EIVA NaviEdit 9.1

EIVA NaviEdit 9.1

EIVA NaviEdit is a powerful navigation and sensor data editor that forms a key part of the EIVA NaviSuite marine survey software ecosystem. It is used to import, visualize, filter, and correct data streams from a wide range of survey sensors, including multibeam echosounders, side-scan sonar, sub-bottom profilers, and positioning systems (GNSS, USBL, LBL). The software focuses on removing outliers, applying time delays, smoothing trajectories, and merging data from multiple sources to create a clean, synchronized dataset ready for final processing and charting in tools like NaviModel or NaviScan.

🚢 Primary Users

EIVA NaviEdit 9.1.0 is a specialized data editing and processing software designed for Hydrographic Surveyors, Geophysical Data Processors, Offshore Survey Engineers, ROV Data Specialists, and Marine Technicians who need to clean, correct, visualize, and quality control raw navigation and sensor data from marine survey operations before final mapping and reporting.

✨ Key Features & Capabilities

• Multi-Sensor Data Visualization & Synchronization: Simultaneously displays time-series data from multiple sensors (position, heading, depth, heave, etc.) on a synchronized timeline for identifying and correcting misalignments.

• Advanced Data Filtering & Cleaning: Tools for manual and automatic filtering of outliers (spikes) in navigation and attitude data, and for smoothing noisy datasets.

• Time Delay & Lever Arm Calibration: Precisely calculate and apply time delays between sensor clocks and correct for physical offsets (lever arms) between sensors on the survey platform.

• Trajectory Reconstruction & Editing: Reconstruct and edit vessel/vehicle trajectories using a combination of positioning sources, especially important when primary GPS data is lost or degraded.

• Data Export & Integration: Exports cleaned and corrected navigation data in standard formats (e.g., ASCII, EIVA’s .nvi format) for seamless import into other EIVA processing modules or third-party software.

• Quality Control & Reporting: Provides statistical analysis and QC plots of processed data to verify accuracy and generate quality control reports.

🆕 What’s New in Version 9.1.0

This update focuses on enhanced performance, modernized workflows, and improved handling of modern sensor data.

• Enhanced User Interface & Performance: A more responsive interface and faster loading/processing of extremely large datasets from modern high-resolution surveys.

• Improved GNSS/INS Post-Processing Integration: Tighter workflow with EIVA’s NaviPac for integrating post-processed inertial navigation solutions (POSPac, Inertial Explorer) into the editing workflow.

• Expanded Sensor Format Support: Added native support for newer models of multibeam sonars, INS systems, and other marine sensors.

• Advanced Filtering Algorithms: New and improved algorithms for automatic spike detection and data smoothing.

• Streamlined Project Management: Better tools for managing and batch-processing multiple survey lines or data files within a single project.

💻 System Requirements

• OS: 64-bit Windows 10/11 Professional.

• CPU: Multi-core Intel i7/Xeon or AMD equivalent.

• RAM: 16 GB minimum (32 GB+ recommended for large datasets).

• Storage: Fast SSD (NVMe recommended) with high capacity for raw and processed data files.

• Graphics: Professional graphics card (NVIDIA Quadro or AMD equivalent) with 2GB+ VRAM recommended for smooth visualization of complex data.
