Abstract:

TMBOC modulation signal is used in GPS L1 frequency band,which has the advantages of compatibility and interoperability.In this paper,the modulation technique about TMBOC and the features of modulation signal are introduced.Then on the basis of theoretical analysis,a method for generating the modulation signal in a single FPGA chip is presented and the simulation waveform is given.The results show the feasibility of the method.

Key words: GPS;TMBOC;modulation;FPGA
