本文提出了一种用于行人导航系统的航位推算参数（航向和步长）的校正方法。在该方法中，罗盘偏差误差和步长误差可以在全球定位系统（GPS）信号可用期间被估计。这些误差用于校正这些参数，以提高在GPS信号不可用时仅使用航位推算系统的位置确定的精度。结果表明，该方法能合理、准确地估计出各参数.此外，当GPS信号可用时，该方法还有助于提高定位精度。
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.
