Chesapeake's SonarWiz Multibeam Server can now log raw IMU messages from connected motion sensors. This datalogging feature was developed in an effort to ease the workflow of surveyors using SBG Inertial Navigation Sensors (INS), but more specifically, users of SBG’s low SWAP Ellipse-N or Ellipse-D, which require an external datalogger if post-processing in SBG’s Qinertia PPK software is desired.

    The datalogger captures the full data stream, typically 200 Hz, and provides flexibility to process the data in Qinertia for high level data analysis and/or higher accuracy position and orientation, as needed after a survey.    Read more...


     EdgeTech, the leader in high resolution sonar imaging systems and underwater technology, has recently introduced an innovative and new method to provide nadir gap coverage on the EdgeTech 2205 sonar platforms.
     Complementing this new technology is SonarWiz from Chesapeake Technology, providing a software solution to support processing and mosaicking the new gap fill solution. 
    Harold Orlinsky, General Manager of Chesapeake, said “this data combination removes the digital seam seen at the sidescan nadir. SonarWiz makes a GeoTIFF image of the seafloor with the data set.”
EdgeTech Release  | Chesapeake Release

- Create a GeoTIFF from a Basemap to view mosaicked sonar imagery in SonarWiz or export easily.
- Use tools in SonarWiz to estimate survey duration and develop a set of survey lines at the same time.
- "Vertical" GeoTIFFs can encode elevation data or seafloor amplitude information.
- Chesapeake supports both EdgeTech 2205 and Klein MAX-View 600 Gap-Fill solutions. EdgeTech sees the nadir gap from both left and right. SonarWiz now imports and processes this extra data in CH5 & CH6. Read more...
- Overview of Support, Help Desk and Knowledge Base How To documentation.
- Winter training will be held December 13-16 at College of Charleston, SC, USA
