Galileo Satellite Navigation System Satellites Arrival

9 May 2018The Galileo satellite navigation system two satellites (23 & 24) have arrived in Kourou, French Guiana at Europe’s spaceport. The two satellites for the Galileo satellite navigation system are being prepared for their launch that is planned in July from the jungle space base. The two satellites were brought in  on a Boeing 747 cargo jet in the evening of May 4th in French Guiana.

The satellites were unloaded, still in their protective air-conditioned containers, and transported by truck to the cleanroom environment of the preparation building within Europe’s Spaceport. This pair of Galileo satellite navigation system satellites will be launched along with another two Galileo satellites, which are due to be transported to French Guiana later this month. The quartet will be launched together on a customised Ariane 5 on July 25th.

The Galileo System began Initial Services on 15 December 2016, and a growing number of commercial devices are using Galileo today. Completion of the constellation should improve Galileo’s positioning accuracy further still.

But Galileo satellites will continue to be launched into the future: a further 12 Galileo ‘Batch 3’ satellites were ordered last June, supplementing the 26 built so far to provide further in-orbit spares, and replacements for the oldest Galileo satellites, first launched in 2011. A steady stream of orbital spares, ready to replace satellites reaching the end of their operational lives, is essential to ensure Galileo continues operating seamlessly.

Looking further ahead, with the aim of keeping Galileo services as a permanent part of the European and global landscape, replacement satellites will be required by the middle of the next decade, offering improved performance and added features.

About Galileo

About Galileo Satellite Navigation System Satellites

Galileo is Europe’s own global satellite navigation system, consisting of both the satellites in space and their associated ground infrastructure.

The definition, development and in-orbit validation phases were carried out by ESA, and co-funded by ESA and the European Commission. This phase created a mini-constellation of four satellites and a reduced ground segment o validate the overall concept, ahead of further deployment.

Success led to the current Full Operational Capability phase, fully funded by the EU and managed by the Commission. The Commission and ESA have a delegation agreement by which ESA acts as system design authority and procurement agent on behalf of the Commission.
