| 摘 要： | GPS/DR组合导航在户外GPS信号较好的情况下,可以提供精度较高的定位导航,但人的活动范围不仅仅是户外,会经常穿梭、停留于各种建筑物中。此时,GPS信号几乎无法获得,DR会因长时间得不到修正而导致发散,因此,GPS/DR系统无法在室内提供长时间高精度的导航信息。基于上述原因,文章研究基于到达时间差（TDOA）的定位算法,利用超声传感器实现室内TDOA定位,并与DR系统进行组合,校正并改善DR系统误差发散问题,以增强导航系统的定位能力。

| Abstract: | GPS/DR integrated navigation system can provide better position accuracy when the outdoor GPS signal is better,but the man＇s territory is not limited to outdoor,they often go across or stop inside all kinds of bulidings.At this time,the GPS signal can not be achieved,DR will induce the position results to diverge,thus GPS/DR cannot provide long-time and high-accuracy navigation information indoor.Based on the above reason,this paper studies the positioning algorithm based on time difference of arrival（TDOA）,uses ultrasonic sensor to finish indoor TDOA position which integrates with DR system and improves DR system＇s performance to enhance navigation system＇s position capability. |
