-navigation system, thistime by the speed sensor to detect the moving speed of the car, through themicro-processing unit data processing directly from the velocity and time to calculatethe distance ahead, and the gyro sensor to directly detect a forward direction,the gyroscope can automatically store all kinds of data, even in thereplacement tire temporary parking, the system can also be re-set.Measured by the GPS satellite navigationand self-discipline navigation, vehicle location coordinates, the way forwardwith the actual traveling route track there is a certain error, to correct theerror between both, so that requires the use of maps and route map unifiedmatching technology, plus a map matching circuit, the vehicle traveling routeon the road of error in the electronic map real-time correlation matching, andautomatic correction, Main products: car dvd player and car dvd ,are with good quality. In this case, the map matching circuit through thefinishing process of micro-processing unit for quick, get the car in thecorrect position on the electronic map to indicate the correct driving line.CD-ROM used to store road data and other information, LCD monitors used todisplay navigation information.These advantages are small businesses andnon-professional satellite navigation and positioning the company can notreach. Therefore, after-sales service is a major factor to consider to purchaseproducts. In addition, the price of the product is one of the major factorsconsidered by consumers when purchasing products, consumers want to buy productsaffordable, but the results have not necessarily got what they wanted. On themarket today, a lot of navigation products, "cheap" but not"poor quality". The so-called ultra-low-priced navigation products,even the cost can be achieved, their products can achieve the"navigation" effect can imagine.
