An important year of 2012 for Car DVD Player

displays and display products; divided into 120-degree wide-angle, 150-degree wide-angle camera shot angle range, the now well-known domestic enterprises in constant traffic logger product line, according to industry professionals, the function complete, excellent quality located in the high-end.

May 1 this year, the People's Republic of China on Road Traffic Safety Law was implemented. Should the need for the adjustment of the upper law, Guangdong Province on Road Traffic Safety Management Regulations "in the original regulations be amended. Provisions of the new provincial regulations will force the eight categories of key vehicle to promote the installation of GPS travel logger: heavy-duty trucks registered in the province, semi-trailer tractor, transport of dangerous goods vehicles, the construction units of bulk materials vehicles, school buses, coach cars engaged in road operation of passenger motor cars, not the province of registration, but operating in the province of the construction units of bulk materials car.

 During the 2012 Big Dipper, the reporter visited a number of exhibitors and new exhibitors publish in-depth understanding, but also have a further understanding of the industrialization process of the Big Dipper.

2012 is the Big Dipper to the application of 13 stars in the Big Dipper has launched the same time, the Beidou civil field-oriented products have gradually increased, although the use of the Big Dipper is still higher than the GPS there is some discrepancy, but we can find the Big Dipper in the process of industrial transformation, already the focus of development to come to civilian areas.

The Big Dipper will be the theme of the application of the Big Dipper, so many manufacturers are closer to the topic to publish their own's Beidou products. However, the reporter found that the navigation and positioning products, most of the Big Dipper and GPS dual-mode signal, which is at the same time be able to Beidou signals and GPS signals. Although car dvd player and in car dvd player the dual-mode signal on the navigation equipment to improve accuracy, improve signal reliability advantages, but the devices are also many problems facing the manufacturing cost is high, signal instability in a single Big Dipper. In fact, for navigation and positioning equipment is not in itself a good thing, the first device manufacturing costs for the improvement of the cost will inevitably faced with the improvement of the selling price, which is no doubt the the Beidou industry is in transition to industrialization caused a certain unfavorable factors. Secondly, the navigation and positioning equipment released from the show, most of the equipment size huge, is not conducive to carry this application of dual-mode has a direct relationship.

However, despite these problems, we have found from many pleased. First, the accuracy of the Big Dipper in East Asia than GPS, which means that, in China and Southeast Asia, Compass has strong advantages of the GPS. Second, these devices due to the Big Dipper and GPS dual-mode signal than in the past, positioning accuracy and signal coverage greatly enhanced. Of course, the biggest advantage of the Big Dipper have a communication function in its own presence Beidou satellite and mobile phone text messages. Coupled with the large coverage of the Big Dipper, which will undoubtedly provide greater protection operations in the deep desert crowd.
