Abstract
The research on satellite navigation signal is one of the most essential topics in satellite navigation system. The enhancement of the signal will undoubtedly improve the service quality of navigation system. Dealing with this problem, applying latest emerging coding schemes have been proved to be efficient. Therefore, we analyze the application of fountain code into satellite navigation system in this paper. To achieve better transmission, we first propose a modified encoding algorithm to reduce the minimized transmission packets cost. Further, by introducing Low-Earth orbit satellite, we concatenate digital fountain code with traditional channel code. By doing so, we can optimize the utilization of fountain code in satellite channels. Finally, simulation results are conducted to valid our theoretical analysis.
