Kongsberg C4 AUTO Product Specification
1. Product Overview
The Kongsberg C4 AUTO is an advanced marine autopilot system engineered for precise vessel control across commercial shipping, offshore support, and naval applications. As a core component of integrated bridge systems (IBS), it specializes in autonomous course keeping, track following, and dynamic positioning assistance—key to reducing crew workload, optimizing fuel efficiency (up to 5% savings), and ensuring navigation accuracy even in harsh sea conditions (strong winds, heavy swells, and current interference).
Equipped with adaptive control algorithms and real-time sensor data fusion (GNSS, gyrocompass, wind sensor), the system dynamically adjusts to vessel dynamics and environmental changes without manual intervention. It seamlessly integrates with Kongsberg’s K-Bridge IBS and complies with international maritime standards, making it a reliable solution for modern smart ships and offshore platforms.

3. Product Specifications & Features
3.1 Core Specifications
The C4 AUTO is optimized for versatile vessel control, covering a wide range of ship types from small coastal patrol boats to large offshore supply vessels. Its adaptive control system automatically adjusts gain parameters based on vessel speed, draft, and sea state, maintaining ≤±0.5° course keeping error even in rough conditions—eliminating the need for manual tuning.
Dual GNSS and high-precision gyrocompass integration ensures reliable positioning, critical for route-constrained areas (narrow channels, offshore wind farms). Redundant power and communication paths guarantee 99.99% operational availability, meeting IMO safety requirements for critical navigation tasks.
3.2 Key Features
-
Adaptive Control: Dynamically responds to wind, current, and vessel dynamics for consistent performance across all sea states.
-
Multi-Sensor Fusion: Combines GNSS, gyrocompass, and wind data to maintain accuracy in GNSS-challenged environments (near shorelines, tall structures).
-
Fuel Efficiency: Steady course keeping reduces unnecessary steering corrections, cutting fuel costs on long-haul voyages.
-
IBS Compatibility: Seamlessly connects with Kongsberg K-Bridge and third-party ECDIS for integrated situational awareness.
-
User-Friendly Design: 1U touchscreen panel with customizable shortcuts and real-time diagnostics for easy operation and maintenance.
