In modern maritime operations, marine-grade Inertial Navigation Systems (INS), strapdown inertial navigation, and FOG/RLG inertial navigation systems have become core technologies for ensuring high precision, reliability, and continuity. This is especially critical in harsh sea conditions, remote ocean areas, and environments where GNSS signals are limited or unavailable.
Issues such as coastal signal blockage, multipath effects, and interference frequently occur, making sole reliance on GNSS inadequate. To ensure safe and stable vessel operations, an autonomous navigation reference is essential. Marine-grade INS delivers continuous navigation and attitude information completely independent of external signals, maintaining stable outputs even during GNSS outages.
Our marine-grade strapdown inertial navigation system incorporates advanced RLG ring laser gyroscopes or FOG fiber optic gyroscopes, paired with high-precision quartz accelerometers, enabling real-time accurate measurement of heading, roll, pitch, yaw, and vessel motion. Designed specifically for demanding marine environments, the system supports long-term continuous operation under vibration, temperature fluctuations, and high humidity.
Supporting pure inertial, GNSS-aided, and velocity-aided modes, it seamlessly integrates with gyrocompasses, speed logs, and other instruments to enhance the redundancy and continuity of integrated navigation systems, making it ideal for coastal waters, narrow channels, and open-ocean operations.
Marine-grade INS is widely applied in dynamic positioning (DP) vessels, offshore platforms, hydrographic survey ships, and unmanned surface vessels (USVs).
In real-world applications, high-performance FOG/RLG inertial navigation systems have proven invaluable. For example, in harsh North Sea conditions, they integrate with Doppler velocity logs to enable dynamic positioning vessels to maintain precise station-keeping; on hydrographic survey ships, combined with multibeam sonar, they ensure high-precision seabed mapping even during GNSS interruptions; and in USV pipeline inspections and port surveys, they provide autonomous navigation in GNSS-denied environments near offshore structures, significantly improving efficiency and reducing risks.
