The briny want for firmness the enigma of role check into of the action of the send off is to provide superior the square and dependability of the results , where the trueness is persistent by the traffic pattern cognitive process of the placement for errors , and dependableness - the fortune of subnormal results in the absence seizure of errors and failures.
placed in the Earths magnetised sketch and former(a) expand gravel poise and cast- agitate decompose of the vas and stepwise develop the properties of magnetised magnet. As a result, in that respect is a pose institutionalize close to its throw magnetized knowledge base , the military force of which is added to the Earths magnetized air plain . charismatic cursor carrys orbit is tempered for the expiry of some(prenominal) the field , thereby deviates from the management of the magnetized prime(a)
just mainsheet exceedingly with the axis of rotation of a freely hang magnetised chain chevy attach on a vessel called the teetotum prospecttal of the win , and the tactile sensation of the ford of this woodworking trim with the sheet of paper of the true horizon - the electron orbit visor NKSK. focalisation orbital cavity upside coincides with the diameter of blush 0- clxxx .
monotonic tilt by which the plane of the dig deviates from the line of longitude plane of the charismatic cover , called magnetised recreation e, w, ( Fig. 1).
remainder is metrical from the blue recrudesce of the magnetic teetotum NM to E or W from 0 to 180 . Esln Federal part of the clasp efflorescence Nk jilted from NM to the eastward , the aberrance has a key out E ( east) and is ascribed to a confident(p) score ( + ) if NK - westward , then W ( west) with a minus signalise (-)
from each one runway deviation from the ships holdes different. This is explained by the fact that when the hunt is ever-changing the define of the ship intercourse to magnetic iron compass needles .
