AUVs’ Attitude and Heading Reference System
Our sensors are designed for seamless integration into your autonomous underwater vehicle (AUV), ensuring continuous collection and real-time transmission of data on roll, pitch, and magnetic-based heading.
This data is crucial for accurately determining the AUV’s orientation and ensuring stability during underwater missions, allowing for precise navigation and control in challenging underwater environments.
Attitude and Heading Reference Systems (AHRS) are vital in ensuring that AUVs can maintain accurate orientation and heading during their missions. We developed an AHRS that combines data from accelerometers, gyroscopes, and magnetometers to determine the AUV’s attitude (pitch, roll, and yaw) in real time. This continuous feed of orientation data is crucial for autonomous vehicles operating underwater, where traditional GNSS systems cannot provide reliable positioning.
Externally-aided INS solution for AUVs
Our externally-aided INS solution provides comprehensive roll, pitch, heading, and heave data, along with precise navigation when paired with external positioning solutions.
Additionally, our products are of compact size and cost efficient, making high-performance inertial sensors relevant where size matter.
Inertial Navigation Systems (INS) play a key role in AUVs by enabling precise navigation in GNSS-denied environments. Our INS sensors combine data from gyroscopes, accelerometers, and sometimes magnetometers to provide continuous information about the vehicle’s velocity, position, and orientation. Our INS solutions allow AUVs to track their path accurately even in deep-sea environments where traditional satellite-based navigation signals are unavailable.
Motion and navigation systems for AUV
In AUV applications, AHRS ensures that the vehicle can stabilize itself in turbulent waters, navigate accurately, and adjust its motion according to the changing underwater environment. For example, AUVs used in seabed mapping rely on precise attitude data to maintain a stable platform for their sonar or other sensors. Without accurate attitude information, the vehicle’s data collection could be compromised, leading to errors in mapping or inspection tasks.
For underwater survey missions, INS is particularly valuable. It helps AUVs calculate their trajectory over time, allowing operators to execute precise mapping or monitoring tasks. With its ability to provide real-time feedback on position and motion, INS is critical for navigating through complex underwater terrain and avoiding obstacles like underwater structures, wreckage, or natural formations.

What is the difference between AUV and ROV?
The main difference between an Autonomous Underwater Vehicle (AUV) and a Remotely Operated Vehicle (ROV) lies in their control and operation. AUVs are autonomous, operating without a direct human operator, pre-programmed to follow specific missions. Battery-powered and untethered, AUVs offer freedom of movement, making them ideal for tasks such as seafloor mapping and environmental monitoring.
AUVs can cover vast distances due to their autonomy. ROVs, on the other hand, are controlled by operators via a tether that connects them to a ship or platform. This tether provides power and communication but limits their range, making ROVs ideal for underwater inspections and repairs requiring real-time control.
