Improved accuracy of mass positioning and geolocation service users

UNION project description

The objective of the UNION project, coordinated by ROKUBUN and framed in the European call Receiver technologies for high-precision in mass-market de la European Union Agency for the Space Programme (EUSPA), is to improve the precision of the users positioning services and massive geolocation (users of autonomous vehicles, unmanned aerial vehicles and smartphones, among others), while trying to achieve new objectives of general interest in the field of positioning and navigation.


UNION is a new satellite positioning technology

Positioning by satellite

To achieve the objectives, UNION will be based on the use of existing permanent station infrastructures in the territory, such as the ICGC CatNet network, on the development of new calculation algorithms and on the integration of other positioning services and technologies, always bearing in mind the new possibilities and services offered by the European GNSS Galileo Constellation.


UNION is a new satellite positioning technology for accurate and real-time navigation on mass market devices.
