摘　　要：通导融合是综合定位、导航和授时(positioning,navigation,timing,PNT)体系发展的重要组成部分和关键方向。以PNT体系需求以及用户典型应用为牵引,研究了联合定位的融合算法;采用北斗和第五代移动通信技术(5th generation mobile communication technology,5G)这2种PNT手段,设计并构建了2类典型试验场景:室内5G信号定位场景、室外北斗+5G联合定位场景。围绕定位精度这一关键指标开展了试验验证。最后结合未来工业互联网2.0应用以及未来6G的定位预期,阐述了北斗与5G通导融合、一体化的未来发展趋势。The fusion of communication and guidance is an important component and key direction in the development of integrated positioning,navigation and timing(PNT)system.The fusion algorithm of joint positio ning is studied based on the demand of PNT system and typical applications of users;two typical test scenarios are designed and constructed by using two PNT means,namely,indoor 5G signal positioning scenario and outdoor Beidou+5G joint positioning scenario.The experimental verification was carried out around the key index of positioning accuracy.Finally,the future development trend of the fusion and integration of Beidou and 5G is explained in the context of future industrial Internet 2.0 applications and future 6G positioning expectations.
