: Speed and latitude are manually entered via the operator unit and transferred to all connected gyro compasses. It is obligatory to input actual speed and latitude data to ensure correct speed error calculation, including the correct north/south indication.

Because a gyro compass is subject to errors induced by the Earth's rotation and the vessel's velocity, corrections must be applied either automatically via interface inputs or manually at the control panel:
Check the fluid levels and the condition of the supporting liquid. Severe vessel movement during startup
Use twisted, shielded pairs for NMEA 0183 data lines to avoid signal interference.
Inspect the mechanical gimbals, dampening fluid (if applicable), and physical cables to ensure the compass can swing freely during heavy vessel motion. Inspect the mechanical gimbals
This housing provides the electrical contacts, heating elements, and cooling channels necessary to maintain the supporting fluid at a constant operating temperature. The Follow-Up System
