Abstract
En 中文
This paper presents a method for correcting dead reckoning parameters, which are heading and step size, for a pedestrian navigation system. In this method, the compass bias error and the step size error can be estimated during the period that the global positioning system (GPS) signal is available. The errors are used for correcting those parameters to improve the accuracy of position determination using only the dead reckoning system when the GPS signal is not available.-The results show that the parameters can be estimated with reasonable, accuracy. Moreover, the method also helps to increase the positioning accuracy when the GPS signal is available.
