Re: Why do we have LOS, when we have all these TDRSes?

Just minutes ago, I heard Capcom mention that the ISS was going into an
LOS, and that they would resume their conversation, once they were out of
the LOS.

As far as I can see, there are 10 TDRS satellites distributed fairly
evenly, so that there should be no LOSes.

Why are they still talking about LOSes?

The main reason is we have to fly at 51.6 deg inclination to accommodate the
Russians. Back when we were going to do a 28 deg orbit (Space Station
Freedom), we would have had full-time views of one or more TDRSs. That 51.6
causes us all kinds of problems, from comm to thermal.
