Since the beginning of 2000s, iXblue’s Inertial Navigation Systems (INS) have 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 INS 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 system.
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 and on station, as driver when connected to its aiding-driving tools and as fleet manager on station for traffic optimization.

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.
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.
