摘要
室内定位是当前定位导航领域的热点课题,对导航领域有重要的补充作用。伪卫星技术已日渐成熟,从伪卫星出发研究室内定位技术,解决室内定位难题,开展伪卫星室内定位算法研究,主要从观测量提取和定位解算两方面进行问题分析,提出遍历定位算法及改进方案,分析其理论可行性,并对其进行改进以适应工程实现需求,结合实践给出试验数据,验证室内定位效果。
As an important component of navigation field,indoor location is an emerging hot topic.At present,pseudosatellite technology is extensively used to realize positioning.To achieve the combination of the two technologies and address the challenges of indoor location,the problem is analyzed from two aspects:observation data extraction and position resolution.The ergodic algorithm is proposed,and its theoretical feasibility analyzed.The algorithm is also improved to adapt to engineering implementation.Its effectiveness for indoor location is verified by test data based on practice.
