Gyro kompass
Gyrokompass er et navigasjonsinstrument som viser riktige geografiske himmelretninger uten noen form for magnetisk misvisning slik magnetkompassene gjør (se kompass). Gyrokompasset retter seg altså inn mot den geografiske nordpolen, og kan dermed vise «rettvisende» kurser under navigering, uten noen form for magnetisk påvirkning fra skipets eller Jordens magnetfelt. Det klassiske gyrokompasset er basert på et gyroskop som er modifisert slik at aksen retter seg mot nord etter hvert som det påvirkes av jordrotasjon. Aksen i gyroskopet er da i praksis aksen i en elektromotor.
Typer
Selv om de fleste gyrokompass er basert på forskjellige former for gyroskop finnes det også nå nyere former som avviker fra dette, men likevel oftest kalles gyrokompass. Vi skiller derfor mellom forskjellige former for gyrokompass, etter hvilke grunnleggende sensorteknologi som benyttes:
-
mekaniske gyrokompass
-
optiske gyrokompass
-
«Solid State» gyrokompass
