摘　　要：卫星信号天生脆弱,需要抗干扰能力较强的罗兰C台链作为无线电导航的备份手段,当前能否将圆圆定位技术广泛应用于陆基长波导航尚无定论。为探讨陆基长波导航系统中双曲线与圆圆两种定位模式的选取问题,结合我国现有罗兰C系统的分布情况,利用Matlab软件模拟仿真,分析比较了两种定位模式在岸台布局下的GDOP值,并以东海台链为例进行对比分析。仿真结果表明,在现有台链布局下,双曲线定位模式在绝大多数工作区域内GDOP值均优于圆圆定位模式。Satellite signals are inherently fragile,so Roland C chains with strong anti-jamming ability are needed as backup means of radio navigation.Whether circular positioning technology can be widely used in land-based long waveguide navigation is still uncertain.In order to discuss the selection of hyperbolic and circular positioning modes in land-based long waveguide navigation system,the GDOP values of the two positioning modes under the coastal platform layout are analyzed and compared by using Matlab software simulation,and the East China Sea platform chain is taken as an example.The simulation results show that the GDOP value of hyperbolic positioning mode is better than that of circular positioning mode in most working areas under the existing chain layout.
