| 摘 要： | 目前互操作已经成为世界各主要卫星导航系统关注和研究的重要问题,北斗作为重要GNSS系统之一,也在研究互操作的有关问题.GPS和Galileo利用在中心频率为1575.42MHz的L1/E1频段上分别调制TMBOC和CBOC信号,实现了两个系统间的互操作.我们给出了互操作的概念,分析了互操作的需求,利用卫星轨道数据验证了系统间互操作可有效增加接收机可视卫星数目,改善DOP值.利用码跟踪误差和多径包络曲线分析了GPS和Galileo互操作信号性能,最后初步探讨了北斗与GPS,Galileo进行互操作的方式.

| Abstract: | Interoperability is a hot issue among all satellite navigation systems, which is the important approach for BeiDou to be global. GPS and Galileo have firstly finished the design of interoperability in L1 and E1 band, where the TMBOC and CBOC are designed respectively, with the carrier frequency 1575.42 MHz. In this paper, the definition of interoperability is given; a detailed requirement analysis for interoperability is illuminated. The contribution of interoperability that more satellites can be chosen by... |
