12 seconds—that’s how long it took to make history. On 17 December 1903, two bicycle shop owners from Ohio, USA, Orville and Wilbur Wright, completed the first powered flight of a heavier-than-air aircraft. The flight covered 36 metres at a speed of just under 11 kilometres per hour and lasted only
As our reliance on Global Satellite Navigation System (GNSS) technologies grows, measures which safeguard the integrity of positioning and timing signals become more important. Recognising this, the European Commission has introduced Galileo OSNMA.
The European Commission, as Programme Manager of the EU Space Programme, announces a major milestone for EGNOS, Europe’s satellite-based augmentation system. On 25 August 2025, the GEO-3 satellite Eutelsat 5 West B officially transitioned from test to operational status, broadcasting the EGNOS Signa
The European Commission and the European Union Agency for the Space Programme (EUSPA) will host a webinar titled “Introducing the new Galileo authentication service, OSNMA” on 1 September 2025 at 14:00 CEST to present Galileo’s new authentication service.
On Friday July 25th, 2025, at 11:03 p.m. local time (02:03 a.m. UTC, 04:03 a.m. CEST, on July 26th, 2025), MicroCarb satellite, were launched from Europe’s Spaceport in French Guiana. The launch was performed using an Arianespace operated Vega C rocket.
OSNMA enables Galileo satellites to transmit a “digital signature” along with their standard Open Service navigation data. This signature allows receivers to verify that the signal they are receiving genuinely originates from Galileo and not from a malicious or spoofed source.
