Subsea Inertial Navigation Systems (INS) developer Exail, has released the Rovins 9 DVL, a new all-in-one system that combines the best of inertial navigation and Doppler Velocity Log (DVL) technologies.
With this new tightly integrated system, Exail can provide 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, in a single housing, Exail advanced Fiber-Optic based INS with a Nortek DVL. This 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 designed for subsea companies looking to maximize efficiency, and allows for higher levels of reliability, with a position accuracy of up to 0.02%TD and a heading accuracy of up to 0.01°RMS.
The Rovins 9 DVL is designed 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, capable of deployment down to 6,000 meters.
“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,” said 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.”
