Robust Dead-Reckoning in Urban Areas with Tightly Coupled Integration of GPS-Doppler and INS

With the development of various driver assistance systems using vehicle position information, improvement of positioning accuracy is desired. Global positioning systems GPS, widely used as a positioning system, can provide accuracy within a few meters in suburban areas. However, in urban areas, this accuracy can be degraded to ten meters or more because of the reflection and blocking of GPS signals by tall buildings. In order to maintain accurate positioning in such an environment, it is important to develop a method of dead-reckoning which is robust against the surrounding buildings. In this paper, the authors report on a new method of dead-reckoning the authors have developed in order to improve robustness in urban areas. With this method, the error of dead-reckoning in urban area has been reduced to less than 1/60 that of the conventional method.
