8. Gyro Applications
Shipboard Use - two gyros placed
deep in the ship on the centerline.
Primary- (Master gyro) oriented
to north/south, used for
navigation & shiphandling.
Auxiliary- (Back up gyro) oriented
east/west, used for combat
systems.

9. Gyro Applications
Bridge - gyro repeaters are located
on the bridge wings, navigation
table, captain’s chair & center line
which is referred to as “centerline
pelorus.”
CIC - Command and Control
System.
Weapons - gyro inputs (i.e..
pitch/roll), are used by fire control
computers

11. Gyro Error in Navigation
Causes of Error
•Friction
•Ship’s Motion
•Electronic Malfunctions
•Power Fluctuations.
A gyro compass is an electronic/mechanical
device with inherent error…. the key is
knowing the error and adjusting for it
