Abstract :
Playing an important role in navigation test, radio navigation generator is widely used in the people/military plane. But traditional equipment composed of analog circuit presents low accuracy and poor reliability. A new kind of digital navigation signal generator is designed in this paper. It receives data and commands from PC by MicroBlaze embedded soft processor of Xilinx company and demodulates information to control FPGA load different softwares to generate various navigation signals, which fully meets general radio navigation system test technical requirements by giving full play to the system hardware and software advantages and fulfilling design targets such as the accuracy, flexibility and expansibility. Therefore, providing a new idea for radio navigation system design and test, this generator can be widely applied to debugging use on people/military plane radio navigation.
