EIVA NaviScan 9.10.0 is a specialized, real-time data acquisition and processing software module within the EIVA NaviSuite, dedicated to geophysical sensors used in offshore surveys. It is the primary tool for operators managing sidescan sonar (SSS), sub-bottom profiler (SBP), and magnetometer systems. NaviScan provides a streamlined interface to control these sensors, monitor data quality as it streams in, perform essential corrections, and make on-the-fly interpretations—all while the survey vessel is on line. This immediate feedback loop is critical for ensuring data completeness, identifying targets of interest, and making go/no-go decisions during expensive offshore operations.

(H2) Core Functional Capabilities of NaviScan 9.10.0

• Integrated Real-time Data Acquisition & Display
  Control multiple geophysical sensors from a single interface. The software displays live, waterfall-style images for sidescan sonar (port and starboard channels) and sub-bottom profiler data, allowing the operator to instantly assess bottom texture, identify objects, and view sub-seafloor layers as they are collected.

• On-the-Fly Data Processing & Corrections
  Apply essential processing in real time to improve data clarity. Features include time-varying gain (TVG) for sidescan, tide correction, layback (sensor position) calculation, and basic filtering. This delivers a cleaned and geographically positioned data stream ready for preliminary interpretation while still on site.

• Target Logging & Annotation Tools
  Document findings immediately during the survey. When an anomaly (e.g., a wreck, pipeline, or UXO) is detected, the operator can log it directly on the sonar image, assigning a position, category, and comments. These logs form the basis for preliminary reports and guide follow-up investigations.

• Seamless Integration with Navigation & Other NaviSuite Modules
  Work within a unified survey ecosystem. NaviScan is fully integrated with NaviPac for precise vessel positioning and NaviEdit for planned line following. Acquired data and logs are seamlessly passed to post-processing modules like NaviModel for detailed analysis and report generation, ensuring a continuous digital workflow.

(H2) The NaviScan Advantage in Geophysical Surveying

The value of geophysical data is often time-sensitive; discovering a data gap or system fault days after a vessel has left the site is a costly failure. EIVA NaviScan 9.10.0 addresses this by putting powerful quality control and interpretation tools in the hands of the surveyor during acquisition. Its role-based interface allows sensor specialists to focus on data integrity and target detection, confident that all information is being logged, positioned, and stored correctly within the larger project database. For companies performing pipeline route surveys, UXO clearance, or seabed mapping, NaviScan is the critical real-time nerve center that turns raw acoustic signals into actionable intelligence.
