Navigation

Nucleus1000

A sensor hub that makes vehicle control and navigation possible.

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

Overview

The Nucleus1000 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 Nucleus1000's capabilities, click here.

  • Currents
  • Bottom track

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

  • Small ROV
  • Micro AUV
  • Coastal USV

Integration

Unlike typical DVLs, the 300m rated Nucleus1000 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 Nucleus1000 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 Nucleus1000, enabling those vehicles to perform longer and more efficient missions. The Nucleus1000 software provides visualization of outputs and sense-checks of sensors, including a 3D visualization of the sensor’s AHRS.
