The CCIR,
considering
that the broadcasting-satellite service (BSS) is normally expected to provide service to a relatibely large that in minimizing the effects of feeder-link noise on the overail link noise budget the cost and complexity of that the satellite output e.i.r.p. is maintained at the nominal output level during feeder-link fades by
that higher up-link power requirements would affect only a few feeder-link stations;
that in terms of availability, rain fades on the down link would only have a local affect on the performance
that a further degradation of the overall link due to thermal noise occurs due to the non-linearity of the
a)
geographical area encompassing a large population of receivers;
b>
the BSS receiver will be minimized;
c)
employing techniques such as automatic gain control (AGC);
d)that higher up-link power requirements would affect only a few feeder-link stations;
e)
whereas rain fade on the feeder link would affect performance over the whole service area;
