HYDRINS, the hydrographic inertial navigation system which
interfaces notably with a multibeam sounder and GPS. It provides real-time,
high-accuracy and high-frequency position, heading and attitude data even in
case of GPS drop-out. |
| FEATURES |
• Integrates sensors, electronics and kalman filter in one housing
• GPS drop-out/multipath real-time management
• GPS height real-time management
• SAFE HEAVE filter |
| BENEFITS |
|
• All-in-one solution
• Less than 1 meter drift in 1 minute
• Prevents height artefacts
• No heave post-processing |
