Exail Launches New Subsea Navigation System
Exail, a global leader in high-performance subsea inertial navigation systems (INS), has launched a new all-in-one system that combines the best of inertial navigation and Doppler Velocity Log (DVL) technologies: the Rovins 9 DVL.
With this new, tightly integrated system, Exail provides subsea vehicle manufacturers with highly accurate and reliable subsea navigation.
Highly compact for easy vehicle integration, the Rovins 9 DVL all-in-one design combines Exail’s advanced fiber optic-based INS with a Nortek DVL in a single housing. Its tight integration of raw sensor data from both INS and DVL provides operators with highly accurate position, velocity, and attitude information even in challenging subsea environments.
This new all-in-one system is perfectly suited for subsea companies looking to maximize efficiency and allows for higher levels of reliability. The Rovins 9 DVL delivers a position accuracy of up to 0.02%TD and a heading accuracy of up to 0.01°RMS.
“By merging the INS and DVL complementary measurements, the resulting navigation data becomes much more precise and accurate than either system used alone. The ability to connect external sensors such as pressure sensors through the satellite connectors available on the system provides even greater accuracy,” says Maxime Le Roy, INS product manager at Exail.
“The Rovins 9 DVL greatly simplifies the work of subsea operators in the field. The system can be easily integrated into a variety of subsea vehicles, including ROVs, AUVs, and tow fishes, thanks to its unique compact horizontal design and plug-and-play feature.”
The Rovins 9 DVL is an ideal choice for AUV manufacturers and e-ROV operators seeking to save watts without compromising on data processing power. It operates on low power consumption and is highly resistant to high pressure and harsh environments and can be deployed down to 6,000 meters.
Exail’s new all-in-one system is ready for immediate deployment and will help subsea operators save significant time and money, enabling fast in-motion self-alignment and not requiring on-the-field calibration.
