Global Navigation Satellite Systems Engineering, Policy, and Design
After years of studying the concept of using low-Earth orbit (LEO) navigation satellites to supplement the Galileo system, the European Space Agency (ESA) is ready to move forward with an in-orbit demonstration as part of its new FutureNAV program.

ESA’s Ariane 6 launch vehicle, on which the deployment of the EU’s Galileo GNSS satellite constellation now depends, has taken another step towards first flight. A fresh series of hot fire tests of the rocket’s upper stage and all-new Vinci engine is now underway at Germany’s DLR center for engine and stage testing in Lampoldshausen.

The European Space Agency’s new navigation head, Francisco-Javier Benedicto Ruiz, has a lot to say about GNSS, both present and future. We recently spoke with him about his views on satellite navigation, signal vulnerability and authentication, and the agency’s working relationship, or not, with Russia. The technical team behind the Galileo authentication service and industry representatives developing alternative positioning, navigation and timing solutions also share insights.

Speakers at the 14th European Space Conference in Brussels discussed the need to defend EU assets against unfriendly attacks. Recent events in Eastern Europe would seem to lend force to such concerns, as the European Union makes headway toward the intersection of civil infrastructure and security and defense.

The European Union Agency for the Space Programme (EUSPA) has published its Earth Observation (EO) & GNSS Market Report, an outgrowth of its annual GNSS Market Report now that the agency has also taken on Earth observation among its administrative responsibilities. The Report is compiled and written for all those making these technologies part of their business plan and developing downstream applications.

Arianespace recently announced it will launch a total of eight new Galileo satellites over the next few years.
The European Union Agency for the Space Programme (EUSPA) selected Arianespace to launch four new Galileo satellites for Europe’s satellite navigation system, according to a news release. This comes after the European Space Agency’s (ESA) order to launch four satellites last October and will complete the deployment of first-generation Galileo satellites.

The latest version of the Galileo Open Service Definition Document (OS SDD), updated November 2021, describes upgrades enacted in the Galileo system since May 2019: improvements, current constellation status and updates in the ground infrastructure that increase its robustness. This is the last update foreseen before Galileo Open Service reaches Full Operational Capability (FOC).
