| Abstract: | The full status north positioning equipment is described in this paper, in which a dynamic tuned gyro and an accelerometer are applied as the measuring device. To improve the precision and speed for computing result of the system, a floating chip TMS320C32 digital signal processor is applied to compute and control, so that the bearing angle of true north can be automatically measured rapidly and precisely. The principles of dynamic tuned gyro north positioning equipment based on digital signal processor, signal processing, error analysis and performance comparing to other north positioning equipment are mainly discussed in the paper. |
