Undisturbed Navigation

iXblue Attitude and Heading Reference Systems (AHRS) and Inertial Navigation Systems (INS) are Fiber-Optic Gyroscopes (FOG) based renowned for their high-end performance and reliability. Able to operate in GNSS denied, multipath or difficult environment (building, trees, tunnels, mines), they offer undisturbed navigation, accurate georeferencing, and precise pointing.
They are perfectly suited for applications such as industrial engineering (tunneling, mining, construction work…) and mobile mapping.

Reduce the Cost of your Industrial Engineering Operations

Mining Operations

Choosing a premium FOG INS/AHRS/IMU induces cost savings in the long run. On top of the inherent qualities of FOG (no maintenance cost, very low failure rate…), our systems’ high performance and quick bootup time means your operations will benefit from consequently lower idling time.

Mobile Mapping

A FOG IMU can measure the Earth rotation accurately and therefore offers a gyrocompass capability natively. On FOG based products, True North is found in a couple of minutes without moving by the inertial sensors aided with a one-antenna GNSS receiver. A contrary, with a pure MEMS IMU, a dual antenna GNSS receiver is required to provide the heading before moving. A FOG IMU has also a North-keeping capacity far much better than a MEMS IMU: no measurable heading drift during GNSS outages (tunnel, parking, underground…) and capacity to fly long straight lines with excellent heading accuracy for airborne applications. This is also a key feature for underground applications where GNSS is not usable and where True North is required.

Easy to interface

Our INS and AHRS are no-hassle, plug-and-play, easy-to-use systems which can be fitted on any platform. They benefit from a straightforward web interface, for compatibility on any kind of workstation (down to a small laptop). It logs data internally and has ROS interfacing compatibility, thanks to a driver which iXblue made free to access.

FOG Powered

Premium Performance

 

High-performance of iXblue inertial sensors mainly relies on the mastery of the FOG (Fiber Optic Gyroscope) technology by iXblue. FOG allows to find North in any conditions and maintain heading accuracy in harsh environments. This advantage is emphasized either in pure denied environments like tunneling or mining, or in challenging georeferencing operations.

Highly Reliable Technology

 

iXblue core technology is used in all the company’s inertial products and is being operated in a wide range of applications. Our systems benefit from millions of working hours, and from a huge track record. The FOG core MTBF (Mean Time Between Failure) technology thus reaches over 500 000 hours.

ITAR-free

All of our inertial devices are ITAR-free, thanks to a commitment towards full control of horizontal and vertical integration. All critical components are designed and manufactured internally, by iXblue.
