How to use Fusion 2 LBL and INS dongles

17 May 2022

To enable flexibility of use of Sonardyne INS and LBL systems, Fusion 2 software has been designed to be modular.

This allows equipment spreads to be purchased at their base functionality and upgraded only if the offshore project requires it. This means you only pay for added functionality when you need it. This is achieved with the use of hardware dongles that the user must attach to the system to provide the functionality required.

SPRINT(Nav) position aided

If you want to use a SPRINT(Nav) using position aiding (USBL aiding for example), you plug in the Fusion 2 INS dongle supplied with the SPRINT(Nav) unit. If you have an old SPRINT software dongle, it can be upgraded for free to Fusion 2 INS.

SPRINT(Nav) range aided / sparse LBL / SLAM

If you want to use a SPRINT(Nav) using range aiding (sparse) including SLAM capability, you must plug in the Fusion 2 INS dongle supplied with the SPRINT(Nav) unit. The owner of the dongle must have paid for range aiding (SPRINT LBL RANGE AIDING SPARSE UPGRADE) which will have set the dongle to enable Fusion 2 INS for both position aided, and range aiding (sparse).

Full (standard) LBL

If you want to do full LBL i.e., same as what you would do with Fusion 1 (baseline calibrations, structure tracking, mobile Compatt tracking, etc), you must plug in a Fusion 2 LBL dongle. Fusion 1 LBL dongles can be upgraded to Fusion 2 LBL providing the dongle owner has paid for a Fusion 2 LBL software upgrade licence.

Running both INS and full LBL simultaneously

If you want to run both Fusion 2 INS (position and/or range aided), and full LBL from a single computer, you must plug both the SPRINT(Nav) dongle programmed for what you need, and the Fusion 2 LBL dongle, into the computer at the same time.
