摘要
惯性技术虽然能完全自主的输出定位信息,但误差随着时间而增加,只能短时间的保持精度,而卫星定位在室内环境下无法有效提供连续定位信号的缺陷,因此将卫星和惯性定位组合,再加入区域无线定位可以形成无缝定位的组合方式。采用这3种组合方式实现无缝定位,并设计了不同定位场景的解决方案,并进行了仿真实验和跑车实验。实验的结果都表明,这种组合方式既增加了定位的适用范围,又达到了无缝定位的要求。
Inertial technology can completely independently output location information, but the error increases with time, keeping the accuracy of only a short time. Satellite positioning in indoor environment cannot effectively provide continuous positioning signal. So the combination of satellite and inertial positioning, adding area wireless positioning can form seamless positioning. The three combinations to achieve seamless positioning, design solutions and different location scenes, and the results of simulation and experiment. The experimental results show that, this combination not only increases the scope of positioning, but also achieves seamless positioning requirements.
