+352 710 725 1ASTRA 4A
ASTRA 4A is a multi-mission Ku/Ka-band satellite located at 5° East.
It offers services for direct-to-home (DTH) broadcasting, cable TV feeds, occasional transmissions and broadband solutions. This satellite provides services to the Nordic, Baltic and eastern European markets, and also provides coverage of sub-Saharan Africa.
The European markets are covered by two Ku-band beams; one beam transmits to the Nordic and Baltic countries and the other towards central and eastern Europe.
ASTRA 4A provides DTH coverage to multiple African markets with a dedicated Ku-band beam from a single orbital position - which eliminates the need for dual-illumination from separate beams. Our customers can uplink and downlink within the African footprint, and also between Africa and Europe: DTH broadcasting out of Europe is available without the need for expensive fibre links.
