Tethys Robotics has developed a new mini-ROV with a Nortek DVL500 Compact DVL sensor

The use of this component, a Doppler velocity sensor, has improved the accuracy of positioning and navigation.

Swiss company Tethis Robotics has launched a small ROV and equipped it with a DVL500 Compact DVL sensor. The company claims that this has allowed the small ROV to achieve good results in terms of autonomous position holding, even in currents that are noticeable to the robot.

I have translated the text as literally as possible, while still maintaining the meaning of the original. I have also used the same tenses and grammatical structures as the original text.

The Nucleus1000 navigation sensor suite now has full INS

 The Nucleus1000 navigation sensor suite now has full INS (inertial navigation system) capabilities, enabling absolute position outputs. It can be used in small AUVs, ROVs, and USVs for navigation (latitude/longitude or X/Y output).

The Nucleus only needs to be provided with a GPS position to begin navigating using absolute positioning.
