The University of Technology of Compiègne, France, has hosted a live demonstration of the first autonomous vehicle to use the Galileo GNSS constellation. As part of this demonstration, a Renault ZOE electric car has been autonomously driven on tracks and on public roads in a world's first for the Galileo program.
Participants in the event had the unique opportunity to ride in an autonomous vehicle fitted with an innovative positioning engine developed by the ESCAPE project - the ESCAPE GNSS engine (EGE). The EGE leverages Galileo signals and services to provide a core positioning component in autonomous vehicles. It was designed and prototyped by the ESCAPE project, funded under the European GNSS Agency’s (GSA) Fundamental Elements program.
GSA and European Commission representatives, the French and Spanish national authorities and the automobile industry took part in the demonstration of the Galileo-enabled autonomous vehicle.
Cars equipped with the EGE were showcased in two demonstrations at the event. During the first demo on a Renault ZOE electric car, participants and journalists had a unique opportunity to get on board the vehicle and take a driverless ride on the University of Technology of Compiègne (UTC) track.
In the second demo, a second vehicle was driven on a public road in Compiègne to demonstrate the potential of the system in a peri-urban environment. There were no passengers in this car, but the participants were able to watch a live video of the test broadcast via 4G with the estimated position obtained using the EGE along with RTK.
The ESCAPE prototype
The EGE prototype design includes several major components, including a novel multi-frequency, multi-constellation automotive-grade GNSS receiver. The main distinguishing feature of the ESCAPE receiver is its ability to precisely and simultaneously process signals from two different GNSS bands and from different satellite constellations. Although this capability is common in high-end professional receivers, it is cutting-edge in the automotive Tier-2 panorama.
The receiver is also a first-of-a-kind device in its segment to support the new Navigation Message Authentication (NMA) service of Galileo - the open E1 signal. Finally, the new GNSS receiver comes with several core signal-processing enhancements: better receiver sensitivity and tracking capability, multipath mitigation, more intermediate frequency (IF) channels and flexibility in routing IF samples, jamming detection and mitigation, and optimisation of the GNSS data flow.
The result is an ESCAPE GNSS sensor that combines a high-end GNSS technology traditionally reserved for professional applications, innovative dual-band Galileo processing, as well as all the hardware and software safety aspects that are needed to certify the component for the automotive market.
