远程无线电导航系统的定位误差分析及其仿真

Analysis and simulation of the positioning error inremote radio navigation system

针对无线电导航系统定位的原理 ,根据双曲线定位的特点详细地推导了径向定位误差 ,并且分析了几何精度因子对定位精度的影响 .最后仿真了不同台址的分布随着经、纬度和距离的变化 。

Aiming at the radio navigation system positioning principle,we calculated the radial positioning error by hyperbola positioning trait.We analyzed the effect of Geometrical Dilution of Precision on the positioning precision.we simulated GDOP solid figures and equal precision plane figures by longitude and latitude and distance with different radio launch pads.
