| Abstract： | In view of the increasing demand trend of timeliness, reliabitity and operating convenience of dynamic mapping technology for mobile carrier attitude information, combined with the latest developments of inertial technology, position data acquisition, processing and display system based on the Mti-g micro inertial navigation were designed. Using the MSComm control which belongs to microsoft foundation classes (MFC) serial communication real-time technology, real-time data acquisition of the Mti-g data is completed. The quaternion method is adopted to update the strapdown inertial navigation system matrix in order to complete the calculation of carrier attitude angle. By taking advantage of open graphics library (OPENGL) graphics editor technology, two-dimensional real-time curve, the three dimensional dynamic display function of the carrier attitude algorithm of data are obtained. Finally the software design is validated with experiment results of reasonable feasibility. |
