Intelligent transportation navigation system is a system which exploits computer technology and communication technology to improve the traffic ability, traffic resistance, safety factor of the road and deal with the emergent accident.

Marine seismic navigation data processing technique;

Through collecting and testing navigation data by mobile mapping system,this paper discussed the application of mobile mapping system for collecting and updating urban navigation data.

In view of the flying test requirements of a rocket, a real-time massive navigation data sampling-processing and storing system was designed and realized based on the structure of DSP+FPGA+NAND FLASH.

Outlier detection in traffic data sets serving for intelligent transportation system;

A view of the development of traffic data collection technique is described and characteristics of the technique are analyzed and classified in this paper.

According to a lot of domestic and foreign research on the quality control of traffic data through the ITS real-time detection,this paper summarizes the types of real-time data errors through the ITS detection,introduces the concept and key technology of the ITS data quality control,and discusses the algorithm in the key technology of the ITS data quality control with a good example.

The navigation database and performance database were designed.

This paper introduced the definition,technical characteristics,key technology and implementation process of navigation database.

It introduces the way and steps to construct the navigation database of major subject web resources in universities by the TPI system,and provides a solution to the digital library resources management.
