The satellite
The satellites has 30 highly powerful KU band transponders, which transmit a 36MHz frequency range and are distributed among two fixed beams over Europe and England, and two steerable beams that can be pointed anywhere above Middle East, South and Eastern Asia, and South Africa.
HellasSat has created a network of strategically placed telecommunications' partners, supporting television broadcasters and IP-based services, powerful direct-to-home services and occasional provision of dedicated capacity for television programs.
The satellite is controlled via two proprietary TT&C stations located in Greece and Cyprus, whistle our Carrier Monitoring Station ensures the high level and reliability of transmission quality.
