The problem of autonomous driving and aided navigating has received increasing attention in recent years. INS/GPS integrated navigation for intelligent vehicles is developed.This system is made of GPS and INS,it is the core algorithm to make information fusion using Kalman filter.With INS aided,the navigation system has the fault-tolerant ability.Simulaton results show that the system can satisfy the needs of vehicles position and navigation.

Current GPS positioning technology is widely used in mobile positioning system, but it has many limitations, such as in order to provide accurate three-dimensional positioning the system must receive the positioning data of four GPS satellites. Based on this, we propose an approach based on CDMA 1X Communications GPS and GPSOne with a combination of new mobile positioning system. At realization of the program in the system, we make scientific researches on the two-mode switch positioning technology and some the judging criteria that the need to consider, as well as dual-mode switch to overcome errors caused by the excessive Zero Shift Algorithm Design and Implementation.

In this paper, we analyze hard x-ray in-line phase contrast imaging using Fresnel diffraction of x-ray. Then we propose a linear phase retrieval method based on Transport of Intensity equation (TIE). According to computer simulation for the process of phase contrast imaging and Phase retrieval, this method is tested on simulated images and is demonstrated to be efficient for phase retrieval in the "near-Fresnel"region.
