1. A new visual dead reckoning positioning method is presented for mobile robot, which is based on lines and single feature points. 提出了一种基于直线和单特征点的视觉推算定位方法。
2. Dead Reckoning Trailer (field AI) Identifies where an object should be located at present, given its last reported course and speed. 推测行进路线（AI区域）表示根据目标最新报告的进程和速度一个目标应该驻扎的位置。
3. An embedded remote terminal based on GPRS technology for ships in inland rivers was designed, based on GPS and secondary dead reckoning for ships' positioning. 利用船位推算方法辅助GPS进行船舶定位，设计了基于GPRS无线通信的嵌入式内河船舶远程通信终端。
4. By setting up kinematics model of mining vehicle on uneven terrain and measuring dynamic parameter by compass, we can use the model for dead reckoning and get correct orientation of mining vehicle. 通过建立非平坦地形上采矿车的运动学模型，采用电子罗盘等传感器测量采矿车的动态参数，依据运动学模型进行航位推算，从而实现采矿车的准确定位。
5. Doppler-sonar is a dead - reckoning system. 多普勒-声纳是一种推测航位系统。
