Schedule Confirmation

Avanti Communications Group plc

Schedule Confirmation

On 12 July 2010, Avanti (AIM: AVN), the broadband satellite operator, announced that the Board's estimate was that there was a risk of schedule delay of up to six weeks from the proposed end of September launch of the HYLAS 1 satellite.

The Company now confirms that it has agreed the launch slot on an Ariane 5 launch vehicle which opens on 15 November 2010 with launch expected on that day or within a few days thereafter.

The HYLAS 1 spacecraft has successfully completed its assembly, integration and test campaign and is therefore fully complete and ready for launch.
