摘　　要：针对多天线技术在全球卫星导航系统(GNSS)组合声学测距应用中存在解算效率不高的问题,提出多天线GNSS/声学组合定位模型和虚拟天线GNSS/声学组合定位模型:采用精准化天线位置的方式实现高效率解算;然后通过水下定位仿真实验,对比分析虚拟天线定位模型与多天线定位模型。结果表明,在海底定位精度方面,虚拟天线定位模型与多天线定位模型相近,多天线定位模型及虚拟天线定位模型优于传统单天线定位模型;在解算效率方面,虚拟天线定位模型优于多天线定位模型,虚拟天线定位模型处理耗时180.020 s,多天线定位模型处理耗时50.257 s,解算效率提升约3.6倍。Aiming at the problem of low solution efficiency of multi-antenna technology in the application of global navigation satellite system(GNSS)combined acoustic ranging,the paper proposed a multi-antenna GNSS/acoustic combined positioning model and a virtual antenna GNSS/acoustic combined positioning model:the precise antenna position was adopted to achieve high-efficiency solution;and then through underwater positioning simulation experiments,the virtual antenna positioning model and the multi-antenna positioning model were compared and analyzed.Result showed that in terms of seafloor positioning accuracy,the virtual antenna positioning model would be similar to the multi-antenna positioning model,and the multi-antenna positioning model and the virtual antenna positioning model could be better than the traditional single-antenna positioning model;meanwhile,in terms of solution efficiency,the virtual antenna positioning model would be superior to the multi-antenna positioning model,the virtual antenna positioning model would take 180.020 s for processing,and the multi-antenna positioning model 50.257 s,indicating that the solution efficiency could be improved by about 3.6 times.
