Two more satellites join Galileo constellation

June 8, 2017By

Two further satellites have formally become part of Europe’s Galileo satnav system, broadcasting timing and navigation signals worldwide while also picking up distress calls across the planet, reported the European Space Agency. These are the 15th and 16th satellites to join the network, two of the four Galileos that were launched together by Ariane 5 on Nov. 17, 2016, and... read more

Galileo provides healthy signals 97.33 percent of the time

June 5, 2017By

Europe’s Galileo satellite navigation system has undergone its first performance report since it started work at the end of last year, and it passed with flying colors, said the European Space Agency. The European GNSS Agency, GSA, through its GNSS Service Centre, has published the first of its regular quarterly performance reports on Galileo. This European GNSS (Galileo) Initial Services... read more

Upgrades to monitoring stations support EGNOS

May 29, 2017By

Upgrades to the monitoring stations underpinning Europe’s EGNOS satnav augmentation system will support its evolution, said the European Space Agency. The current 40 Ranging and Integrity Monitoring Stations (RIMS) sites across Europe and beyond are the bedrock of the European Geostationary Navigation Overlay Service (EGNOS), supplying highly accurate and robust satnav information that can be relied on for safety-critical purposes.... read more

ESA: Space debris enters ‘more feared exponential trend’

May 23, 2017By

In April, the European Space Agency (ESA) hosted the 7th European Conference on Space Debris at ESA’s Satellite Control Centre in Darmstadt, Germany. There, international experts discussed ways to head off the threat of space junk. ESA estimates there are roughly 5,000 objects larger than 1 meter, 20,000 objects over 10 centimeters and 750,000 “flying bullets” of around one centimeter.... read more
