The European Union Agency for the Space Programme (EUSPA) has published an online interactive world map providing information about augmentation service providers that support Galileo. Clicking over each country shows the names of the Galileo-ready providers along with the name of the service, type of service and coverage.
The online interactive map is accessible here.
Augmentation service providers deliver a range of high-accuracy GNSS positioning services worldwide, tailored both for professional and consumer markets. Service providers monitor signals from GNSS (GPS, GLONASS, Beidou and Galileo) satellites and generate corrections to significantly improve the accuracy of GNSS standalone positioning. Correction messages are transmitted via the internet, SATCOM or GPRS to GNSS receivers. There are different types of services appropriate to all needs and budgets, offering different levels of accuracy from centimeters to decimeters. These solutions can be used in a number of markets including: mapping, surveying, construction, agriculture, automotive or aviation, to name a few.
Standard GNSS positioning, often affected by several errors, can be corrected using augmentation services to provide a more accurate and precise position. With augmentation services, users can operate their receivers virtually anywhere on the globe and, by means of receiving data from a control center, achieve accuracies ranging from meter to centimeter-level, depending on the hardware, platform and application.
Today, there are different augmentation techniques based on the use of a network of ground-based reference or monitoring stations with known locations that enable to calculate corrections (e.g. differential corrections for RTK or clocks and orbits corrections for PPP). These corrections can then be disseminated, for instance, over the internet or satellites.
The augmentation service provider map is a thematic map updated on a quarterly basis that provides an easy way to visualize the service providers that are able to operate in each country. Clicking on each country shows the names of the Galileo-ready providers along with the name and type of service and coverage.
