Digital Signal Processor In The Navigation System

The dissertation mainly studies the application of digital signal processor (DSP) to navigation system of some marque armed helicopter, and presents the software' s and hardware' s implementation of the main board (DSP board), and the theory above is used in navigation system' s practical operation and control.At the beginning, the paper introduces the current situation of navigation system of armed helicopter and characteristic of digital signal processor, explains why application DSP to navigation system of armed helicopter, then emphatically introduces the software' s and hardware' s implementation of the DSP board .The paper specially emphatically introduces the navigation software, in the course ,we can get a conclution that because of DSP' S sustentation of advanced language, and modularized programming idea, which make the whole navigation program' s development easy, the period of development shorten greatly, readability boosted enormously, extensibility and maintainability improved highly.Since the whole navigation program is very huge, and flight precision is not only rests on sensitive sensor but also rests on the correctly running of navigation program, so the software' s test(mainly point the reliability' s test) is very important and be introduced at the last in the paper , the program' s correctness is tested by emluator. ( make use of the idea of virtual instrument, implemented by the LABVIEW programming lauguage)...
