GPS is currently one of the most widely used positioning technologies in navigation systems, but it also has its own shortcomings. For example, when the GPS terminal is located in a place with dense buildings or under a Viaduct or other harsh geographical location, the positioning signal is easy to lose, and it is often difficult to obtain effective positioning information.

　　Wireless positioning service, also known as location service, is a new type of value-added service provided by mobile communication networks. The positioning service based on mobile communication networks is to determine the actual geographical location of mobile users through the cooperation of mobile terminals and mobile communication networks (GSM/C DMA), thereby providing users with location-related service information (longitude and latitude, mobile speed, etc.), and providing it to users themselves

　　At present, the advantages and disadvantages of two main wireless positioning technologies, namely GPS based and cellular mobile communication network based positioning, are introduced. Then, the mobile hybrid positioning technology GPSone, which combines the above two wireless positioning technologies, and its application status are introduced. It indicates that GPSone technology has improved the availability, sensitivity, accuracy, and positioning time of positioning, and has gradually become a widely used mobile phone personal positioning technology in the world.

　　Location service business is an emerging value-added business. This article comprehensively studies the GPSone hybrid positioning technology used in CDMA1X network and provides a deep understanding of its positioning process; On the basis of analyzing the application of existing location services in the transportation industry, GPSone positioning technology based on CDMA 1X network is introduced into the intelligent transportation vehicle positioning system. An economical design scheme is proposed and the positioning process of the intelligent vehicle positioning system is elaborated. The feasibility of the scheme is demonstrated through various aspects of analysis.
