Description
TOGSNAV is a fully comprehensive and fully integrated navigation system for ROVs that builds on the TSS core fibre optic gyro technology and inertial navigation capability by ading a fully couple and fully integrated Teledyne phased array Pioneer DVL.
Available in three standard heading accuracy variants: 0.1° (TOGSNAV1), 0.3° (TOGSNAV3) and 0.5° (TOGSNAV5) with further options of DVL performance; 600kHz (100m) and 300kHz (275m), as well as an optional XRT (Extended Range Tracking) that offers a 50% increase in bottom tracking range.
Inertial position data is produced using an advanced Kalman filter for superior performance, alongside the accurate heading, attitude and heave capabilities. Additional external coupling is available (GPS, USBL and LBL), as well as accepting input from an external depth sensor and sound velocity via an external SVS.
The system benefits from the Pioneer DVL offering BM8 mode, flexible triggering, optional XRT, highly accurate time of validity output, and transducer and system helath monitoring. It comes with a built-in INS-DVL calibration function, making it easy to perform location-based calibration, whilst removing the need for expensive sea trials, for optimal accuracy.
With an alignment time of 10 minutes offering less downtime and more operational time, the TOGSNAV is built for OEM ROV manufacturers and operators, and with a number of options available, it is highly flexible and is ideally suited to installation on a wide range of ROVs.
