PARIS - Watch the Hylas-1 launch live, due to take place on Friday 26 November during a launch window between 19:39 and 22:54 CET.
The first 'Highly Adaptable Satellite' is an advanced satellite system focused on providing high-speed Internet connectivity for Europe.
There are two main antennas on Hylas-1, one on either side of the satellite. The larger, double antenna operates in the high-frequency Ka-band, and has been engineered to serve hundreds of thousands of broadband users throughout Europe at the same time. This antenna splits its Ka-band beam into eight highly concentrated spot beams targeting different European regions.
This multi-beam architecture offers much higher broadband capacity than typical wide beam systems. With Hylas-1, each and every user enjoys a direct two-way link to the satellite through a dedicated terminal – efficient system design means domestic antennas are extremely compact, with small dishes of around 70 cm in diameter.
To maximize the total number of users served, the radio frequency resources allocated to the mission are reused within each separate spot beam.
The result is that Hylas-1, while comparatively small for a telecom satellite, can cater to large numbers of widely dispersed users – and its performance-to-cost ratio is correspondingly high.
Hylas-1’s second antenna offers wide beam coverage of the European continent in Ku-band, which is highly prized because of increasing frequency congestion.
Hylas-1 is ESA’s first public–private partnership resulting in a full satellite system. The commercial operator, UK-based Avanti Communications, has contributed the majority of the mission budget and will use the satellite to deliver broadband services to customers. ESA’s involvement focuses on the highly adaptable payload that gives Hylas-1 its name.
Hylas-1’s reconfigurable nature comes from a number of key payload elements developed by EADS Astrium in partnership with ESA: The Generic Flexible Payload (GFP) consists of densely integrated and interconnected state-of-the-art electronic devices, creating an unprecedented level of system flexibility.
Hylas-1 will be launched from Kourou, French Guiana, aboard an Ariane 5 shared with the Intelsat-17 telecommunications satellite.
