基于伪卫星技术的室内外一体化定位系统设计

Design of indoor and outdoor integrated positioning system based on pseudo satellite technology

多源融合高精度定位,是国家安全和新兴产业无人化智能战略的关键技术。《国家卫星导航产业中长期发展规划》明确将“融合多种技术,提升城市、峡谷和室内外无缝定位导航服务能力”作为重点战略任务。传统的室内定位方法UWB、蓝牙AOA存在个人信息泄漏、系统容量不高等方面的问题。基于此,文章特设计并开发了一款基于伪卫星技术的室内定位基站和室内外一体化终端,有效地解决了这一问题,为市场提供了可靠的端到端解决方案。

Multi-source fusion high-precision positioning is the key technology of unmanned intelligence strategy for national security and emerging industries. The Mid-and long-term Development Plan for The National Satellite Navigation Industry clearly takes "integrating various technologies to improve the capability of seamless positioning and navigation services in cities, canyons and indoors and outdoors" as a key strategic task. Traditional indoor positioning methods UWB and Bluetooth AOA have problems of personal information leakage and low system capacity. Based on this,this paper designs and develops an indoor positioning base station and indoor and outdoor integration terminal based on pseudo satellite technology, which effectively solves this problem and provides a reliable end-to-end solution for the market.
