Since the beginning of 2000s, the INS iXblue  products has been largely used by many railway companies for tracks mapping and data georeferencing. 

Thanks to its navigation know-how, iXblue offers now, a simple real-time , railway standards compliant, performant and cost-efficient localization solution. Our high-performance Atlans-R7 inertial navigation directly answers this need. It provides undisrupted data, in all environment including where GNSS signals are disturbed or non-existent. 

 iXblue promotes also largely by its own high-grade works and engineering activities within industrial groups an ERTMS safe and precise embedded localization systems. 

Robust Localization within GNSS-denied Environments

In normal situations, Atlans R7 works in tandem with a GNSS system to provide enriched positioning and georeferencing data. However, it still functions alone, when the GNSS signal is unavailable or disturbed. For instance: when passing through tunnels, woods, urban canyons…

Atlans R7 provides  position, speed and attitudes of the train. Directly connected via Ethernet link or 4G/LTE antenna, Atlans-R7 provides in real time the precise train data to all consumers as passengers on-board/on station, as driver when connected to its aiding-driving tools and as fleet manager on station for traffic optimisation.

Best-in-class Performance

Atlans R7 is based on FOG (Fiber-Optic Gyroscope) technology. It is the result of more than 30 years of research and development and is today considered to be the best gyroscope in the world: its performance is deemed genuinely unlimited.

Atlans R7 is the compact and cost-efficient iXblue inertial solution for Rail localization able to guarantee the utmost geolocalisation performance during a long GNSS-free. Atlans R7 initialization does not require any train movement thanks to the iXblue FOG triad gyrocompassing capability.

Highly Durable Solution

INS based on Solid-State FOG Technology and reliable railway components

 

Fiber-Optic Gyroscopes are truly solid-state passive systems. Indeed, the FOG technology does not involve any movement of mechanical parts causing dithers, vibrations, frictions and resulting in parts’ weariness and noise. This ensures many benefits for the user: robustness of the system (Power-on and Forget), cost-effectiveness and the lowest cost- of-ownership on the market.

Extensive Trackrecord

Atlans R7 is based on the Atlans A7 INS. The latter is already used by several clients in the civil engineering field. More broadly, the FOG technology on which Atlans R7 is based equips all of our INS and have been proven on the field for a wide variety of applications (maritime, autonomy, defense…).

Last but not least, iXblue has an extensive history in the rail domain, with Atlans R7 being used as a reference. It is embedded on french railway network (TGV and RER).

Full Spectrum of Rail Applications

Metrology

 

The use of cameras and lidars for network mapping or lasers for measuring the track geometry increased exponentially with rail operators. With these new technologies, the need for accurate and reliable positionning and georeferencing of captures images and data arose.​ Atlans A7 and Atlans R7 directly answer to this need. ​

Moreover, their native ability to provide undisrupted georeferencing position, speed and attitude is a key advantage for 2D network mapping.​

 

 

 

Train localisation

Inertial IXblue solutions reply to the real challenge the train localisation providing an undisrupted system localization even during long-term navigation without GNSS (case of urban environment or “white” zone) thanks to its embedded train vehicule model and its innovative inertial virtual balises.​

Another key advantage of iXblue localisation is the gyro-compassing capability which not requires any train movement for initialization.​

​The navigation data fusion expertise of iXblue has extensively supported many customer trials as reference.

Key Partner of the
ERTMS Project

iXblue is the project leader of LOC4RAIL ERTMS program for a safe and  precise localisation solution.   

The disrupted and innovative safe architecture led by inertial technology proposed by iXblue benefits directly to European operators and can be quickly proposed to the ERTMS market.

The embedded solution does not involve any complex on-board equipments as radar-dopper  or external optical sensors but a simple calculator with the latest iXblue IMUs based on virtual inertial balises coupling with the digital map. The scalability and the modularity of this architecture fit totally with RCA (Reference CCS Architecture)  or OCORA (Open CCS  On board Reference Architecture) specified by ERTMS Group.

Powerful and User-Friendly
Post Processing Software

Unleash the potential of Atlans R7 by using our APPS post-processing software. This powerful analytics tool benefits from an easy-to-use interface. It is ready to process both iXblue sensors’ data and third party’s.
