摘要
提出了一种双频带混合GPS/Galileo接收系统,GPS与Galileo共同运作,规避了单一模式的安全漏洞,使卫星定位提供更稳定、更可靠、更安全的导航服务成为可能.接收系统同时接收GPSL1/L2和Galileo E1/E5a信号,提高了系统灵敏度,可以实现高精度定位和实时导航定位,同时能够最大限度地复用射频硬件资源,大大减少了芯片面积的消耗和系统功耗.通过系统参数仿真,各系统性能指标均满足设计要求.
This paper points out a dual-band hybrid GPS/Galileo receiver system. GPS is inter-operable with Galileo, avoiding the vulnerabilities of a single infrastructure and making the possibility of making satellite navigation services more robust, more reliable and safer. It can receive GPS＇s L1/L2 and Galileo＇s E1/E5a signals at the same time. The receiver improves system sensitivity, makes high accuracy and real-time navigation location, can maximize RE resources reuse and minimize chip size and system power consumption. As the simulation results indicated, every system speciation meets the requirements.
