In a recent article published by Geospatial World, the European GNSS Agency (GSA) discusses how the EGNOS Open Service and the EGNOS Data Access Service (EDAS) help provide users with improved location performance.

Location plays an important role in many of our day-to-day activities. “Every day we need to locate various points, such as places, businesses, customers and resources,” says GSA Market Development Officer and article author Reinhard Blasi. “Maps are the means we use to place these points into a geographic context, and to create maps, these points need to be positioned.”

In Europe, the European Geostationary Navigation Overlay Service (EGNOS) helps locate these points with sub-meter accuracy in an easy, affordable and flexible way and in real time. It can also boost the data capture, which is usually the most time-consuming process in the development of a mapping or GIS application.

EGNOS was designed to improve GPS performance in Europe. “The EGNOS Open Service provides this improved performance to users of general-purpose applications,” says Blasi. “It is freely accessible through a GPS/SBAS compatible receiver within the area of coverage, and no specific authorisation is required.”

The EGNOS Data Access Service (EDAS), on the other hand, is EGNOS’ internet-based service. It provides free-of-charge access to all the data generated and collected by the EGNOS infrastructure. EDAS gathers all the raw data coming from the GPS, GLONASS and EGNOS GEO satellites collected by all the receivers located at the EGNOS stations, which are mainly distributed over Europe and North Africa. Once the data is received, EDAS disseminates it over the internet in real time and through an FTP archive, resulting in the different services, depending on the protocol and format used and the type of information available to users.

“With EDAS, users equipped with compatible software applications and/or GNSS receivers and having access to the internet can obtain improved accuracy with respect to GPS standalone by implementing advanced positioning techniques,” says Blasi in the article.

This is an excerpt from the 1 September 2017 article entitled European SBAS: EGNOS offers free sub-metre accuracy in Europe published by Geospatial World. You can read the full article here.

Now that surveyors worldwide are able to use Galileo positioning, following the declaration of Galileo Initial Services, all major Precise Point Positioning (PPP) providers in Europe have upgraded to Galileo and more than 50% of real time kinematic (RTK) network providers have already upgraded or have started to upgrade.

At the latest Council of European Geodetic Surveyors (CLGE) General Assembly, which was held in Potsdam in Germany on 29 September 2017, the European GNSS Agency (GSA) organised the second edition of the workshop “Integrating Galileo in RTK networks: success stories and open challenges”, at which industry representatives shared their experience and results received from Galileo performance testing.

At the event, Roberto Capua from Italian public augmentation service provider Sogei and Paul Chambon from French private RTK service provider Terria spoke about the technicalities, challenges and benefits of Galileo inclusion into RTK networks. The two service providers noted in particular that field tests had shown the benefits of Galileo inclusion into the RTK networks.

“The results confirm the usability of the Galileo constellation in high-precision RTK applications and show improved availability, reliability, accuracy and time-to-fix in difficult measuring environments such as urban canyons and under tree canopies,” they said.

New markets, new chipsets

Both service providers highlighted that there are new emerging markets for high precision services, especially in the mass market domain. One such promising sector is autonomous driving, which is slowly becoming a reality due to enhanced positioning systems and the evolution of augmentation services (RTK, PPP, PPP/RTK, etc.).

Capua also underlined the availability of new dual-frequency mass market chipsets using L1/L5 frequencies, which will allow increased positioning accuracy with mass market devices such as smartphones, tablets, wearables. “With E5/L5 capability added to the E1/L1, chipsets and receivers benefit from better accuracy, ionosphere error cancellation, improved code tracking pseudorange estimates, and faster transition from code tracking to phase tracking, among other benefits,” he said.

GSA questionnaire

During the workshop, the GSA also launched a real-time questionnaire that aimed to gain a better understanding of Galileo’s value to end-users, the needs of surveyors and reference network providers, the level of Galileo adoption and challenges users may face when upgrading to Galileo.

The survey showed that end-users have a good understanding of Galileo’s added value, with 69% of the respondents declaring that are convinced that Galileo will improve their work. On the other hand, the survey confirmed there is still an issue with inter-operability between the different brands of RX manufacturers within the RTK-network and that the inclusion of Galileo into the RTK network is expensive.

1st Galileo User Assembly

Information received from the Galileo questionnaire will feed into the discussion at the 1st Galileo User Assembly, which is set to take place next week (28-29 November). Hosted by the GSC at its premises in Madrid, the Assembly will give Galileo users the opportunity to discuss their needs, share their experience, and provide feedback on Galileo performance.

The Assembly will include:

• A Galileo User Consultation Platform (UCP) in 4 thematic groups (transport, mass market, professional and R&D);
• A general update on the Galileo programme;
• Presentations on Galileo Initial Services performance, the Galileo Services Roadmap and the Galileo User Interfaces; and
• A Galileo User Satisfaction Survey.
