中文摘要：
对于陆基无线电导航系统,为了得到最优的岸台分布算法,尽可能通过改善岸台分布提高工作区的定位精度,通过理论分析与仿真,详细研究与比较了双曲线定位和圆圆定位两种定位方式下的工作区某点GDOP值与岸台布局之间的关系,同时研究并对比了同一岸台布局下两种定位方式的定位精度分布,仿真结果表明双曲线定位方式要优于圆圆定位方式,并得到两者最佳的岸台分布方案。
英文摘要：
In order to find out a optimal station distribution algorithm and to improve positioning precision in working areas for wireless navigation system, the connections between the GDOP value and the station distribution are analyzed by the hyperbolic positioning mode as well as the range-range positioning mode respectively. Meanwhile, the positioning precision distributions for the two different positioning modes are compared in a condition of same station distribution. The simulation results show that hyperbolic positioning mode is better than range-range positioning mode. The optimal station distribution schemes for the two modes are obtained.
