Research on Double-satellite/Road Integrated Positioning Technique and Fast Orienting Technique Based on Double-satellite Positioning System;

This paper is more systematic studies of the development process and the principle of the system location technology in the intelligent transportation, and adopts the positioning technology of the intelligent transport systems;focuses on the principle of the GPS / DR integrated positioning technology.

In the paper,it analyzes the actuality of vehicle location and navigation system by marketing study,and gives a conclusion of GPS/DR integrated positioning by lab.

The Research of Portable Combined Positioning Terminal Technology Based on FPGA;

By analysis of positioning properties about various setting styles, this paper presents a general positioning system model which is called the combined positioning system with two directions and two distinct related units, based on it a widely used general analysis method and its mathematic model about fixture setting error is built.

Research on Technologies of Intelligent Vehicle Integrated Location and Route Navigation;

This paper introduces the basic operation of GPS technology and DR technology,their own advantages and disadvantages,advantages of integrated location technology of GPS/DR,and research means of information fusion.

In this paper we proposed an integrated navigation system data fusion scheme which is based on wavelet entropy.

The structure and the system principle of the GPS/MR integrated navigation system are introduced.
