摘要

本文分析了在巴基斯坦海军舰艇上使用中国北斗作为卫星导航系统，作为目前使用最广泛的美国GPS的替代或额外援助。与GPS相比，全尺寸北斗的精度稀释系数较低，意味着在阿拉伯海的覆盖范围更好。并将北斗开放服务信号B1与常规GPS信号L1进行了比较。B1在多径误差和互相关噪声方面有更好的性能。最后，本文从射频前端、信号处理和计算导航解决方案等方面阐述了L1接收机接收B1信号的设计考虑。

Beidou: A GPS alternative for Pakistan's naval vessels

The paper presents analysis for using China based Beidou as satellite navigation system in Pakistan's naval vessels as an alternative or additional aid to US based GPS, which is currently most widely used system. A full scale Beidou will have lower dilution of precision implying better coverage in Arabian Sea as compared to GPS. The paper also compares Beidou open service signal B1 with conventional GPS signal L1. B1 has better performance in terms of multipath error and cross correlation noise. Lastly, design considerations for receiving B1 signal on L1 receiver are addressed in the paper in terms of modifications required in RF front end, signal processing and computing navigation solution.
