Delph Subsea Positioning

Datasheet

Specifications

Delph Subsea Positioning is an intuitive and dynamic software package used to plan, operate and post-process Exail subsea positioning products. Integrating the full range of Exail subsea systems, Delph Subsea Positioning (Delph SP) simplifies the planning, simulation, operation and post-processing of subsea positioning tasks. Comprising three intuitive and user-friendly core modules, Delph SP is an easy-to-use yet powerful tool enabling even the most complex subsea operations by making each step of the subsea positioning operation simpler, error-free and faster, saving vessel and man time.

Post-processing module (Delph INS)

Finally, Delph INS is the post processing module that completes the Delph SP suite. This module takes either real inertial data or data generated by the Navigation Simulation module (coming soon) and runs Inertial Navigation System algorithms to provide statistics and status all along the navigation (or simulated navigation). It also generates automatic report regarding the navigation of the vehicle. Strong data management, highly intuitive visualization, editing and processing features, together with diverse export capabilities make the Delph INS post-processing module ideal for quick and easy navigation enhancements. By combining the raw data from the INS and from the complementary aiding sensors (GNSS, USBL/LBL, DVL, depth sensor…) during post-processing, the Post-Processing Module provides higher accuracy for the position, velocity or attitude of the vehicle. The module also produces new comprehensive quality analysis and quality check reports (QA/QC), providing quick, easy and highly intelligible information on the reliability of the collected data.
