| Abstract: | This paper describes some engineering designing problems of the miniature sized inertial navigation system and designs a miniature sized strap-down inertial navigation system use micro electronic mechanical system inertial measurement unit (MEMS-IMU) as the inertial sensors, and the digital signal processors (DSP) as the kernel of the navigation computer. The hardware architecture and the software flow chart are offered, and then some problems of the designing and debugging DSP programs are discussed. It will be much advantaged to miniaturize the inertial navigation system in the military and technical field so as to reduce the system cost and size. |
