Stated goal of providing broadband internet access to people in the areas hardest to reach by terrestrial connectivity means
Ariane vehicle L556, mission V198, placed two communications satellites in orbit.
Hylas 1, for the UK company Avanti Communications, is an Indian ISRO I2K satellite with an advanced Astrium-UK communications payload. Hylas, much smaller than IS-17, has a mass of 2570 kg full, 1125 kg dry and has a Ka-band payload for European broadband service. Its stubby solar panels probably only have a span of 9 meters rather than the 36 m incorrectly reported by the EADS and Ariane press kits.
