Galileo-European-GNSS-Header1

The European Commission and the European GNSS Agency (GSA) confirm that the first generation of Galileo will already provide users with high accuracy and authentication services. Both the commission and GSA have adopted the Galileo Commercial Service Implementing Decision. The Commercial Service will complement the Galileo Open Service by providing an additional navigation signal and added-value services in a different frequency band.... read more

KU Leuven: Galileo signals will become more difficult to falsify

February 13, 2017By
Galileo satellites (EU).

Researchers from the Department of Electrical Engineering at KU Leuven (University of Leuven, Belgium) have designed authentication features that will make it more difficult to send out false Galileo signals. Professor Vincent Rijmen and doctoral student Tomer Ashur from the Department of Electrical Engineering (ESAT) at KU Leuven have advised the European Commission on ways to make Galileo signals more... read more

Geoscience Australia, Lockheed collaborate on multi-GNSS SBAS research

February 13, 2017By
To improve precision navigation, a second-generation SBAS will use signals from both GPS and Galileo, and dual frequencies, to achieve even greater GNSS integrity and accuracy.

Geoscience Australia, an agency of the Commonwealth of Australia, and Lockheed Martin have entered into a collaborative research project to show how augmenting signals from multiple GNSS constellations can enhance positioning, navigation and timing for a range of applications. Other partners are Inmarsat and GMV. The research project aims to demonstrate how a second-generation Satellite-Based Augmentation System (SBAS) testbed can... read more
