Septentrio GNSS receivers to guide train systems for Wabtec

Septentrio is providing GPS/GNSS receivers to Wabtec, a global company specializing in equipment, digital solutions and services for freight and transit rail systems.

Wabtec is implementing Septentrio GNSS receivers in its GoLINC Edge platform, providing positioning, connectivity, data storage and enhancing positive train control (PTC) with the adoption of higher precision positioning technology.

The enhanced navigational reference capability can benefit U.S. railroad operations as Septentrio GNSS receivers are installed on Wabtec’s latest GoLINC mobile data center platform operating onboard freight locomotives. Two GNSS receivers are being installed on each locomotive to provide precise positioning information as part of the GoLINC system.

Septentrio receivers are also being installed as position reference modules along 30,000 miles of track. They will provide GNSS corrections to the rover receivers aboard the locomotives for reliable and accurate positioning, even in difficult environments such as when tracks run alongside mountains, around cliffs or under foliage.

“The Septentrio GNSS receiver was chosen based upon its superior performance and has proven to have the technology advantage that our customers are looking for,” said Michael Miner, GoLINC product manager at Wabtec.

Wabtec’s GoLINC system — comprising networking, communications and applications management platforms — makes trains smarter by collecting numerous parameters about the train and its route.

GoLINC is integrated with Wabtec’s PTC solution, which functions as a safety overlay and is designed to enforce existing railroad signal indications and other operating rules. Moreover, PTC provides critical information about proximity of work zones, movement authorization, switch positions and other operational data.

“For two decades, Septentrio has been delivering GNSS receivers to customers requiring accuracy, reliability and safety,” said Neil Vancans, Septentrio vice president of global sales. “We have pioneered and fine-tuned capabilities such as position reliability and interference robustness driven by our customers in markets such as offshore energy, mining and construction.

“Over the last several years, we have been working closely with the transportation and logistics sector as well,” Vancans said. “Cooperation with Wabtec offers an excellent opportunity to further deploy our high-precision positioning technology in the rail industry, where the unique capabilities of our GNSS hardware and software match perfectly with the accuracy and safety demands of positive train control.”

Beyond PTC, the high-precision GPS infrastructure along the track will enable other applications such as drone flights for rail inspection.

Septentrio will be exhibiting its latest GNSS receivers at the Railway Interchange exhibition and technical conference, which runs Sept. 22-25 in Minneapolis, Minn., USA.

CHC Navigation has released and is immediately shipping its new i90 IMU-RTK GNSS Series receiver. The i90 IMU-RTK GNSS Series is designed to dramatically increase GNSS real-time kinematic (RTK) availability and reliability.

The i90 is powered by the company’s latest inertial measurement unit (IMU) and RTK technology to provide robust and accurate GNSS positioning in any circumstances.

Unlike standard micro-electro-mechanical (MEMS)-based GNSS receivers, the i90 GNSS IMU-RTK combines a high-end calibration and interference-free IMU sensor with a state-of-the-art GNSS RTK engine and advanced GNSS tracking capabilities.

The i90 is designed to increase productivity and reliability of survey projects. No complicated calibration process, rotation, leveling or accessories are necessary with the i90 GNSS Series. Just a few meters’ walk will initialize the i90 internal IMU sensor and enable RTK survey in difficult field environments. The i90 GNSS automatic pole-tilt compensation boosts survey and stakeout speed by up to 20%.

“Our new i90 IMU-RTK GNSS Series is pushing the boundaries of conventional GNSS survey by extending RTK positioning availability and reliability,” said George Zhao, CEO of CHC Navigation. “CHCNAV is the GNSS technology enabler, making high-end GNSS solutions available for every surveyor.”

CEA-Leti and Orolia announce FlexFusion positioning and navigation technology

​Combining data from GNSS and IMUs ensures accuracy during GNSS outages.

Leti, a research institute of France’s CEA Tech, and Orolia have announced a new sensor-data-fusion engine that ensures resilient positioning and navigation even in cases of GNSS jamming or spoofing.

Orolia is a leader in accuracy and performance for terrestrial, aeronautic and naval transportation positioning, navigation and timing applications.

Called FlexFusion, the algorithm technology processes data from GNSS, inertial management units (IMU) and odometers to provide precise positioning in all conditions.


Orolia will present its latest technological developments at ION GNSS+, booth 311, taking place in Miami, Florida, Sept. 17-19.


FlexFusion’s design relies on a modelization of GNSS and IMU (triple-axis accelerometer, triple-axis gyrometer and triple-axis magnetometer) output for synthetic trajectory generation.

The fusion approach exploits Bayesian estimators, such as Kalman filters. The first algorithm was setup on modeling signals, and its optimization relies on an extensive real-life sample database acquired through field test. This process used CEA-Leti’s HYLOC reference platform, which provides a reference positioning of a few centimeters.

More than 100 trajectory samples were collected in urban, suburban, forest and mountain environments with different GNSS outage conditions.

The new positioning technology supports edge artificial intelligence (AI) because the data-fusion algorithm is performed locally to ensure that positioning and navigation information is available locally and is failsafe even in case of jamming or spoofing of GNSS data.

“Recent events have demonstrated that it is possible to change the course of a ship or force a drone to land in a hostile area by simply spoofing GPS signals,” said CEA-Leti CEO Emmanuel Sabonnadière. “The increasing reliance on a GNSS for the execution of military operations and terrestrial, aeronautic and naval transportation requires using positioning and navigation systems that are able to detect GNSS outages and provide resilient position and navigation features.”

A version of FlexFusion that demands less of the CPU implements a loose coupling algorithm that uses GNSS receiver-output positions as entry of the algorithm. An advanced version implements a tight coupling fusion algorithm of GNSS and IMU data that significantly enhances the resilience of positioning and navigation under real-world conditions.

This novel approach enables total control of treatments and filtering applied to raw signals, which increases performance of the fusion. It also improves positioning performance in particular if there are fewer than four GNSS satellites available, or when there are recurrent multi-trajectories, which sometimes occur in urban canyons.

CEA-Leti has licensed the patented FlexFusion algorithm to Orolia.

“Orolia is integrating FlexFusion in a new version of its VersaPNT product, the first compact, all-in-one and resilient positioning, navigation and timing (PNT) system for vehicles and blue force tracking, tactical UAV navigation and marine applications,” said Thierry Delhomme, EMEA general manager, Orolia. “This powerful algorithm helps deliver on the promise of VersaPNT as an always-accurate PNT system that operates in any environment.”

FlexFusion development was supported and partially funded by the Easytech program of IRT Nanoelec, thanks to the French National Program “Programme d’Investissement d’Avenir” ANR-10-AIRT-05.

U-blox GNSS modules help UAVs carry out life-saving work

The u-blox ZED-F9P, a high-precision GNSS module that delivers centimeter-level accuracy within seconds, has been incorporated into the latest electric Tron F90+ fixed-wing unmanned aerial vehicles (UAVs).

Quantum-Systems, a German company that specializes in electric VTOL (vertical take-off and landing) aircraft for civilian use, manufactures the Tron F90+, which is employed in mission-critical logistical activities such transporting emergency blood reserves to remote locations. Other uses include mining and agriculture-related tasks.


Quantum-Systems and u-blox are both exhibiting at Intergeo in Stuttgart, Germany, Sept. 17-20. Quantum-Systems is at booth K1.074, and u-blox at booth L1.025.


The Tron F90+ has a 3.5-meter wingspan and can travel at speeds of up to 160 km/hour with a 100-km flight range. It is the latest addition to the Quantum-Systems eVTOL UAV platform designed for cargo, inspection, survey and mapping, and reconnaissance in adverse conditions. Other models include the Trinity F9, Scorpion and Vector UAVs, all of which feature u-blox F9 high-precision GNSS technology.

In developing the Tron F90+ UAV, the Quantum-Systems engineering team needed accurate enough position data to ensure that VTOL operations would always go smoothly, and the valuable payloads were protected from damage.

Through the multi-band real-time kinematic (RTK) and raw code and carrier-phase data available to the ZED-F9P, the necessary positioning correction is assured and the pilot can complete even difficult maneuvers. Absolute position accuracy can be brought down to 3-5 centimeters.

Septentrio has expanded its GNSS/INS portfolio with the AsteRx SBi, a new housed GNSS/INS receiver. The ruggedized AsteRx SBi fuses high-accuracy GPS/GNSS with a high-performance inertial sensor to provide reliable positioning and 3D orientation for machine control and logistic applications.

Within its rugged, waterproof enclosure, a high-performance GPS/GNSS is coupled with an industrial-grade inertial sensor to provide high-accuracy, reliable positioning and 3D orientation (heading, pitch, roll).

Offering the flexibility of either single or dual antenna, AsteRx SBi is designed for quick and easy integration into any machine monitoring or control system. AsteRx SBi packs performance and durability into a single, compact box. Reliable location and 3D orientation data is streamed with a high update rate and constant low latency.

“AsteRx SBi was designed with ease of integration and reliability in mind. Its compact, ruggedized housing is optimized for easy clamping to any machinery,” said Danilo Sabbatini, product manager at Septentrio. “It has all the features and tools needed for straightforward integration into machines or large robotic systems.”

Septentrio reliable centimeter-level positioning is based on true multi-frequency, multi-constellation GNSS (GPS, GLONASS, Galileo, BeiDou, QZSS) technology. AsteRx SBi combines GPS/GNSS and an industry-grade IMU (inertial measurement unit) to deliver precise positioning together with 3D attitude.

Septentrio’s unique GNSS–IMU integration algorithm enables continuous positioning in environments of low satellite visibility where short GNSS outages are possible. This is referred to as coasting or dead reckoning, and can happen near high structures, under bridges or under thick foliage. This makes AsteRx SBi a robust positioning solution for machinery operating in environments challenging for GNSS, such as in container yards, urban canyons or near cliffs.

AsteRx SBi comes with built-in industry leading Advanced Interference Mitigation (AIM+) technology. In busy urban environments electromagnetic waves can interfere with GPS and GNSS signals. AIM+ offers protection against such interference resulting in faster set-up times and robust continuous operation. A built-in power spectrum plot allows users to analyze interference, helping locate its source and mitigating it.
