Abstract

New signal modulation design for next-generation of global navigation satellite systems (GNSS) must offer improved performance and the opportunity for spectrum compatible with existing and planned signals. This paper proposes a class of particularly attractive modulations called Minimum Shift Keying - Binary Coded Symbol (MSK-BCS) modulations, and demonstrates their essential characteristics and performance for GNSS. The principle of MSK modulation is first described. Then, based on the BCS modulations technique, the general mathematical model of MSK-BCS modulations is described. The MSK-BCS modulations present important characteristics for GNSS and provide superior performance with regards to noise, interference and multipath when compared to other BCS modulations. MSK-BCS modulations can provide potential opportunities for GNSS modernization and construction, such as Galileo, Compass, and so on.
