Gyrocompass · Position & Heading
Safran Sigma 40 Fiber Optic Gyro — Position & Heading. As a Gyrocompass, it is normally installed on the bridge with the required external sensors, antennas, displays and data-network interfaces. In that role, its primary purpose is to provide navigation, position, heading, speed, depth, traffic or bridge-management information according to the listed category. Radar, ECDIS, gyrocompass, GNSS, speed log, echo sounder and integrated bridge systems use different sensing principles, so calibration and interfaces must match the actual installed equipment. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
What our service work and the manufacturer documentation say about keeping this model running.
Inspect sensors, antennas, transducers, cabling, power supplies, displays and data interfaces. Compare information with independent references and review alarm history. Verify distribution to dependent bridge systems and confirm approved backup arrangements. Refer to the manufacturer documentation for the exact figure for calibration, alignment and performance criteria.
Carry fuses, interface cables, approved power supplies, sensor or antenna parts and supported display or processor modules, together with backed-up configuration data where applicable.
