How is a ship guided by a compass in navigation
Asked such a professional problem does not give points....Compass is a concept, I do not understand.. Professional point of view: the ship is sailing on the compass, the ship is equipped with magnetic compass and gyro compass two kinds, of which the accuracy of the gyro compass is very high, so the ship is basically connected to some of the compass signal on the navigation aidsTo correct an error, the compass can not navigate, compass is only a navigation aid, at present, all basic marine navigation equipment is GPS
According to the number of degrees on the ship the ship can maintain a degree of value without changing the straight line navigation not to trek
I also do the workbook, fuck, no one answer, do so swollen
