| Abstract: | The data that MEMS Guidance Navigation and Control (MGNC) integrated electronic unit requires to collect and process is large and the algorithm is complicated. By using the technologies of pipelining and high-speed serial bus, a kind of integrated electronic unit with multi-channel, real-time, synchronal-sampling is completed. A reduced-order kalman filter is applied in the integrated navigation algorithm of GNC software and the dynamic car test result shows that the real-time and intellectual characteristics of navigation software are effectively improved by this kind of design method. And that also makes it possible to enhance GNC software running-speed and effectiveness ultimately. |
