Putting Galileo in the driving seat for autonomous vehicles

You are here

Accurate positioning is vital for autonomous vehicles. Now, a new sensor using Galileo’s GNSS signals will provide exactly that, thanks to an international collaboration between Deimos Engenharia and Accurision, fostered by ESA Space Solutions network.

Automated and autonomous driving depend heavily on different sensor technologies incorporated into the vehicle's sensor fusion engine. For positioning, it’s important to have a range of different technologies for redundancy reasons, including Global Navigation Satellite System (GNSS), which provides absolute positioning based on radio signals to complement visual sensors like cameras. 

A partnership between Portuguese space specialist company Deimos Engenharia and Austrian start-up Accurision has created a highly accurate positioning sensor using Europe’s Galileo GNSS system. Galileo provides world-class navigation, offering a natural solution for terrestrial applications, such as sensors for autonomous driving but moving from an initial idea to a practical solution is a complex process.  

Spotting potential and spreading the news

In 2013, Instituto Pedro Nunes (IPN), ESA Space Solutions Centre in Portugal identified Deimos Engenharia’s GNSS receiver as having exciting potential applications on Earth. Developed specifically for the Galileo GNSS system, it relies on radio signals to better determine a user’s position and time. As a result, the technology was shared across the ESA Technology Broker Network in 16 countries. 

Deimos Engenharia had been studying potential applications of this technology, including in unmanned aerial vehicles, for some time. “We wanted to make the most of the unique features of the Galileo system, which is why we decided to develop our own receiver. We needed to master the receiver technology and have full control at its deepest level to develop the product and integrate it in advanced navigation solutions,” remarks Deimos Engenharia Director Nuno Ávila. 

Around the same time, Brimatech, an ESA Technology Broker in Austrian, met an entrepreneur searching for high precision satellite-based positioning sensors for autonomous driving. 

“Within three weeks of meeting Accurision’s CEO Gunnar Fleisch at a conference, we had eight technology suggestions for him, pre-checked by our ESA network partners. That was impressive!” remembers Brimatech’s Andrea Kurz. 

From the proposed space technologies offered, it was the GNSS receiver from Deimos Engenharia that best suited the application.

Accurision is now using the Deimos solution to develop the GUIDANCE™ GNSS Sensor ASIC for autonomous driving. This takes advantage of one of the world’s most advanced civil GNSS signal, Galileo E5 AltBOC, to provide unparalleled robustness while achieving the required precision in dynamic rural and urban environments necessary for autonomous driving. It also features an integrated ionospheric delay estimation engine (IDEE), integrated interference detection and a mitigation engine (IDME) to further improve overall performance. 

Accurision’s key aims with the new sensor are robustness, integrity, accuracy and precision. GUIDANCE will be ready to support the upcoming Galileo E6 High Accuracy Service, which will be available free of charge from late this year. 

 

The complexity of brokering technology transfers 

Making this international cooperation happen involved considerable effort. IPN and Brimatech brokered the first meeting between the two parties and supported them to agree and sign a technology transfer agreement, enabling future downstream technical developments.  

The partnership between Deimos Engenharia and Accurision teams is a clear example of the power of ESA’s ‘behind the scenes’ network and how a united European approach to space is fundamental to fostering the economies and societies through space technology.

“Technology transfer is an elaborate activity,” explains Carlos Cerqueira, IPN’s Innovation Director. “Its cornerstone is the fit between technology and market requirements, but in the end what it takes is an excellent relationship with all parties, the ability to spot a need, find a matching offer and get the timing right. With Deimos, it was no different. It took time, but substantial economic impact is just about to happen.”

In future there will be autonomous vehicles relying on Galileo’s GNSS via the GUIDANCE™ GNSS Sensor ASIC, based on a patent jointly owned by the two companies for their Galileo Code Sensor – all thanks to the far-sightedness and hard work of ESA Space Solutions partners network.  To further foster this technology transfer, Accurision received the support of the ESA Business Incubation Centre (ESA BIC) in Austria, where it was incubated. “It is our mission to support ground-breaking business ideas, building on existing European high-quality space capacity,” says Martin Mössler, Managing Director of Science Park Graz, General Manager of ESA BIC Austria.
