TethysL Support

As part of the TethysL effort, in March 2022 we started adjustments in the TethysDash system (both backend and frontend) to allow operators to select and schedule missions that have been written in TethysL.


From the operator's point of view, other than noticing additional or renamed mission scripts files (with file name extension .tl), there are no other changes at all in terms of the subsequent preparation and scheduling.



  • Complete end-to-end TethysL mission exercises across various LRAUV deployments over the past few months have been satisfactory.
  • More mission scripts are planned to be converted to TethysL.


  • DashUI 4.9.6: Any available TethysL mission files are now also included when selecting a mission for scheduling.

  • Backend 4.8.7: The API has been expanded to describe TethysL mission scripts as needed for the corresponding Dash UI functionality, which is mainly in terms of providing details about all mission parameters (name, default value, units), including those of any inserted missions or aggregates.

  • Execution on the vehicle: The LRAUV software has been enhanced to support execution of missions originally written in TethysL.
