GPS is a successful example of the realization of dual-use of modern high-tech. GPS has gradually evolved into a worldwide high-tech industry. In the field of GPS applications, the proportion of vehicle applications is the largest among all applications, accounting for about 50% of the total. GPS vehicle application system is generally divided into two major industries: vehicle GPS monitoring and positioning system and vehicle GPS navigation system. We mainly focus on vehicle dispatching and monitoring system.

　　The application of vehicle GPS monitoring and positioning system in China has gone through an extremely undulating and slow development road. It has experienced several ups and downs. The first wave was from 1994 to 95, when tens of companies came to seize the market of GPS monitoring and positioning system for vehicles, including a few companies with economic strength, but few of them were really successful. Many companies had to quit the industry. The second period is the period of consolidation, consolidation, enrichment and improvement of the GPS vehicle positioning monitoring system market. From 1998 to 2000, the vehicle GPS monitoring and positioning system market showed a rapid growth momentum. At this time, the market gradually became mature. The technology of the GPS vehicle positioning and monitoring system in China has been greatly improved and developed. The communication network, as the bottleneck problem of the system, has found a new way out by using the SMS service of the GSM public network, This is undoubtedly of great benefit to the top grade and scale, and the vehicle GPS monitoring and positioning system market has been greatly promoted. Since 2003, the price of the modules in the GPS vehicle monitoring unit has been greatly reduced, and the technical level has become increasingly mature,

　　GPS vehicle positioning monitoring system has begun to show a rapid development trend. By the end of 2005, more than 10 provinces and 50 cities across the country had started to build their own GPS vehicle monitoring and dispatching platforms, and there was a trend of explosive growth. The government's support has further promoted the development of the GPS industry, especially in some industries, such as long-distance passenger transport, taxi, public security, logistics, car rental and so on. The development trend of GPS is rapid and conservative. By the end of 2005, The total number of vehicles loaded nationwide has reached 500000, with a market value of billions.
