METHOD FOR DETERMINING OF TRAWL MOTION PARAMETERS AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2006 - IPC A01K71/00 A01K73/00 A01K74/00 

FIELD: commercial navigation and fishery effectuated by means of pulled catching facilities, preferably rear sweeping trawls.

SUBSTANCE: method involves providing additional signals according to deviation angles of right-hand and left-hand wires relative to diametrical plane of puller vessel and also signals according to angles of submersion of right-hand and left-hand wires into water relative to waterline plane of puller vessel, from which signals trawl motion parameter signals and puller vessel motion parameter signals are determined. Apparatus has right-hand and left-hand converters for converting angles of wire deviation from diametrical plane of puller vessel and also for converting angles of submersion of wires into water relative to waterline plane of puller vessel, with outputs thereof being outputs of apparatus by trawl motion parameters and puller vessel motion parameters.

EFFECT: wider operational capabilities, in particular, provision for determining commercial courses and reliable and precise evaluation of trawl motion parameters and puller vessel motion parameters, and automatic and continuous controlling of motion and operation of trawl.
