Abstract

The invention relates to the field of wireless communication, and provides a method and a system for high-precision positioning for a common mobile terminal. The method comprises the following steps that: A, the mobile terminal sends positioning request and current GPS positioning data of the mobile terminal to a control center in real time through a wireless communication network; B, the controlcenter calculates a virtual reference station according to the current position of the mobile terminal, and calculates a high-precision positioning result of the mobile terminal by using a data processing center; and C, the control center sends the high-precision positioning result to the mobile terminal in real time through the wireless communication network. The method and the system calculate the high-precision positioning result of the mobile terminal by using the data processing center, and realize real-time data transmission by using the wireless communication network, thereby realizingthe high-precision positioning of the common mobile terminal.

Description

1. Technical field [0001] The present invention relates to the communication field, and more specifically, to a method and system for high-precision positioning of a mobile terminal. 2. Background technology [0002] Currently, Global Positioning System (GPS) technology is widely used in fields such as agriculture, forestry, water conservancy, transportation, aviation, surveying and mapping, security, military, electric power, communication, and urban management. Satellite positioning can be divided into two categories: navigation type and high-precision (positioning) type according to accuracy and purpose. The navigation type is mainly used for the navigation of various moving targets, and the accuracy requirement is low, generally several meters or meters. The positioning accuracy of the high-precision type can reach centimeters or even millimeters, and it plays a very important role in many fields of scientific research, national defense and national economic constructio...
