GPS is one of the most widely used positioning technology in navigation systems, but GPS also has its own shortcomings. For example, when the GPS terminal is densely building or under the viaduct, the positioning signal is easier to lose, and it is often difficult to obtain effective positioning information.

　　The wireless positioning business, also known as the location business, is a new type of value -added business provided by the mobile communication network. The positioning service based on the mobile communication network is to determine the actual geographical location of mobile users through the cooperation of mobile terminals and mobile communication networks (GSM/C DMA), so as to provide users' needs related service information (latitude and longitude, mobile speed, etc. ), Provide the user himself,

　　At present, the two major wireless positioning technology, which is based on GPS and the advantages and disadvantages of honeycomb mobile communication network positioning, and then introduce the mobile phone hybrid positioning technology combined with the above two wireless positioning technology-GPSONE technology and its application status, indicating that GPSONE technology has improved improved The availability, sensitivity, accuracy and positioning time consuming have gradually become the world's widely used mobile phone personal positioning technology.

　　Location service business is an emerging value -added business. This article comprehensively studies the GPSONE hybrid positioning technology used in the CDMA1X network and understand its positioning process in depth; The GPSONE positioning technology based on the CDMA 1X network was introduced into a smart transportation vehicle positioning system, which gave an economical design solution and explained the positioning process of the smart car positioning system in detail. sex.
