Abstract
The compass repeaters of a gyro-compass are adjusted by a follow-up motor (1) in response to differential signals between the north-indicating gyro-system and a gyro-system enveloping bowl (18) which is connected to the compass card. In order to permit adjustment of the compass repeaters and a consistent verification of the relative positions of the master compass card and the compass repeater cards, an electronic control means (10) produces a pulse sequence for stepping motors which corresponds to the differential signals, the stepping motors (1) synchronously adjust the compass cards of master compass and compass repeaters, a sliding contact (11), comprising an interruption point (5), is in wiping contact with a brush (6), and an adjusting power supply (9) supplies a current to brush (6) for adjusting the compass cards, while the follow-up switch (7) is off, and until the interruption point (5) is contacted by the brush (6).
