Abstract
Introduces the modulate mode of signals in GNSS signal simulator. The principle of wide frequency modulate and its implementation method in GPS and GLONASS are described. The generation method of pseudo-random code and wide frequency modulated signals of GPS and GLONASS in GNSS signal modulator is established. With the Xilinx’ISE11.2 and ModelSim6.5 development tools and FPGA using verilog,the design and simulation of wide frequency modulates is implemented,and the emulator wave and signal frequency spectrum are given. The wide frequency modulate module has been in application in one prototype of GNSS simulator model. By the procedure simulating and system testing,it is shown that the module specifications of the wide frequency modulate module meet the requirement of GNSS signal simulator.关键词
