The Research Of Digital Compass Repeater

Since the compass appear in the navigational positioning plays a crucial role in the development of modern electronic technology has driven development of ship technology, navigation apparatus also tends to be more digital, intelligent, integrated development, which called for the shipheading information for multi-point repeat display.Electrical compass repeater function is multipoint repetitive display come from master gyrocompass position signal,with synchronization system together completed ship multiple sites to provide rapid heading information function.Using micro control unit for the stepper-motor subdivision and acceleration deceleration control, to realize the digital signal input of the compass repeater system principle, structure and the hardware and software design of the stepping motor, without accumulated error makes the compass repeater with high precision, but also solves the traditional compass repeater zero input jitter problem dial type display structure, also make up the digital display does not accord with people’s habits of observation.
