The commissioning of the four latest Galileo satellites will result in better services to end users

The latest batch of four Galileo satellites - GSAT0219, GSAT0220, GSAT0221, and GSAT0222 - has been commissioned for operational use.

On 11 February 2019, the four satellites launched from the European spaceport in Kourou, French Guiana, on July 25 2018, were put into service following the completion of the relevant commissioning activities. This means that the Galileo constellation is now providing services with 22 satellites.

“This is another important milestone for Galileo and the European Union. Each satellite that is commissioned brings us closer to our full operating capacity. More satellites in operation mean better coverage and more availability, which translates into increased accuracy and better services for users,” European GNSS Agency (GSA) Executive Director Carlo des Dorides said. “The entry into service of the latest four satellites will boost Galileo service provision around the world.”

Thanks to the addition of four more satellites to the Galileo constellation, users will be able to reap the high accuracy benefits of multi-constellation capacity, but it goes further than that, according to Rodrigo da Costa, Galileo Services Programme Manager at the GSA.

“Today we finished the testing characterization of the satellites that were launched last July,” da Costa said. “The satellites are now ready to provide services to users, and with 22 satellites now in operation users will not only be able to benefit from Galileo signals in combination with other constellations, but the possibility of using Galileo as a stand-alone service also increases.”

GSA at the helm

The 10th Galileo launch was the second for which the GSA was responsible for the mission’s Early Orbit Phase (EOP) and In-Orbit Testing (IOT) phase, overseeing Spaceopal - a joint venture between Telespazio and DLR-GfR - in its role as Galileo Service Operator (GSOp).

The EOP and IOT are one of the most important phases of a space mission during which the satellite is launched, put into the correct orbit and the satellite platform and payload elements are gradually switched on and tested.

Galileo – because Accuracy Matters!

A huge number of end users stand to benefit from the improved coverage offered by the latest satellites. It is only just over two years since Galileo Initial Services were declared in December 2016, but already over 600 million devices around the world are using Galileo. To make Europeans more aware of how they are already benefitting from Galileo services, the European Union has launched the Accuracy Matters campaign.

The new campaign includes a series of short video clips that give an entertaining glimpse of everyday situations where ‘Accuracy Matters’ to anyone using location data on their smartphones. The videos can be viewed on a dedicated YouTube channel.
