Application of TMS320C6748 DSP in strapdown inertial navigation system based on MEMS

Strapdown inertial navigation system based on MEMS was applied more and more widely in engineering, and traditional processors have been increasingly unable to meet the accuracy, real-time requirements. Therefore, to improve the calculation accuracy of strapdown inertial navigation system based on MEMS is one of direction of the scholars research. A MEMS strapdown inertial navigation system based on TMS320C6748DSP, which is TI´s latest developed products, was designed in this paper. Four modules were designed in this system: power management module, the data receiving module, data solver module, data storage and transmission module. Design of the hardware and software about this system and the part of software program also were given. The performance comparative test between C6748 and C2812 were done. Simulation results show that this system based on C6748 has better high-precision, and real-time, and it can meet the performance demand.
