`
`ASTRA IB and HI? followed in I99‘! and 1993 respectively.
`each adding Id new channels up to the complete occupancy of
`the FSS hand {lB.'95|.'l to ll.'?lJB EH1} with AS channels ASTRA
`1D was then launched in I994. bringing the channel number totisl
`on this orbital position and estending the FSS hand down to
`l{l.TDlJ GHL
`The Scandinavian DEMAC transmissions have now moved to
`other satellites. so the T"v' standard used by analogue trans-
`missions on ASTRA is now escl usively PAL.Table A.l [Appendices]

`
`system.
`The Eutelsat mellite system on l3"E {Eutelsat ll-F1 and the
`‘Hot Bird‘ series} ‘I-'|ticl1. with ASTRA. is the second most impor-
`tant For Europe has chosen a relatively similar approach.
`although its missions are more diverse.
`The currently used 1'-‘SS band now goes down to ]fl.7‘fll1| EH1.
`due to an extension of thirteen 33 l|v'lHa channels {I H} to III}
`with Hot Bird 5.
`The Eutelsat sateflites use dil'l‘e1-ent types of beams depending
`on their rnifiion and generation l.EttteIsat [I-Fl or the Hot Bird
`series}. and a new channel numbering system has been developed
`lf‘norn1aI' channels of 33 MHz on a grid of l'E|‘.IE-1 l'v'lHa and
`313 MHz on a grid ol‘ 2fl.'.l5 l'vlHL and some *wide‘ channels of
`ill or ‘F2 l|vlHa. see Table A.2,'t.
`The French Teleeo-rn IA [E"Wl. Teleeorn EB l5""'-‘ll and Telecorn
`1C{3"E}5nleIIilfi.. launched in lifill and I992 use the high portion
`of the FSS band. oI'ten therefore referred to as the 'Telecorn‘ band
`{l 2.5-I115 EH1}; this band has been divided into 11 channels of
`36 lvIl:Ia on a grid oI"Il MHz {Fig. 2.3]. There. the five main line-
`to-air French SECAM channels can be received lTelecon1 EB}
`along with the analogue pay-Th’ Canal Satellite collection or
`‘bouquet’ t'Teleoorn EA. although probably not beyond the end
