China GPS navigation market has great potential. As of the end of 2005, China has a car navigation equipment, vehicles less than 10 million units, compared with 30 million of the total number of vehicles, the penetration rate of less than 1%. The Japanese car vehicle navigation installation rate of 59%, Europe accounts for about 25%. 2006 should have a portable navigation market size of nearly 500 million yuan, and with the rapid market development and new brand after another, in 2009 China's auto GPS navigation system terminal sales will be close to 10 billion yuan. 2008, known as China's "3G first year." As we all know, in the domestic communications, the most fire is under trial operation of TD-SCDMA - 3G standards. As a new generation of communications technology, 3G has brought to people a lot of expectations. The overall distribution of 3G licenses, but also become a focus of common concern. In fact, the GPS navigation in the domestic sector is also undergoing a transformation, the third generation PND class navigation products came into being, has put people into a new era of navigation. Satellite navigation industry in the national economy is playing an increasingly important role, will be the Eleventh Five-Year "development of the bright spots in the" Eleventh Five-Year "period, satellite navigation and in other areas such as air, sea, rail, construction, telecommunications , electricity, etc. The application will have much room for development of satellite navigation technology trends mainly in three aspects: First, the coexistence of multiple systems of satellite navigation, the system availability is increased, the applications will be more extensive; second multi-navigation technology is used widely, mainly GPS and mobile communication base station location, top, dead reckoning technology, a combination of the application; third satellite navigation and wireless communications, and other high-tech combination, such as cellular phone embedded GPS receiver , portable PC, PDA and watches, communications, safety and consumer electronics products, fundamentally promote the overall development of IT technology.
