Adjusting arrangement for compass repeaters

Adjusting arrangement for compass repeaters of a gyro-compass, comprising a follow-up motor (1) which effects the adjustment in dependence on differential signals between the north-indicating gyromagnetic compass and a bowl (18) enveloping the gyro-system, in which the gyro-system is supported in a manner known per se (e.g. by means of a fluid bearing) and is connected to the compass card, characterized by

• (a) electronic control means (10) which produces from said differential signals a corresponding pulse sequence for stepping motors,
• (b) substantially identically designed stepping motors (1 to 4) which in response to the pulse sequence produced by the electronic control means (10) synchronously adjust the compass cards of master compass and compass repeaters, wherein a reduction gear unit is preferably interposed therebetween,
• (c) a per se known sliding contact (11) connected to the compass card of the master compass, said sliding contact being in wiping contact with a brush (6) and including an interruption point (5),
• (d) an adjusting power supply (9) for supplying an adjusting current to the brush (6) so that, when the follow-up switch (7) is in the OFF state, the compass cards are adjusted via the stepping motors (1 to 4) of the master compass and the compass repeaters until the interruption point (5) is contacted by the brush (6).
