【正文】 7 is closer to people39。s license number, and set number, etc., in the control center of the electronic map display. Meanwhile, the control center of the system administrator can check the operating conditions of vehicles, vehicle scheduling and reasonable according to traffic flow. Theft of vehicles, for example, are generally divided into static and dynamic vehicle antitheft vehicle tracking two. The former refers to the owner left the car, parked vehicles suffered theft, destruction, and move the vehicle through its own monitoring system alerts the monitoring center to the GPS and cell phone owners automatically contact the police and so on. The latter can be stolen on a moving vehicle location tracking, condition monitoring, vehicle track records, and even control of vehicle power and off oil. (2) GPS devices for consumer products. The miniaturization of chip technology, production costs, volume, and favorable factors such as reduced power consumption, making GPS products altar, deep into people39。s GPS satellite receiver according to the information received to calculate the vehicle39。s development China GPS market presents two major trends. (1) the movement of car navigation as the core objective of monitoring, management and service system. 6 In GPS applications, a greater proportion of vehicle applications. The first GPS vehicle tracking and vehicle applications are generally divided into two major vehicle navigation system. However, when Motorola launched collection vehicle navigation and tracking in one vehicle information system, it bees the direction of development. GPS vehicle location monitoring system mainly from the navigation application and the center control in two ways. GPS Vehicle Monitoring System is a technology, wireless munication technologies and geographic information system technology in an integrated vehicle management system. General industry, monitoring the user39。s NTT Mobile Communications Network Inc., KDDI, and the United States, Sprint, Verizon, tele work panies, the letter operators have also begun or plan to provide GPSbased mobile phone location services. With the country39。s largest potential market for satellite navigation. After ten years of development, China39。s various applications on the rise. This is why the price of consumer GPS products have fallen so fast and functional numerous mercial and special GPS equipment remained at a high level of reason. Especially in the mercial GPS market, the rapid development of a variety of software, an increasing number, these are the proliferation of GPS products yield the fundamental driving force. In the consumer GPS market, the software is not the main reason affecting the cost, so the hardware prices drop, the retail price of GPS products continue to reduce the causes. In 2021, the National Institute of Public Administration carried out the survey, the global GPS market each year has reached 12 billion . dollars. With the unit price down to 100 . dollars less, GPS will be a lot to civilian. In addition, GPS will drive market growth is also related to the development of chips for the GPS chip will be strong growth in recent years, and bear the price pressure will be more moderate than other semiconductor products. 2. our satellite navigation market situation and development trend 1, Market and Development GPS satellite navigation technology in the late 80s to China, the key to Geodetic (mapping, exploration), marine fisheries and the areas of vehicle location monitoring has been more widely used. GPS applications in the world, the largest proportion of vehicle applications, now more than 40% of the total. 1996 to 1997 is the GPS vehicle tracking systems market, the period of adjustment and enrichment. Mainly public security, finance and other departments to use its dedicated conventional radio stations (or different frequency simplex radio) munication system and the simulation cluster system, the ten cities in the country three or four armored and built a financial vehicle tracking system on 5 Public Security. 1998 to 2021 GPS vehicle tracking system of rapid market growth. With the GSM digital mobile munication system in China39。 final, currently has to offer an integrated GPS chip and wireless munication technology panies are still few, and handset manufacturers are willing to use existing solutions, or other selfdevelopment is still uncertain. 4 After nearly 20 years of development, GPS products have been gradually transformed into consumer electronics products, and expanded beyond the scope of application of daily munication, PDA, positioning information. However, in order for now, because singlechip GPS receiver technology, price and market applications are not yet mature, therefore, optimistic view of this market development, such as the GPS IC design techniques can reach a cell phone or PDA required minimum size and power consumption, cost reduction, and builtin GPS whether the new phone is able to cause consumers problems still must be careful indepth assessment. 4, the global GPS Market Forecast It is estimated that the world has more than 100 panies are developing a variety of GPS user receiver. Large quantities of OEM board receivers from 1995, the price of the standard positioning service receiver 150 . dollars per unit down to the current 4050 dollars. With the price drop receiver, GPS market will be like a PC, the market as the trend of exponential growth. Currently, GPS market presents two trends: First, the hardware prices continued to decline each year。 Second, GPS ponent operation will dramatically increase the phone39。s report, in 2021, these two types of products in the GPS applications market bined ratio of about %, to 2021, will grow to %, other produ
