| 摘 要： | 伪卫星是基于非星基平台提供附加导航信号的设备,可与现有导航卫星共同工作或独立工作,能有效地改善导航性能。当伪卫星独立工作时,其空间分布对导航定位性能和应用有很大影响。针对基于中高空飞行器平台伪卫星网络的定位特点,提出一种高/低空混合蜂窝构型,并对可见性、远近效应和精度因子(DOP)分布进行了仿真。仿真结果表明,蜂窝构型具有覆盖范围大、拓展方便和DOP好的优点,能够提高覆盖地域的定位性能。

| Abstract: | Pseudolite offers additional navigation signal based on non-satellite platform,working with existing navigation satellite system or alone,can effectively improve navigation performance. The geometric distribution of pseudolites produces great effect on posi- tioning performance and application. Considering the characters of pseudolite network based on medium/high altitude aircraft,the paper gives a high/low attitude honeycomb distribution and simulation results of visibility,near-far effect and dilution of precision（DOP）. The results show that the honeycomb distribution network has advantages of great coverage area,easy extension and low DOP,which can im- prove the positioning performance in the navigation service area. |
