Satellite Communications/one transponder one beam ?

Question
Sir, very basci question. If I am correct,in previous C-band and Ku-band satellites,the quantity of on-board transponders is same as the the quantity of beams supported (one transponder one beam) ? Same situations in today's HTS ?

Answer
Hi Mr Feng,
I am not sure what you may be meaning by "one transponder one beam). Satellites are
designed with coverage area in consideration and the ground trace with maximum power
as zero dB contour and Edge of Coverage as minimum power point, so far as beam is
considered. If you mean "beam" as identification for the satellite beacon, then
each satellite has only ONE beacon per satellite and NOT for each transponder.
Also transponders are not necessarily same in numbers in each satellite and depends
on the standard transponder bandwidth as well as spectrum and applications as
well as Technology.
I am sure there is no change in this pattern for HTS too.
