Integrated Sensor Data Acquisition and Real-Time Processing

NaviPac excels in synchronizing and processing data streams from multiple sophisticated marine sensors simultaneously. Its robust integration capabilities cover:

Multibeam echosounders for detailed seabed topography.
Side-scan sonar for imaging the seabed surface.
Sub-bottom profilers for analyzing subsurface geological structures.
Ultra-short baseline (USBL) and Long baseline (LBL) positioning systems for accurate underwater object tracking.
Inertial navigation systems (INS) for precise vessel motion and orientation data.

This comprehensive sensor fusion ensures that all incoming data is time-stamped and georeferenced, providing a unified and accurate view of the subsea environment critical for detailed mapping and analysis.

Advanced Navigation and Vessel Control Features

The software provides essential real-time vessel positioning and guidance systems to maintain precise survey lines, even in challenging sea conditions. It features an integrated autopilot interface that allows for direct control of the survey vessel’s steering. This guidance system ensures that the vessel follows predefined survey routes with high accuracy, minimizing overlap and gaps in data acquisition and thereby enhancing the overall quality and efficiency of offshore survey operations.

Seabed Mapping, Modeling, and Georeferenced Data Visualization

EIVA NaviPac processes incoming bathymetric data in real-time, enabling immediate visualization of the seabed. A key capability is the generation of Digital Terrain Models (DTMs), which create detailed representations of the underwater topography. The software offers advanced visualization tools that allow users to explore and analyze both the seabed surface and sub-seabed structures, facilitating informed decision-making during marine engineering and surveying projects.

ROV and AUV Mission Planning and Monitoring Integration

The platform includes specialized modules designed for the planning, control, and post-mission analysis of Remotely Operated Vehicle (ROV) and Autonomous Underwater Vehicle (AUV) operations. NaviPac synchronizes data from the vehicle’s onboard sensors with the surface navigation data. This ensures coherent data sets and allows for precise mission execution and detailed review of underwater activities, crucial for complex tasks like underwater inspection or scientific exploration.

Specialized Tools for Pipeline and Cable Route Surveying

EIVA NaviPac offers dedicated features engineered for the meticulous planning and execution of surveys focused on subsea pipelines and communication or power cables. The software incorporates inspection tools that aid in identifying critical features such as pipeline free-spans and assessing the depth of burial. These functionalities are vital for ensuring the integrity and safety of subsea infrastructure.

Reporting, Data Export, and Workflow Optimization in Version 4.11.0

Version 4.13 of EIVA NaviPac introduces several enhancements aimed at optimizing user workflows and improving data management. Key updates include expanded support for the latest sensor models, refined data processing algorithms for tasks like tide correction and outlier filtering, and a modernized tab-based user interface that streamlines operations.
