Sea Scan® ARC Explorer Software History

February 2014
Software Update:

    Features



    • .Added a new option for calculating the Sonar Depth to the Layback window. This method works with the 1st bottom return (Altitude) and a depth sounder (Total Water Depth). This can be used when the 1st surface return is not visible.

    Bug Fixes



    • RFixed a bug in the Marker Event window where a Waypoint would be reclassified as a Marker when the Waypoint Name and Description was modified.
    • Retargeted the trace.txt file go to C:\ root folder.
    • Retargeted the HDS driver logfile, "stu_sonar.log", to the C:\root folder.
    • Fixed the web link to the downloads since we have a new website. The link is now : http://www.marinesonic.com/support.html
    • Fixed a formatting problem when the time was being printed where the decimal seconds would have a leading zero.
    • Rewrote the SDS data stream time synchronization routine to better handle occasional timing issues with SYNC packets. This would cause sonar data to be dropped.

    Other



    • None.


August 2013
Software Update:

    Features



    • Rewrote the waterfall subsampling algorithm to be more flexible and faster.

    Bug Fixes



    • Rewrote the waterfall subsampling algorithm to handle different sample sizes for each channel.
    • Added a filter for the black lines in the ARC Explorer Sonar driver.

    Other



    • None.


July 2013
Software Update:
    Features

    • Added the option to set the Sonar Detect current in the arc_sonar.ini file.
    • Rewrote the NMEA Parser Latitude/Longitude parsing functions so that it is not bothered by non-standard Longitude GPS strings.
    Bug Fixes

    • Fixed a reduction in precision in the NMEA Manager that degraded the precision Latitude/Longitude positions from double precision to a single precision.
    Other
    • None.


June 2013
Software Update:

Features



  • None.

Bug Fixes



  • Fixed the projected swath did not get wider when changing ranges when layback NOT enabled.
  • Fixed the nav plotter takes WAY too long to display the swath.
  • Fixed support for the data flags in SNR2 SDS packets. Added support for older SNR1 packets.
  • Fixed delete event marker from the plotter window.
  • Fixed command line opening of files.

Other



  • None.


June 2013
Software Update:
    Features

    • None.

    Bug Fixes



    • The XTF converter would fail when converting surveys with no SONAR data in the first file.
    • The XTF converter would fail or crash when converting single files (not in a survey).
    • Navigation data was not being generated in the Simulated Sonar.
    • The projected swath in the navigation plotter was not being drawn.
    • The settings were not being applied when the OK button was clicked.
    • Improved the operation of the ARC Explorer Sonar driver power controls.
    • Fixed the tow cable disconnect warning in the ARC Explorer Sonar driver.
    • ARC_SONAR.INI file log file entry was misspelled.

    Other



    • None.


April 2013
Software Update:

    Features



    • Added Support for the Sea Scan ARC Explorer side scan SONAR system.
    • Added support for Layback events.
    • Chart plotter now auto re-centers when near the edge (not outside of the edge).
    • Marker and Layback events are now shown in the waterfall. Use the Show Data Events in the "Waterfall Features" settings.
    • Double clicking on a Marker Event shown in the waterfall shows the Marker Tooltip.
    • All printed time/dates reflect GMT time zone.
    • Improved the de-logging algorithm.
    • Waterfall Captures now support JPEG format. Report Waterfall Captures are in JPEG format.
    • Changed the new computer default window placement and default settings (most notably units to US units)
    • Application can be set to defaults see the Load Application Defaults button on the Application Settings page.
    • Added the Range & Bearing tool window. It will guide the user to the currently selected waypoint or marker event.
    • Waterfall can be moved 1 line at a time by using the arrow keys.
    • Registry settings can be ignored by holding the Left Shift key down while the application starts.
    • Added support for Magnetometers. Supports: Proton4, Sea Spy, G-880, G-866, and ASCII
    • The Status Window now shows Left/Right/Up/Down for sonar orientation in addition to +- degrees.
    • Application now has an "Advanced Mode" for troubleshooting.

    Bug Fixes



    • Fixed a bug in the NMEA input that caused Sea Scan Survey to incorrectly report the GPS accuracy for RTK GPS's. The fix provides a better estimate when using RTK GPS's with Sea Scan Survey.
