Abstract
The development of satellite navigation system and satellite communication system puts the research on the integration of satellite navigation and communication on agenda. However, a unified signal system cannot currently realize high precision positioning and high speed data transmission simultaneously in satellite navigation and communications integration. Therefore, a new integrated signal model for navigation and communication was proposed in this paper. This signal uses traditional navigation signal as pilot signals to realize synchronization, and Cyclic Code Shift Keying(CCSK) signals as communication signals to transfer data. Theoretical analysis and simulation show this signal improves the transmission rate of satellite data and has strong compatibility with Global Navigation Satellite System(GNSS). And the feasibility of the signal was verified through the hardware platform.
