| 摘 要： | 在全球各大卫星导航系统的导航信号中,E1/L1频段最为拥挤,也是系统间兼容性和互操作性研究的重点,其中Galileo试验星GIOVE-A率先发射了采用BOC调制方式的民用信号。该文研究并设计实现了完整的Galileo软件接收机。该接收机成功捕获、跟踪和解调了GIOVE-A信号,并得到了正确的定位结果。测试结果表明,在相同的模拟器配置和接收机参数下,其测距精度和定位精度均优于GPSL1C/A码接收机。

| Abstract: | Among all the navigation signals by the major satellite navigation systems worldwide,E1/L1 band is the most crowded one,which makes it the key point of inter-system compatibility and interoperability study.Galileo test satellite ＂GIOVE-A＂ is the first one transmitting civilian signals using BOC modulation.This paper focuses on design and implementation of Galileo E1B Software Receiver.This receiver can successfully acquire,track and demodulate GIOVE-A signals.The test results demonstrate that its accuracy of pseudorange measurement and position solution is better than the GPS L1 C/A receiver under the same configuration of simulator and receiver. |
