Linux - Multicast DVB-S router for EUMETCast

Mon, 10 Oct 2011 04:19:11 +0000

This simple script transform a linux box into a DVB-S Satellite router to receive data from Eurobird 9E used by EUMETSAT to redistribute weather satellite image.

REQUIRE: DVB Tools SMCroute PCI Card supported by Linux/DVB Tools (ex. Skystar 2)

Recentemente ho rifatto i puntamenti di alcune parabole, qui in particolare il grafico dello spettro del satellite Eurobird 9° Est (Ex Hotbird 2 ora riposizionato) facente parte della flotta Eutelsat.
