NAVS-1000
Compact Navigator
Underwater Integrated Navigation Systems（IMU/DVL/DEPTH）
The NAVS-1000 is a new-generation all-in-one integrated navigation system, integrating a pressure sensor, Doppler Velocity Log (DVL), and high-performance inertial measurement unit (IMU). Designed specifically for compact Autonomous Underwater Vehicles (AUVs) and Remotely Operated Vehicles (ROVs), it is factory-calibrated and ready-to-use, eliminating the need for on-site calibration or secondary integration. The system directly outputs attitude, position, velocity, and depth data for immediate deployment.
To ensure reliable operation in ferromagnetic environments, the device does not incorporate magnetic sensors. Instead, it achieves self-alignment through north-seeking using the Earth’s rotational angular velocity, maintaining long-term heading stability. It comes standard with a 1000m-rated titanium alloy pressure housing. The INS/DVL system is pre-calibrated via shipboard testing, requiring no additional in-field calibration. The integrated pressure sensor delivers depth accuracy of 0.1 m and resolution of 0.5 mm, matching the performance of high-end standalone pressure gauges. Supporting integration with GPS and Ultra-Short Baseline (USBL) systems, the unit requires no waterproof modification and can be directly deployed for underwater navigation on AUVs/ROVs. It has been field-proven in multiple deep-sea operations with AUVs in the South China Sea and Eastern Pacific Ocean.
The NAVS-1000 employs an enhanced IMU design and advanced data fusion algorithms, significantly improving attitude and heading accuracy. Despite its compact dimensions of Φ101mm × 148mm, it delivers performance comparable to large-format fiber-optic gyroscope systems. When coupled with the DVL, the straight-line navigation accuracy reaches 0.5% of the distance traveled.
