Nucleus 1000

1000 m

A deep-water-rated sensor hub that makes vehicle control and navigation possible.

  • Compact size optimal for small ROVs and AUVs
  • Integrated AHRS and INS for pre-calibrated attitude, heading, and position information
  • Dedicated vertical beam for altimeter information

Overview

The Nucleus 1000 is a sensor package that has all the necessary sensors and data products to aid in subsea navigation and vehicle control. This includes estimates of distance from the surface and bottom, attitude, heading and velocity. To learn more about the Nucleus 1000's capabilities, click here.

A shallow water (300 m rated) version of the Nucleus 1000 is also available.

  • Currents
  • Bottom track
  • Altimeter

Highlights

  • Compact size optimal for small ROVs and AUVs
  • Integrated AHRS for pre-calibrated attitude and heading information
  • Dedicated vertical beam for altimeter information

Usage

  • Integration with small ROVs or AUVs where payload is limited
  • Navigation for vehicles which don't require survey-grade accuracy
  • Backup navigational aid for coastal USVs
  • Increase vehicle capabilities with combined current profiling and navigation solution

Integration

Unlike typical DVLs, the 1000m rated Nucleus 1000 is equipped with a pre-calibrated and pre-synchronized AHRS, temperature and pressure sensors, bringing users closer to true navigation while greatly reducing integration work. For those requiring a full positioning solution, the Nucleus can be provided with an optional INS firmware feature.

Reliability

The Nucleus 1000 provides many of the features of a Nortek DVL, including water track in case of bottom track loss, rigorous testing in the demanding conditions of the Oslo fjord, and multiple data quality checks, all in a compact package.

Results

Integration of a guidance and navigation system on small vehicles becomes achievable, effective, and affordable with the Nucleus 1000, enabling those vehicles to perform longer and more efficient missions. The Nucleus 1000 software provides visualization of outputs and sense-checks of sensors, including a 3D visualization of the sensor’s AHRS.
