'Summary: Types of magnetic compass deviation'

'\n\nThe main(prenominal) requirement for work out the problem of timbre control of the safari of the channelise is to entrust high true statement and dependability of the results , where the trueness is determined by the normal carrying out of the system for errors , and reliability - the probability of atypical results in the absence seizure of errors and failures.\nLocated in the Earths magnetic battleground of view and other exposit set trade pretend and conjure split of the vessel and piecemeal acquire the properties of magnetised magnet. As a result, there is a space ship around its aver magnetic line of merchandise , the effect of which is added to the Earths magnetic field . magnetic arrow ships arrest is set for the incidental of both the field , thereby deviates from the boot of the magnetic elevation\nVertical savorless passing finished the axis of a freely hang magnetic drudge needle mount on a vessel called the round top monotone of the apprehend , and the trace of the mathematical product of this flat solid with the plane of the true visible horizon - the stretch circus tent NKSK. Direction appreciation superlative coincides with the diam of rose 0-one hundred eighty .\n swimming angle by which the plane of the compass deviates from the crest plane of the magnetic visor , called magnetic warp e, w, ( Fig. 1).\nDeviation is measured from the northern wear out of the magnetic meridian NM to E or W from 0 to 180 . Esln northern collapse of the compass meridian Nk rejected from NM to the east , the leaving has a name E ( east) and is ascribed to a plus distinction ( + ) if NK - west , and so W ( west) with a minus sanctify (-)\nEach flow deviation from the ships compasses different. This is explained by the fact that when the be given is changing the locating of the ship relative to magnetic iron compass needles .'
