CFD Sales Inc. (President: Koji Mitani, Headquarters: Nagoya, Aichi), the general distributor in Japan, announced that QYSEA has released the next-generation inertial navigation system for underwater drones, "U-INS Plus."
Automatic navigation and route planning, now standard in drones, are realized underwater.
Through sensor fusion technology that combines the proprietary Q-DVL acoustic Doppler velocity log and positioning, QYSEA, which pioneered automatic navigation on the seabed plane (U-INS) globally in 2024, has evolved it into "U-INS Plus" after about a year of development to support not only planar but also vertical (elevation) automatic navigation.
By combining satellite positioning and sensors, high-precision navigation underwater becomes possible, enabling automatic travel not only horizontally but also vertically and while maintaining distance from irregularly shaped walls.
The sensor module compatible with U-INS PLUS features a modular design that can support multiple QYSEA FIFISH series models.
For detailed information on features and compatibility, please check the CFD Sales press release or contact our representative via the inquiry page.
By combining satellite positioning and sensors, high-precision navigation becomes possible underwater
On the water surface, absolute coordinates are acquired via GNSS satellite positioning, and after diving, the Q-DVL and IMU sensors continue real-time position estimation and correction. High-precision navigation is now possible even underwater where GNSS signals do not reach.
With a 5-minute setup, even a small team can smoothly start inspections.
