  • Where can I download the latest version?

    The link to download the Delph INS version is

  • What is the minimun needed output frequency for the post processing protocol?

    The minimum output frequency is 50 Hz, but for survey application it's better to have the output at 100Hz or at 200Hz.

  • After launching Delph INS the message "No license detected" is displayed and the access to the common features of the software is disabled.

    This error message can be displayed in three situations :

    • After a re-installation of the software you need to unplug and then re-plug the dongle, otherwise the dongle is not recognized.
    • When the Sentinel driver (the dongle's driver) is not correctly installed. Delph INS installs automatically the driver but in different situation this default installation fails, in this case you need to download the Sentinel installation program from the SafeNet web site and install it manually (unplug the dongle before installing the driver).
    • When the version of the application you try to launch is too recent regarding the end warranty date hard coded into your dongle. You can display the content of your dongle using the License. command of the ? menu.
    • You can display the date of release of your current version using the About Delph INS. command from the ? menu. Contact iXblue if you want to upgrade your dongle. This installation has been tested using Mac OS X El Capitan (10.11.6) + Virtual Box 5.1.6 + Windows 7 SP1 + Delph INS Subsea 3.0.1.
  • Is it possible to run Delph INS on Mac OS

    Delph INS is only running on Windows operating system. To run Delph INS on Mac you must install a virtual machine software as Oracle Virtual Box and run Delph INS inside the virtual machine.

  • Is it possible to run several versions of Delph INS on the same computer?

    To do that you can proceed as follow:

    1. Install a first version of Delph INS (let's say 3.0.5)
    2. Copy the folder C:\Program Files (x86)\iXblue\DELPH INS Subsea into another location (let's say C:\DELPH INS Subsea\3.0.5).
    3.  Uninstall DELPH INS
    4.  Install another version of DELPH INS (let's say 3.0.7)
    5.  Copy the folder C:\Program Files (x86)\iXBlue\DELPH INS Subsea into another location (let's say C:\DELPH INS Subsea\3.0.7).
    6. Uninstall DELPH INS
    7. Make two shortcuts on your desktop. First one "DELPH INS Subsea 3.0.5" to C:\DELPH INS Subsea\3.0.5\DelphIns.exe and second one "DELPH INS Subsea 3.0.7" to C:\DELPH INS Subsea\3.0.7\DelphIns.exe

    You know have two versions of Delph INS installed side by side.

  • When data are imported, I have the following message: WARNING : Suspicious UTC data will not be used for clock drift compensation (simulation time 1.07, utc time [.]

    The warning messages during the conversion of the raw data file indicates that the UTC synchronization of the INS during the survey is bad (no PPS). During the conversion of the raw data file, DELPH INS use the UTC synchronization data to suppress the drift of the internal clock of the INS but in this case this feature have a bad effect due to the fact that the ZDA data is not received regularly by the INS.

    You should turn off the automatic drift compensation by editing the PostProPhinsDecode.conf.xml located in the DELPH INS installation folder (C:\Program Files (x86)\IXBLUE\DELPH INS or C:\Program Files\IXBLUE\DELPH INS) and change the setting compensateClockDrift from true to false. After converting the file think to revert this value to true.

  • How to concatenate multiple post-processing files

    Q : When using the data logger from the web based MMI it is possible to split the data in multiple files. Delph INS can not handle multiple raw post-processing data files, how to use those files?

    R : You need to concatenate the split files into a single file before loading it into Delph INS. The COPY command from the command line can be used to do that: COPY /B file01.dat+file02.dat+file03.dat result.dat Since version v.2.4 Delph INS can load multiple raw post-processing data files and perform the concatenation of those data files.
