Not only U.S. GPS modernization, But also Russian GLONASS, the EU’s Galileo Project, and China Compass are planning or proceeding in accordance with the explosive growth in the use of location-based services nowadays.
In order to mitigate the interference effect caused by the same center frequency which Galileo E1 band and GPS L1’s, the E1 band exploits CBOC(Composite-BOC) Modulation technique which is one of the BOC(Binary Offset Carrier) modulation method. E1 band provides two Service named PRS(Public Regurated Service) and OS(Open Service). E1 OS Signal has two channel. data channel E1-B and pilot channel E1-C. The pilot channel contains no data.
This paper starts with designing the hybrid integration scheme for weak signal from E1-B and E1-C channel. Each channel has different characteristics to one another. Using modified SNR worksheet for Galileo E1 OS, the sensitivity of the receiver is analysed. And that result is verified by computer simulation.
