APPLICATION / HYDROGRAPHIC SURVEYING
Position, roll, pitch, heading and heave for vessel-based multibeam surveying: navigation inputs for georeferencing measurements and compensating for vessel motion.
Discuss your survey setupFIELD PHOTOGRAPH / RESERVOIR SURVEYTHE ROLE OF NAVIGATION
The IMU and dual GNSS antennas feed navigation processing. Its position and motion outputs support the survey equipment, alongside sonar, acquisition software and the geometry of the complete installation.
Illustrative data flow. RAYSEN provides the navigation system and related integration support; sonar, acquisition and survey processing remain parts of the wider measurement setup. Confirm message formats, output rates, interfaces and time synchronization for the connected equipment.
ASSESS YOUR SETUP
Use the measurement requirements and vessel conditions for a first fit assessment. Product and integration details carry the model-specific information.
Review the platform layout, GNSS visibility and installation geometry. The Jiujiang record shows one specific bridge-area measurement task.
Plan the equipment combination, calibration, acquisition and output review. The Bangkok record follows these steps in a harbour-basin demonstration.
Assess the onboard installation and operating conditions, including the vessel layout, sensor mounting and requirements of the survey task.
