EGNSS on the core of the drone revolution – Drones Information
The European GNSS (EGNSS) is at the heart of the drone revolution and future underground services. EGNOS and Galileo add significant value to drone navigation, positioning and related applications, and the use of their differentiators will be instrumental in developing new business opportunities. Receiver manufacturers, aware of the benefits that GNSS can bring to users, are eager to adopt Galileo and EGNOS and pass those benefits on to their users.
A growing number of drone applications require accurate position information. According to the GSA’s 2019 GNSS market report survey, nearly 50% of drone users expect horizontal accuracy below 10 cm and 38% expect vertical accuracy below 10 cm. This increase in performance is critical for several drone applications and cannot be achieved without amplifying the GNSS signal. The EGNOS Open Service can increase the GPS signal with a minimum accuracy of 3 meters in the horizontal and 4 meters in the vertical plane compared to 17 and 37 meters with the GPS not extended.
Galileo: a must for drone operators
Regardless of whether drones are automatically returned to the operator, building inspections performed, or just maintaining geo-awareness to avoid obstacles or no-fly zones, GNSS has become a must for drone operators. With Galileo satellites, GPS can use signals from more satellites as well as dual frequencies in addition to GPS to determine their position, which improves accuracy and also increases the availability of received signals.

EGNSS receivers for drones are already populating the market, and Europe provides around 12% drone receivers worldwide. Companies like u-Blox, Septentrio, Novatel and Javad adopted Galileo and EGNOS early on and invested in the technology that is now revolutionizing the drone industry. Thanks to these forward-thinking companies, EGNSS is now a standard feature for drones. To date, 190 EGNOS-compatible or Galileo-compatible chipsets and modules are available on the market. You can discover them here.
The urban environment can present various challenges to the reception of GNSS signals. Galileo-capable receivers with several constellations offer significantly better performance. Earlier this year, the EGNSS4RPAS project carried out EGNSS-enabled drone flight tests. The results showed that the use of Galileo in the dual constellation with GPS significantly improved the accuracy compared to GPS-only for both the horizontal and vertical dimensions.
Supporting EGNSS-based drone innovation
The GSA MyGalileoDrone, the largest European drone competition, started in July. The competition, which can be submitted by September 15, 2020, is aimed at the design and development of drone-based applications or services using a Galileo / EGNOS-enabled receiver. The use of EGNSS is understood in a broader sense, and Galileo and EGNOS can be integrated into the flight platform, ground control station or other operational devices such as a smartphone or even as part of U-Space services. The total prize pool for the competition is EUR 230,000, the first prize EUR 100,000.
“MyGalileoDrone is a fantastic initiative. Septentrio looks forward to the innovation solutions that will emerge from this competition to analyze possible synergies with their products, ”said Gustavo Lopez, Market Access Manager at Septentrio.
The GeomaticsOnTheMove ideas competition is another exciting opportunity for drone enthusiasts to showcase their EGNSS solutions. The survey price competition is also looking for applications that incorporate the use of additional technology, including remote sensing data sources such as drones.
