model of vehicular autonomic navigation system and dead reckoning (DR) algorithm based on two-step recursive filtering are proposed in this paper.───给出了基于两步递推滤波的车辆自主式导航系统模型及其航位递推算法。

Russ Miller of University of Michigan is at the Robotics Rodeo to shows off a personal dead-reckoning, or navigation, system.───拉斯密执安大学米勒是在机器人罗德奥以炫耀个人死推算，或导航，系统。

Whenever the vehicle loses the GPS fix on its position, it can fall back on dead-reckoning navigation from its radar odometer.───车辆抓不到自身GPS定位点的时候，也可以转为使用雷达里程计的航位推算来导航。
