Integrated Navigation System
Integrated deep-sea navigation system combining high-precision IMU and phased-array DVL for accurate positioning of ROVs/AUVs in depths from 3000m to 6000m.
The system offers three heading accuracy levels—0.1°, 0.2°, and 0.4°—and supports two DVL models (600 kHz and 300 kHz). Paired with a titanium alloy pressure-resistant housing, it delivers both precision and reliability.
Supports multi-sensor data fusion and international standard protocols. Achieves calibration in 5 minutes, compatible with dynamic/static base alignment for rapid deployment and plug-and-play operation. Fully empowers deep-sea scientific research and engineering applications.
- Integration of High-Precision IMU and Phased Array DVL
- Three heading accuracy options (0.1°/0.2°/0.4°)
- Titanium alloy pressure hull, 3000m–6000m deep-sea operations
- 5-minute quick calibration, plug and play
- Supports multi-sensor data coupling and international standard protocols
