The gyroscopic compass may have one or more gyroscopes. It is usually located as nearly at the rolling axis of the ship as possible and in a protected place. The directive force of a gyroscope, while 100 times more powerful than that of the magnetic needle, is still further amplified by an auxiliary electric motor sufficiently powerful to operate the compass card in azimuth. Repeater compasses, installed wherever desired about the ship, are operated by the master compass containing the gyroscopes by a simple electric follow-up system. The gyroscopic compass is not affected by magnetism from any source. It points to the true north, not the magnetic pole, and hence required no calculations for corrections. It is not affected by cargo or any type of magnetic field which may surround it and it is not disturbed by jars. It has become standard equipment in navies and is coming into more general use on commercial vessels.
Ikhampasi yevili elijikeleza lizinzise inqanawe inokuba nevili elinye nangaphezulu la mavili ajikeleza azinzise inqanawe. Yakhelwe kufuphi ne-'rooling axis' yenqanawe, kwindawo ekhuselekileyo. Isixhobo esisemgangathweni kwinqanawe kwaye iya isetyenziswa ngokuthe gabalala kwiinqanawe zorhwebo.
