Underwater positioning system and method for an underwater tracked vehicle on the quay wall

摘要

The present invention provides real-time pinpoint the location of a moving exploration unit for performing research on coastal wharf in water to be related to the underwater location estimation system and method of the track-type underwater moving objects , according to the present invention , a conventional position tracking method using ultrasonic waves is in the range of error large , also , the current GPS systems , the target is located in the water, to solve the problem that it is not applicable , also with respect to the target on the basis of the water in the DGPS system more accurate position measurement that can track objects moving in water compared to a conventional type method underwater location estimation system and method are provided . ;
