From: Bradley S. Brahms <Brahms@USC-ECLC>
In a recent message it was stated that with three working TDRS
satellites the shuttle would be in contact with earth 100% of
the time. Yet with only TDRS-1 working the shuttle would be
in contact only 20% of the time.
Question: Why only 20% and not more?
Something seems wrong with this statement. The only way the shuttle
could be in contact with earth 100% of the time with only three
satellites would be if each covered 33.33% of the orbital paths.
If you include the current ground base tracking system, of course
some of it would overlap TDRS-1, a number around 38% or so
comes up.
Would someone please explain to me this delima(sp?)? Thank You.
