Schedule Confirmation

Avanti Communications Group plc (AIM: AVN), the broadband satellite operator, has today been notified by Arianespace of the potential (but not certainty) for several weeks of schedule slippage in relation to the readiness of the Soyuz launch at Kourou. Arianespace further confirmed that in accordance with the Launch Service Agreement it is ready to launch HYLAS 1 using an Ariane 5 vehicle if necessary which will ensure the launch will take place by end of September 2010 in accordance with the HYLAS 1 delivery schedule. The Ariane 5 is rated at the same low risk level by insurance underwriters in terms of reliability and quality. Therefore the potential for Soyuz slippage does not have an impact on HYLAS 1 launch schedule and no decision is required yet as to the selection of the launch vehicle.
